New minor risk - Share price stability The company's share price has been volatile over the past 3 months. It is more volatile than 75% of Canadian stocks, typically moving 14% a week. This is considered a minor risk. Share price volatility indicates the stock is highly sensitive to market conditions or economic conditions rather than being sensitive to its own business performance, which may also be inconsistent. It also increases the risk of potential losses in the short term as the stock tends to have larger drops in price more frequently than other stocks. Currently, the following risks have been identified for the company: Major Risks Earnings have declined by 32% per year over the past 5 years. Revenue is less than US$1m. Minor Risks Share price has been volatile over the past 3 months (14% average weekly change). Market cap is less than US$100m (CA$104.4m market cap, or US$76.2m). New Risk • Dec 03
New major risk - Revenue and earnings growth Earnings have declined by 15% per year over the past 5 years. This is considered a major risk. Ultimately, shareholders want to see a good return on their investment and that generally comes from sharing in the company's profits. If profits are declining over an extended period, then in most cases the share price will decline over time unless the company can turn around its fortunes. A trend of falling earnings can be very difficult to turn around. If the company is well already established it may also be a sign the company has matured and is in decline. In addition, if the company pays dividends it will also likely need to reduce or cut them, striking a dual blow to total shareholder returns. Currently, the following risks have been identified for the company: Major Risks Earnings have declined by 15% per year over the past 5 years. Revenue is less than US$1m. Minor Risk Market cap is less than US$100m (CA$46.2m market cap, or US$33.1m). Anuncio • Aug 19
Tintina Mines Completes Drilling Campaign and Reports Key Geometallurgical Advances to Support 2025 Pea for Domeyko Sulfuros Project Tintina Mines Limited announced the completion of its 2025 drilling campaign at the Domeyko Sulfuros Project, located in the Atacama Region, Chile. The primary objective of the campaign was to upgrade the Inferred Resources reported in January 2025 NI 43-101, and to support the development of a Preliminary Economic Assessment (PEA) in accordance with NI 43-101 standards, reinforcing the Company's commitment to the technical and strategic development of this asset. Preliminary drill results confirm the resource and demonstrate the potential to expand the deposit both to the northwest and at depth. Geometallurgical tests conducted during this phase indicate good copper liberation, low pyrite association, and favorable metallurgical recoveries, validating the technical potential of the ore under operating conditions. The 2025 Domeyko Sulfuro's drilling campaign included 12 diamond drill holes, totaling 5,810 meters. This campaign provided key information for updating the 3D geological models, as well as collecting geotechnical data and core samples for geomechanical testing. The updated resource estimate is expected in September, while complete Cu-Au assay results will be available by the end of August. Currently, 20% of the geochemical results have been received. Some of the main intercepts in quartz-diorite porphyry are shown in Table 1. Partial intercept results from the 2025 drilling program. Partial intercept results from the 25 drilling program.

Tintina Mines Limited Commences the 2025 Drilling Campaign At the Domeyko Sulfuros Project, Atacama Region, Chile Tintina Mines Limited announced the commencement of its 2025 drilling campaign at the Domeyko Sulfuros Project, located in the Atacama Region of Chile. The campaign is primarily aimed at supporting the development of a Preliminary Economic Assessment (PEA) under NI 43-101, reinforcing the Company's commitment to the technical and strategic advancement of this asset. As part of the ongoing development of the Domeyko S sulfuros Project, Tintina Mines Limited has launched a drilling campaign under its 2025 exploration program. The campaign includes a total of 6,000 meters of drilling, aimed at upgrading a portion of the inferred resources to the measured and indicated categories. This work is supported by a prior gap analysis study, which helped identify key opportunity areas to strengthen the project's technical foundation. In parallel, the Company will advance with geometallurgical studies, as well as metallurgical and geomechanical testing -- all critical components to support the preparation of the Preliminary Economic Assessment (PE A). It is worth noting that the deposit was previously mined in its oxide and secondary sulfide enrichment zones, providing a valuable historical dataset of technical, environmental, and community-related information that complements the current evaluation and enhances the robustness of the ongoing analysis. The PEA is expected to be completed by the end of 2025 and will provide a detailed analysis of the project's economics. The Domeyko Sulfuro's Project is an exploration property situated in the Atacama Region the project encompasses 75 mining concessions, covering an area of 10,056 hectares within the Dos Amigos mining district. Strategically positioned 53 kilometers south of Vallenar, the property offers exceptional accessibility, located just 60 kilometers from the Pacific coast and less than one kilometer from the Pan-American Highway, and adjacent to the town of Domeyko. This advantageous positioning significantly enhances its logistical potential. Its low-altitude setting, combined with excellent connectivity and access to critical infrastructure such as electrical power, water, and logistical support, provides substantial operational advantages. From 1997 to 2015, the enrichment blanket at the Dos Amigos target was the focus of open-pit mining operations. During this period, approximately 12 million tonnes of ore, with copper grades exceeding 0.85% (predominantly secondary sulfides), were extracted and processed using heap leaching and solvent extraction-electrowinning (SX/EW) methods at an on-site facility. In February 2024, Tintina completed a NI 43-101 Independent Technical Report for the Domeyko Sulfuras Project, providing a comprehensive overview of the technical characteristics of the property. The most recent NI 43-101 report, issued in January 2025 and prepared by SRK Consulting Chile SpA, has defined an inferred mineral resource of 320 Mt for the Domeyko S sulfide Project, with average grades of 0.36% total copper (CuT) and 0.26 ppm gold (Au) (0.51% copper equivalent (CuEq). The Dos Amigos deposit, located within the project area, hosts open mineralization to the north and southeast, indicating significant potential for resource expansion. Anuncio • Apr 01

New major risk - Market cap size The company's market capitalization is less than US$10m. Market cap: CA$7.13m (US$5.08m) This is considered a major risk. Companies with a small market capitalization are most likely businesses that have not yet released a product to market or are simply a very small company without a wide reach. Either way, risk is elevated with these companies because there is a chance the product may not come to fruition or the company's addressable market or demand may not be as large as expected. In addition, if the company's size is the main factor, it is less likely to have many investors and analysts following it and scrutinizing its performance and outlook. Currently, the following risks have been identified for the company: Major Risks Shareholders have been substantially diluted in the past year (114% increase in shares outstanding). Revenue is less than US$1m. Market cap is less than US$10m (CA$7.13m market cap, or US$5.08m). Minor Risk Share price has been volatile over the past 3 months (16% average weekly change).

New major risk - Shareholder dilution The company's shareholders have been substantially diluted in the past year. Increase in shares outstanding: 275% This is considered a major risk. Shareholder dilution occurs when there is an increase in the number of shares on issue that is not proportionally distributed between all shareholders. Often due to the company raising equity capital or some options being converted into stock. All else being equal, if there are more shares outstanding then each existing share will be entitled to a lower proportion of the company's total earnings, thus reducing earnings per share (EPS). While dilution might not always result in lower EPS (like if the company is using the capital to fund an EPS accretive acquisition) in a lot cases it does, along with lower dividends per share and less voting power at shareholder meetings. Currently, the following risks have been identified for the company: Major Risks Debt is not well covered by operating cash flow (2.1% operating cash flow to total debt). Shares are highly illiquid. Negative equity (-CA$3.3m). Shareholders have been substantially diluted in the past year (275% increase in shares outstanding). Revenue is less than US$1m. Market cap is less than US$10m (CA$5.59m market cap, or US$4.09m). Anuncio • Aug 15
