Household pollutants can come from a variety of sources including the materials used in your home’s construction, and mold and mildew caused by poor ventilation. Clean air in the home can protect you from carcinogens, allergens, and harmful particulates. Even if you don’t suspect a problem, it’s a good idea to have some type of air quality monitor in the home. Threats like radon and carbon monoxide are colorless, odorless, and tasteless, and you’ll have no clue that there’s trouble until you’re already in the danger zone. The good news is that it’s fairly easy to conduct indoor air quality testing and monitoring yourself: All you need is a few key tools.
The wide range of pollutants, particulates, and allergens that can affect indoor air make it difficult to create an all-inclusive list of poor indoor air quality indicators. However, there are circumstances and signs that could indicate poor air quality in your home, including:
RELATED: Mold vs. Mildew: What’s the Difference?
Not every home requires air quality testing for every potential particulate or pollutant. Often, the types of symptoms you experience and the age and location of the home can help you narrow down potential pollutants. Be sure to consult a doctor if you are experiencing health problems that you suspect are related to your home environment. A doctor can help identify and treat health issues related to exposure to mold, radon, and carbon monoxide.
How is air quality measured? Some monitors use electrochemical sensors that detect toxins while others estimate particulate matter (PM) based on the particulates that pass in front of a laser. It depends on the type of monitor you have and what it’s designed to detect.
Air quality testing can detect harmful odorless gasses like carbon monoxide and radon. Depending on the model, they may also detect volatile organic compounds (VOCs) or pollutants such as airborne particulate matter. More advanced indoor air quality monitors may also measure the room’s humidity and temperature.
Choose a monitor that detects the specific pollutants that concern you. For example, if you live in an area with high air pollution, you’re more likely to need a model that detects particulate matter. Those who live in older homes may want to get a model that detects radon and carbon monoxide (though either can be present in newer homes, too).
Our Recommendation: Temptop M10 Air Quality Monitor – Get it at Amazon for $92.99
This portable air quality monitor’s sensors track airborne particulate matter, VOCs, and formaldehyde with a simple display and interface.
Mold tests come in various formats, including swabs, tape strips, air pumps, and petri dish tests. Swabs and tape strip tests collect potential contaminants from a surface like a counter or tabletop. The results from a swab test come within a few minutes, though you may not know the exact type of mold.
Tape strips, air pumps, and petri dish tests require the collected demo be sent to a lab for analysis. While these tests are more accurate than a simple swab test, it can take anywhere from a few days to a few weeks to get the results. Additionally, petri dish tests can get contaminated from other particles in the air. Tape strips and swabs can also get contaminated by other particles on the tested surface.
Air pumps offer a closed system that’s less likely to get contaminated, though they tend to cost more. Set the mold test up near the home’s ventilation or in the area where you suspect mold or a contaminant. However, always follow the directions on the test kit for the best results.
Our Recommendation: Seeml Labs DIY Mold 3 Test Kit – Get it at Amazon for $32.99
This kit comes with three tests (one swab and two tape strips), which offer same-day (that the results arrive) results from a lab.
RELATED: How to Test for Mold
Radon gas naturally occurs as a byproduct of the breakdown of the uranium found in certain rocks and soil. The gas can seep its way into a home through the foundation until it reaches harmful levels.
Radon tests detect levels of the gas over time. Short-term tests take 90 days or less, while long-term tests can take several months. The results from these tests are usually interpreted by a lab. Continuous tests monitor radon levels at all times and alert you if high levels of radon are detected.
Depending on the type of radon test you use, the testing process may require installing detection sheets or other materials in an area suggested by the manufacturer. The key is to follow the instructions on the test.
Our Recommendation: Airthings 2989 View Radon – Get it at Amazon for $199.99
This continuous, battery- or USB-operated radon monitor measures indoor radon levels, temperature, and humidity and integrates with the Airthings mobile app to provide the user remote alerts.
Carbon monoxide (CO) is an odorless, poisonous gas that causes confusion, dizziness, and headaches before it causes a loss of consciousness and death. Many smoke detectors these days are combination smoke and carbon monoxide detectors. It’s critically important to have both types of detectors in your home, so you’ll want to make sure that your home safety plan monitors both smoke and carbon monoxide.
Carbon monoxide detectors should be placed outside bedrooms, and anywhere in the house you’d place a smoke detectors. There should be a carbon monoxide detector on each level of the home and near sleeping areas. Carbon monoxide rises with air, so the detector should be placed about 5 feet off the floor on a wall or on the ceiling. Do not put them near a fireplace or open flame.
Our Recommendation: Kidde Nighthawk Carbon Monoxide Detector – Get it at Amazon for $34.99
Kidde’s Nighthawk is a reliable, affordable carbon monoxide detector that sounds when CO levels reach unhealthy levels. We like that it has a digital display and multiple power sources, including battery backup, so it will continue functioning during a power outage.
RELATED: 8 Myths About Indoor Air Quality and the Facts You Need to Breathe Easy
Home air quality monitoring devices will alert you if pollutants reach dangerous levels. However, there are many things you can do to prevent levels from reaching dangerous levels in the first place.
• Check your HVAC system to make sure it’s functioning at peak efficiency.
• Increase the airflow in your home by periodically opening the windows and using fans to circulate the air.
• Stay on top of mold removal and prevention around the home. If you find mold, try scrubbing it with a mold-killing cleaner like bleach or borax. For delicate surfaces, you can use dish soap or diluted white vinegar. Unfortunately, you may not be able to remove mold from porous surfaces, and they may need to be replaced.
Carbon monoxide is incredibly dangerous. If you suspect that there’s carbon monoxide in your home in high or low doses, leave at once. Open windows and doors, and get outside into the fresh air. Contact the proper authorities to get you and the home checked for carbon monoxide poisoning.

Speaking on the certifications received on Wednesday, the Director General, OEQA, Mrs. Abiola Seriki-Ayeni, who spoke with our correspondent at her office at the Secretariat, Alausa, on Thursday, said the certifications showed the important strides the agency had taken in revolutionising the education sector in Africa.
“The certifications (ISO 9001:2015 and ISO 21001:2018) came as a recognition of our achievements in regulating pre-tertiary education in Lagos State through inspection, monitoring, assessment, standardisation and providing assurance of good quality educational services related to teaching and learning,” Seriki-Ayeni said.
She added that the feat also makes OEQA the first state educational agency in Nigeria to receive an ISO certification.
The DG noted earlier in a statement that the OEQA has “curated learning outcomes to inspire intellectual growth for our students and our quest for excellence,” which has made the agency the first government educational agency in Africa “to receive both prestigious ISO certifications. It is a truly historic achievement for us.”
She further stated that the certifications “mark extraordinary firsts for Nigeria and Africa,” noting that the agency is committed to bolstering educational standards and transforming educational landscapes.
While stressing that the Mr. Babajide Sanwo-Olu-led Lagos State Government places a high premium on quality education, Seriki-Ayeni appealed for the support of stakeholders in the education sector, saying, “With your support, we will empower our students with the best education and equip them with the necessary skills to excel.”

Cannabidiol (CBD) is a hemp-derived compound that shows promise for relieving pain, inflammation, and anxiety. Compared with tetrahydrocannabinol (THC), CBD won’t get you “high.”
CBD oil is one of the most common types of CBD products, but it isn’t the only one. You can also take CBD in a pill or capsule. Pills and capsules are easy to use and can provide more consistent dosing than oils, as each dose is premeasured.
However, unlike CBD oils, CBD capsules and pills are subject to additional breakdown in your digestive tract via the first pass effect, which may change the potency.
Currently, the Food and Drug Administration (FDA) doesn’t ensure the safety, effectiveness, or quality of over-the-counter (OTC) CBD products. However, in order to protect public health, the FDA can take action against CBD companies that make unfounded health claims.
Since the FDA doesn’t regulate CBD products in the same way they regulate drugs or dietary supplements, companies sometimes mislabel or misrepresent their products. That means it’s especially important to do your own research and find a quality product.
We’re here to help with our top nine picks of some of the best CBD pills and capsules on the market today. We’ll also go over how to choose a product, as well as cover safety and side effect information.
Where available, we’ve included special discount codes for our readers.
We chose these products based on criteria we think are good indicators of safety, quality, and transparency. Each product in this article:
As a part of our selection process, we also considered:
Additionally, most of the products on this list contain full-spectrum CBD. Full-spectrum CBD, also known as whole-plant extract, has some advantages over isolate — namely, the entourage effect, a theory that states cannabinoids work better together than they do alone.
Navigating the CBD world can be overwhelming, even for more experienced users. Here’s what to look for when evaluating a product.
Look for a product that has a COA from a third-party lab. At a minimum, most brands will include the cannabinoid profile and potency. Check to make sure this matches what’s on the product label.
Some companies also test for contaminants, like:
Products that provide this information (and pass) are your best bets safety-wise.
If the company doesn’t provide a COA or provides one that’s incomplete or old, it probably isn’t the most quality company.
Look for products made with U.S.-grown hemp, which is subject to agricultural regulations.
Also consider the type of hemp. If you’re looking for a product that’s federally legal, look for a full-spectrum product with less than 0.3% THC, or an isolate or broad-spectrum product.
Watch out for red flags when shopping. These include:
You can learn more about how to read a CBD product label here.
When looking for a pill or capsule to suit your specific needs, consider:
For example, if you want something you can use before bedtime, look for a product that contains high levels of linalool, a terpene found in lavender and cannabis. Linalool has been shown to help with relaxation and anxiety, which may aid in sleep.
Consider other factors that may be important to you. For example, if you’re a vegetarian, you’ll want to read ingredient lists closely and look for a product that doesn’t contain gelatin — as many of these products do.
Depending on how easy it is for you to swallow pills, you may also want to consider capsule size and shape.
CBD oils are one of the most popular types of CBD products. They usually come in a bottle with a dropper, which you use to place the oil under your tongue.
CBD pills and capsules, on the other hand, come in a traditional softgel form. You take them as you would any other pill.
Some people prefer capsules to oils because they’re pre-dosed, and they don’t taste like anything. CBD oils can be flavored, but if they don’t have any added flavoring, they can have a sort of earthy taste.
Compared with oils placed under your tongue, capsules may take longer to produce an effect. That’s because capsules are subject to what’s called the “first pass effect.” This means that after you swallow them, they’re partially broken down in your digestive system and liver.
People take CBD capsules for a variety of reasons, including:
They’re a good choice if you’re looking for full-body effects. If you’re hoping for improvement in a localized area, you may want to consider a topical.
Dosing CBD can be tricky. There’s no one-size-fits-all dose, because everyone’s bodies respond differently to CBD. The clinical evidence we have for dosing CBD in humans is limited, and more research is needed before we can determine ideal safe doses.
With that in mind, the golden rule of dosing is “go low and slow.” Start at a low dose, see how it makes you feel, and adjust as needed. Some people find starting with 10 or 20 mg of CBD works, while others may need 40.
Adjusting by 5 to 10 mg at a time is a safe bet. It may take a few weeks of experimenting before you find your ideal dose. You’ll know a dose is just right if you begin to experience a reduction in symptoms.
Keep in mind that full-spectrum or broad-spectrum products can feel more potent than isolate.
Studies show that CBD is considered to be safe and generally well-tolerated in humans at doses of up to 1,500 mg per day. However, CBD users may still experience some side effects.
These can include:
One randomized clinical trial suggested that consuming CBD products with high fat meals can drastically increase CBD concentrations. This may increase the risk of side effects.
Talk with a doctor before taking CBD, especially if you’re taking any medications or supplements. CBD can have significant drug interactions, especially with medications that carry a grapefruit warning.
It can take up to 1 or 2 hours for the effects of a CBD capsule to kick in.
No. By itself, CBD doesn’t cause a “high.” However, many CBD products contain THC. If you take a high enough dose of a potent enough product, you may be consuming enough THC to feel the effects.
Full-spectrum and broad-spectrum CBD capsules may be more beneficial than CBD isolate capsules thanks to the entourage effect. However, CBD isolate may also offer benefits on its own.
CBD capsules typically contain CBD oil. They’re just a different delivery mechanism. Some people prefer capsules because they dislike the taste of oils. Others find that capsules are more convenient and less messy than CBD oils.
Yes, but make sure to pay close attention to the dosage of each product.
CBD pills are easy to use and offer reliable dosing. However, they may break down in the digestive tract, making them feel less potent.
You’ll need to experiment until you find your “just right” CBD dosage. Be sure to talk with a doctor before trying CBD.
Is CBD legal? The 2018 Farm Bill removed hemp from the legal definition of marijuana in the Controlled Substances Act. This made some hemp-derived CBD products with less than 0.3% THC legal at the federal level. However, CBD products containing more than 0.3% THC still fall under the legal definition of marijuana, making them illegal at the federal level. Some states have legalized CBD, so be sure to check state laws, especially when traveling. Also, keep in mind that the FDA has not approved nonprescription CBD products, and some products may be inaccurately labeled.
Paris CNN —
A swimming competition that was supposed to serve as a test event ahead of the 2024 Paris Olympics was canceled due to poor water quality in the Seine, casting doubt over the French government’s audacious plan to clean up the famous river before next summer.
World Aquatics, the international governing body for swimming and water sports, and the Paris 2024 organizing committee said above-average rainfall in July had left the Seine too polluted to swim in. The decision to cancel the event, the Open Water Swimming World Cup, was made by World Aquatics in consultation with the French Swimming Federation (FFN) and public health authorities.
“World Aquatics is disappointed that water quality in the Seine has resulted in the cancellation of the World Aquatics Open Water Swimming World Cup, but the health of our athletes must always be our top priority,” said World Aquatics President Husain Al-Musallam.
Olympic organizers expressed confidence that the Seine would be better prepared for swimmers when the Games open next year. The Paris 2024 organizing committee in a statement that new infrastructure will be put in place to further Excellerate the water treatment in rainy weather by the start of the Paris Olympics. Contingency measures, such as postponing competitions due to water quality, are also being planned.
Paris plans to make the river Seine the centerpiece of the Olympics. It will feature prominently in the opening ceremony, while several swimming events, paratriathlon and triathlon events are set to take place in its waters.
Clean up efforts have been underway since 2018. Two disinfection units at wastewater treatment plants run by the Paris region public sanitation service will be operational from this summer, and structures that will help to Excellerate water quality, such as a rainwater storage basin, are under construction.
The Paris 2024 organizing committee said that despite the rain, the Seine’s water quality remained clean enough by public health standards to hold swimming competitions, “thus demonstrating the significant progress made.”
French swimmer Caroline Jouisse said she was “frustrated” by the cancellation, adding that the event would have been a “great opportunity” to test the Seine’s waters before the Olympics.
“I am nevertheless happy that all measures have been put in place. Until the last moment and again this morning at 4 a.m. they took samples, they did their best to allow us to swim and that’s great,” she said.
Jouisse added that she remains “confident” for the future.
Paris 2024 said that in the coming days the water quality will be “carefully” monitored. A test triathlon and paratriathlon event is scheduled from August 17 to 20.
“One year before the Games, the sanitation dynamic continues with the completion of the most significant work to Excellerate water quality in the coming months, in particular to deal with these exceptional weather events,” Paris 2024 said.

Vancouver, British Columbia (August 16, 2023) – Vizsla Silver Corp. (TSX-V: VZLA) (NYSE: VZLA) (Frankfurt: 0G3) ("Vizsla" or the "Company") - https://www.commodity-tv.com/ondemand/companies/profil/vizsla-silver-corp/ -announces positive preliminary metallurgical test results for the Copala Resource Area ("Copala") at its 100%-owned flagship Panuco silver-gold project ("Panuco" or the "Project") located in Mexico.
“Based on representative samples from Copala, the largest known structure in the Panuco district, we are pleased to report very high silver and gold recoveries,”commented Michael Konnert, President & CEO of Vizsla Silver. “This is a significant de-risking milestone for the Project and provides positive implications for the ongoing development of the Panuco district. Additionally, these results complement high silver and gold recoveries from the Napoleon and Tajitos resource areas using comparable grinding with both flotation and leaching methods independently. We intend to confirm through the next phase of metallurgical testing and additional flowsheet optimization that the mineralized material from all three primary zones, which make up the bulk of the current project resource base, is amenable to processing via the same flowsheet utilizing the same extraction circuits by testing the combination of flotation and cyanide leaching at both Napoleon and Tajitos.”
Testing Procedure:
The test program was designed and supervised by Ausenco Engineering Canada Inc. and completed by ALS Canada Ltd. out of Kamloops, BC. The testing procedure consisted of drill core being first crushed to -6 mesh and prepared into master composite test charges. A series of flotation tests were then conducted on the samples at primary grind sizes of between P80 70 to 150μm. Simple bulk flotation conditions were applied which included 18 g/t of PAX over 8 minutes of flotation time at natural pH. Precious metal recoveries to the concentrate ranged between 76 to 82% for gold and 78 to 85% for silver.
Flotation concentrate and tails were both subsequently leached using sodium cyanide to maximize gold and silver extraction. Flotation concentrates were subject following varying levels of regrinding prior to bottle roll leach tests using a sodium cyanide concentration of 3000 ppm. Pre-aeration was applied by bottle rolling the prepared feed slurries with ambient air prior to adding cyanide. Flotation tails were subject to bottle roll leach tests using a sodium cyanide concentration of 1000 ppm. Total circuit sodium cyanide consumptions averaged 1.3 kg/tonne for tests that included regrinding.
Gold and silver extractions from the flotation concentrates averaged 96.4 and 98.1%, respectively, for tests that employed regrinding compared with 93.6 and 92.7% without regrinding. Gold extractions appeared to be complete after 24 hours, while silver benefitted from extending the leach to 48 hours. Gold extractions from the rougher tails ranged between 77 and 82%, while silver extractions ranged between 48 and 67% after 48 hours of leaching. The higher extractions were achieved at the finer primary grind sizes. A summary of master composite test results is presented in Table 1.

* T60 Rougher Con leach residue was added to the Rougher Tail leach
Table 1: Flotation plus Cyanide Leach results on Master Composite.
A test was conducted in which the concentrate residue was added to the rougher tail leach, 24 hours into the process, for an additional 48 hours of leaching of this product. This arrangement is represented in Figure 1. In this test (T60), 93.7% and 90.6% of the gold and silver, respectively, were extracted to the combined leach solutions as indicated in Table 2.
Test T55 used a finer primary grind of 70µm P80 returned very good total recoveries of 93.0% and 93.8% for gold and silver, respectively. This test used was performed over a lower leach residence time of 48 hours for both the rougher tails and concentrate. This result indicates that finer primary grinding may be justified. Repeat testing and grinding circuit cost analysis needs to be completed to confirm.

Comminution: The Copala composite material is considered to be hard, returning a bond ball mill work index (BBWi) of 18.6 kWh/tonne, which is higher in comparison with Napoleon deposit (16.8 kWh/tonne).
Future Work Programs
Based on these positive results from Flotation plus Cyanide Leaching for the Copala deposit, further metallurgical testwork is being planned for the Napoleon and Tajitos deposits to further confirm that they are amenable to the same treatment.
In addition, further test work of material from the Napoleon, Tajitos and Copala deposits is planned to better understand and optimise grind size, cyanide consumption, leach kinetics, residence times and recoveries.
Napoleon and Tajitos previous Metallurgical Testwork
Preliminary silver and gold recoveries for the Napoleon and Tajitos resource areas were originally disclosed by Vizsla on February 17, 2022 and March 10, 2023, and are provided in Tables 3 and 4. The float and leach test work that was carried out on the Copala samples has not been specifically evaluated on Napoleon material however, some of the Tajitos samples were tested using a similar arrangement, albeit not with the same application of regrinding or additional leach residence times.

About the Panuco project
The newly consolidated Panuco silver-gold project is an emerging high-grade discovery located in southern Sinaloa, Mexico, near the city of Mazatlán. The 7,189.5-hectare, past producing district benefits from over 86 kilometres of total vein extent, 35 kilometres of underground mines, roads, power, and permits.
The district contains intermediate to low sulfidation epithermal silver and gold deposits related to siliceous volcanism and crustal extension in the Oligocene and Miocene. Host rocks are mainly continental volcanic rocks correlated to the Tarahumara Formation.
The Panuco Project hosts an estimated in-situ indicated mineral resource of 104.8 Moz AgEq and an in-situ inferred resource of 114.1 Moz AgEq. An updated NI 43-101 technical report titled “Technical Report on the Mineral Resource Estimate Update for the Panuco Ag-Au-Pb-Zn Project, Sinaloa State, Mexico” was filed on SEDAR on March 10, 2023, with an effective date of January 19, 2023 was prepared by Allan Armitage, Ph. D., P. Geo., Ben Eggers, MAIG, P.Geo. and Yann Camus, P.Eng. of SGS Geological Services.

Quality Assurance / Quality Control
Drill core and rock samples were shipped to ALS Limited in Zacatecas, Zacatecas, Mexico and in North Vancouver, Canada for demo preparation and for analysis at the ALS laboratory in North Vancouver. The ALS Zacatecas and North Vancouver facilities are ISO 9001 and ISO/IEC 17025 certified. Silver and base metals were analyzed using a four-acid digestion with an ICP finish and gold was assayed by 30-gram fire assay with atomic absorption ("AA") spectroscopy finish. Over limit analyses for silver, lead and zinc were re-assayed using an ore-grade four-acid digestion with AA finish.
Control samples comprising certified reference samples, duplicates and blank samples were systematically inserted into the demo stream and analyzed as part of the Company’s quality assurance / quality control protocol.
Qualified Person
The Company’s disclosure of metallurgical information in this press release has been collated and reviewed by Peter Mehrfert, P. Eng, of Ausenco. All scientific and technical information in this press release has been reviewed and approved by Martin Dupuis, P.Geo., COO for Vizsla. Messrs. Mehrfert and Dupuis are Qualified Persons as defined under the terms of National Instrument 43-101.
Information Concerning Estimates of Mineral Resources
The scientific and technical information in this news release was prepared in accordance with NI 43-101 which differs significantly from the requirements of the U.S. Securities and Exchange Commission (the “SEC”). The terms "measured mineral resource", "indicated mineral resource" and "inferred mineral resource" used herein are in reference to the mining terms defined in the Canadian Institute of Mining, Metallurgy and Petroleum Standards (the “CIM Definition Standards”), which definitions have been adopted by NI 43-101. Accordingly, information contained herein providing descriptions of our mineral deposits in accordance with NI 43-101 may not be comparable to similar information made public by other U.S. companies subject to the United States federal securities laws and the rules and regulations thereunder.
You are cautioned not to assume that any part or all of mineral resources will ever be converted into reserves. Pursuant to CIM Definition Standards, “inferred mineral resources” are that part of a mineral resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling. Such geological evidence is sufficient to imply but not verify geological and grade or quality continuity. An inferred mineral resource has a lower level of confidence than that applying to an indicated mineral resource and must not be converted to a mineral reserve. However, it is reasonably expected that the majority of inferred mineral resources could be upgraded to indicated mineral resources with continued exploration. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, except in rare cases. Investors are cautioned not to assume that all or any part of an inferred mineral resource is economically or legally mineable. Disclosure of “contained ounces” in a resource is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute “reserves” by SEC standards as in place tonnage and grade without reference to unit measures.
Canadian standards, including the CIM Definition Standards and NI 43-101, differ significantly from standards in the SEC Industry Guide 7. Effective February 25, 2019, the SEC adopted new mining disclosure rules under subpart 1300 of Regulation S-K of the United States Securities Act of 1933, as amended (the “SEC Modernization Rules”), with compliance required for the first fiscal year beginning on or after January 1, 2021. The SEC Modernization Rules replace the historical property disclosure requirements included in SEC Industry Guide 7. As a result of the adoption of the SEC Modernization Rules, the SEC now recognizes estimates of “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources”. Information regarding mineral resources contained or referenced herein may not be comparable to similar information made public by companies that report according to U.S. standards. While the SEC Modernization Rules are purported to be “substantially similar” to the CIM Definition Standards, readers are cautioned that there are differences between the SEC Modernization Rules and the CIM Definitions Standards. Accordingly, there is no assurance any mineral resources that the Company may report as “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources” under NI 43-101 would be the same had the Company prepared the resource estimates under the standards adopted under the SEC Modernization Rules.

When used in this news release, the words “anticipate”, “believe”, “estimate”, “expect”, “target”, “plan”, “forecast”, “may”, “would”, “could”, “schedule” and similar words or expressions, identify forward‐looking statements or information. These forward‐looking statements or information relate to, among other things: the exploration, development, and production at Panuco, including plans for resource/discovery-based drilling designed to upgrade and expand the mineral resource.
Forward‐looking statements and forward‐looking information relating to any future mineral production, liquidity, enhanced value and capital markets profile of Vizsla Silver, future growth potential for Vizsla Silver and its business, and future exploration plans are based on management’s reasonable assumptions, estimates, expectations, analyses and opinions, which are based on management’s experience and perception of trends, current conditions and expected developments, and other factors that management believes are relevant and reasonable in the circumstances, but which may prove to be incorrect. Assumptions have been made regarding, among other things, the price of silver, gold, and other metals; no escalation in the severity of public health crises; costs of exploration and development; the estimated costs of development of exploration projects; Vizsla Silver’s ability to operate in a safe and effective manner and its ability to obtain financing on reasonable terms.
These statements reflect Vizsla Silver’s respective current views with respect to future events and are necessarily based upon a number of other assumptions and estimates that, while considered reasonable by management, are inherently subject to significant business, economic, competitive, political and social uncertainties and contingencies. Many factors, both known and unknown, could cause real results, performance, or achievements to be materially different from the results, performance or achievements that are or may be expressed or implied by such forward‐looking statements or forward-looking information and Vizsla Silver has made assumptions and estimates based on or related to many of these factors. Such factors include, without limitation: the Company's dependence on one mineral project; precious metals price volatility; risks associated with the conduct of the Company's mining activities in Mexico; regulatory, consent or permitting delays; risks relating to reliance on the Company's management team and outside contractors; risks regarding mineral resources and reserves; the Company's inability to obtain insurance to cover all risks, on a commercially reasonable basis or at all; currency fluctuations; risks regarding the failure to generate sufficient cash flow from operations; risks relating to project financing and equity issuances; risks and unknowns inherent in all mining projects, including the inaccuracy of reserves and resources, metallurgical recoveries and capital and operating costs of such projects; contests over title to properties, particularly title to undeveloped properties; laws and regulations governing the environment, health and safety; the ability of the communities in which the Company operates to manage and cope with the implications of public health crises; the economic and financial implications of public health crises to the Company; operating or technical difficulties in connection with mining or development activities; employee relations, labour unrest or unavailability; the Company's interactions with surrounding communities and artisanal miners; the Company's ability to successfully integrate acquired assets; the speculative nature of exploration and development, including the risks of diminishing quantities or grades of reserves; stock market volatility; conflicts of interest among certain directors and officers; lack of liquidity for shareholders of the Company; litigation risk; the ongoing military conflict in Ukraine; general economic factors; and the factors identified under the caption “Risk Factors” in Vizsla Silver’s management discussion and analysis and other public disclosure documents. Readers are cautioned against attributing undue certainty to forward‐looking statements or forward-looking information. Although Vizsla has attempted to identify important factors that could cause real results to differ materially, there may be other factors that cause results not to be anticipated, estimated, or intended. Vizsla does not intend, and does not assume any obligation, to update these forward‐looking statements or forward-looking information to reflect changes in assumptions or changes in circumstances or any other events affecting such statements or information, other than as required by applicable law.
