AbraSilver Resource Corp. reported new diamond drilling results from Phase VI of exploration at the Diablillos project, located in Salta, near the border with Catamarca. The drill holes confirmed the continuity of gold and silver mineralisation within the planned Oculto open pit and extended the gold-mineralised zone towards Oculto East.

The results relate to drill holes DDH-26-064 and DDH-26-063A, whose assay data will be incorporated into the next mineral resource update, scheduled for the second quarter of 2027.
Results at Oculto
Drill hole DDH-26-064, completed within the planned Oculto open pit, intersected 75 metres grading 2.44 grams per tonne (g/t) gold and 106 g/t silver, starting at a downhole depth of 220 metres.
The interval included 8 metres grading 5.94 g/t gold and 7 metres grading 7.97 g/t gold. A separate 5-metre interval grading 556 g/t silver was also identified, starting at a depth of 158 metres.
At greater depth, drilling returned 16.5 metres grading 1.50 g/t gold, 11 g/t silver and 0.44% copper, associated with sulphide mineralisation.
According to AbraSilver, the results support the continuity of the higher-grade mineralised zones incorporated into the current Oculto mine design.
Extension Towards Oculto East
Drill hole DDH-26-063A, completed along the eastern margin of the deposit, intersected 253 metres grading 0.54 g/t gold and approximately 10 g/t silver, including 4 metres grading 2.24 g/t gold.
Much of this interval lies beneath the current pit design and extends oxide gold mineralisation eastwards from the structure known as Cross Breccia.
These results follow those from drill hole DDH-26-061, reported in October, which returned 228 metres grading 1.79 g/t gold, including 66 metres grading 4.04 g/t.
AbraSilver will continue drilling to determine the extent and continuity of mineralisation between these areas and its relationship to the existing mineral resources.
Next Steps for the Project
John Miniotis, President and CEO of AbraSilver, stated that the new results provide additional information for the resource model and help identify further exploration targets.
The company currently has three active drill rigs and expects to complete Phase VI before the end of 2026. It has also completed a controlled-source audio-frequency magnetotelluric (CSAMT) geophysical survey, with the results now being interpreted to guide future drilling.
The mineral resource update is scheduled for the second quarter of 2027.
In parallel, AbraSilver has indicated that it expects to publish a preliminary economic assessment of heap leaching and maintains its target of making a final construction decision during the same quarter.
Diablillos has a Definitive Feasibility Study completed in June 2026. According to the company, its proven and probable reserves total 77.9 million tonnes, containing an estimated 184 million ounces of silver and 1.8 million ounces of gold.
