Orosur Completes Phase One of El Pantano JV, Argentina

Orosur Mining Inc. (TSXV:OMI) has successfully completed the first phase of its exploration joint venture (JV) at the El Pantano Gold/Silver Project in Argentina. The company's geological teams have mobilized to the Santa Cruz Province to commence the field exploration program, which lasted approximately two weeks. This phase involved extensive mapping and surface sampling (soils and rock chip) programs over two most attractive prospects identified following the examination of historical data and previous due diligence visits.

The El Pantano Project is subject to an exploration and joint venture (JV) agreement with private Argentinean company DESEADO DORADO S.A.S and its shareholders. The agreement allows Orosur to earn 100% equity in the project by investing US$3 million over five years in two phases. In the first phase, Orosur earned a 51% interest in Deseado by investing US$1 million over an initial three-year period. The second phase involves moving to 100% ownership by investing an additional US$2 million over a subsequent two-year period and granting Deseado a residual 2% net smelter return royalty on the project.

The El Pantano project is located in the prolific Deseado Massif region of Santa Cruz Province in southern Argentina, roughly 45 km from Anglo Gold's Cerro Vanguardia mining camp. The project comprises nine contiguous exploration licences that total 607 km2. The region is barren and sparsely populated, with good access via paved roads and dirt roads. The project is characterized by a major SE-NE trending crustal-scale structure that bisects the project area, which is the primary orientation known to control emplacement of gold and silver mineralisation across the Deseado Massif.

Orosur's geological team has identified two initial prospects within the project area: San Antonio and La Esfinge. The San Antonio prospect lies within the SE of the project area and was explored in a cursory fashion by Minsud Resources Corp. for several years until 2016. Minsud carried out some low-level mapping and sampling of epithermal veins along the main structure, which were the NW continuation of high-grade veins previously identified by other local companies outside the project area. A series of small resistivity and IP surveys were also undertaken. Work by Minsud demonstrated a highly prospective and potentially large epithermal system associated with the eruption of dacitic domes, and evidence of pervasive silicification and argillic alternation.

La Esfinge, the second prospect, lies approximately 5 km along strike from San Antonio to the NW, located directly on the primary regional structure. This prospect is characterized by a large (8 km strike length) silicified hill within a large erosional window whereby the overlying basalts have been removed. The prospect shows evidence of massive silica flooding and the development of alteration and other features that suggest La Esfinge is part of the same epithermal system as San Antonio, but slightly higher in that system. No evidence of historical modern exploration has been uncovered, and it is possible that the prospect is untouched.

Orosur's cautious approach to investing in the El Pantano project balances the risks and rewards of exploration in a high-growth, volatile sector like mining. The company's phased investment strategy allows it to gradually increase its ownership in the project while managing the risks associated with exploration in a volatile sector. By investing in an early-stage exploration project, Orosur has the opportunity to generate significant value through exploration success, offsetting the risks associated with interest rates, market volatility, and geopolitical uncertainties.



In conclusion, Orosur Mining Inc. has successfully completed the first phase of its exploration joint venture at the El Pantano Gold/Silver Project in Argentina. The company's geological teams have identified two promising prospects within the project area, and the company's cautious approach to investing in the project balances the risks and rewards of exploration in a high-growth, volatile sector like mining. With a strong balance sheet and a strategic location near existing mines, Orosur is well-positioned to continue its exploration efforts and potentially generate significant value for shareholders.
