Promising Developments at Orvana's Taguas Project

Orvana Minerals Corp., a notable player in the mining sector, recently reported their ongoing outcomes from a deep drilling initiative at their 100%-owned Taguas Project, situated in San Juan, Argentina. As of April 7, 2026, the initial borehole (designated TADD–278) has reached an impressive depth of 1,326 meters. This exploration endeavor signals a strategic expansion beyond previous evaluations, focusing on both oxidized gold-silver resources and potential underlying sulfide mineralization. The company aims to push the drilling beyond 1,500 meters, with a target capped at between 1,500 and 2,000 meters.

Geological Insights

The drilling has encountered a vertically zoned hydrothermal system that transitions from a high-sulfidation epithermal environment to a more profound porphyry setting. Notably, the mineral fill observed includes characteristics akin to porphyry-style systems, potentially unlocking extensive copper and gold resources. Preliminary assay results from depths between 715 to 920 meters detail significant gold and copper concentrations with 0.25 g/t gold and 0.12% copper over a substantial 205-meter interval. Notably, the ore body seems rich in pyrite, indicating a promising stratification of minerals.

According to Raúl Álvarez, Orvana's Director of Exploration and Technical Services, the results thus far are promising and provide a solid foundation to further understand the Taguas mineral system.

Details from the Drilling Campaign

The drilling process has been challenging, hindered by structurally complex fault zones. However, the progress made up to around 1,326 meters is noteworthy. The upper layers are largely composed of rhyolitic tuffs, marked by argillic alteration, evolving into more complex fragments at deeper levels, including dacitic volcanics and sericitic-altered intrusions. Observations denote intensified veining patterns alongside the emergence of molybdenum-bearing veinlets, solidifying the hypothesis of a porphyry-type mineralization.

The preliminary assay data showcases robust gold and copper grades, with select intercepts indicating promising ranges. For instance, previous analyses reveal:

• - 490.00 to 492.00 meters: 32.34 g/t Au and 4.50 g/t Ag over 2.00 meters
• - 536.00 to 552.80 meters: 0.32 g/t Au and 4.20 g/t Ag over 16.80 meters
• - 715.00 to 920.00 meters: Returns 0.25 g/t Au and 1.82 g/t Ag over a length of 205 meters.

These findings counter speculation and demonstrate a strong potential for the recovery of economically viable mineral resources in the area.

Future Steps

Moving ahead, Orvana intends to continue the drilling of TADD-278, with additional depths assessed in line with their targeted goal for this season. Given the early onset of the winter season, no further drilling is scheduled for the current field cycle, but a comprehensive data analysis will be conducted to prepare for the upcoming exploration campaign.

Quality assurance measures in the drilling include rigorous QA/QC protocols, with samples processed under international standards, ensuring that all results are reliable and transparent.

In conclusion, the prospects emerging from Orvana’s exploration at Taguas signal a renewed interest in the region, suggesting potential for significant mineral resource developments in the near future. This campaign, coupled with the professional guidance of industry experts, may abide by the anticipated evolvement within the sector, sustaining economic growth and resource optimization for Orvana and its stakeholders.
