Intersected Mineralization From Exploratory Drilling At Promontory Sur

VANCOUVER – Minaurum Gold Inc. reported the Promontorio Sur vein zone at its Alamos Silver Project (“Alamos”) in Sonora, Mexico. The 1.5 km-long Promontorio Sur vein zone represents the unmined southern continuation of the recently identified high-grade Promontorio “stacked” vein zone. It is separated by a northwest trending, steeply southwest dipping fault that cuts four separate substantial vein structures, including the Las Guijas vein zone where the widest high-grade intercept drilled at Alamos returned 36.65 m of 328 g/t silver equivalent ‘AgEq’ (AL24-117) at Alamos.

Exploratory drilling at Promontorio Sur has intersected mineralization typically seen at high levels of the Alamos vein system, indicating that high grade mineralization should be found at depth. Results include 1.05 m of 272 g/t AgEq, which included 0.20 m of 617 g/t AgEq (304 g/t Ag) and 2.65 m of 142 g/t AgEq, including 0.45 m of 300 g/t AgEq and a gold grade of 3.26 g/t Au (AL19-020), followed by a wide interval of CRD replacement-type mineralization including 4.95-m of 174 g/t AgEq that included 0.45 m of 536 g/t AgEq (5.41% Pb and 12.85% Zn).

”The Promontorio Sur vein zone presents a compelling opportunity to unlock a previously untapped section of the highest-grade stacked vein system within the Alamos Project. This prolific vein system hosts the historic Promontorio Mine, which has produced over 70 million ounces of silver, as well as the nearby La Quintera Mine—just 1 km to the north—which is estimated to have yielded an impressive 100 million ounces of silver. With 1.5 km of known strike length, Promontorio Sur represents one of the largest, virgin exploration targets at the Alamos Silver project,” stated Darrell Rader, President and CEO.

Promontorio Sur is the southernmost segment of the 3.5 km-long Promontorio-Quintera structural trend. The Promontorio-Quintera trend and its and hosted veins are cut by a northwest-striking, steeply southwest-dipping fault that cuts the high-grade Las Guijas vein. Displacement of the faulted-off portion of Las Guijas is estimated to be at least 200 m, with the southwestern side of the fault, including the Promontorio Sur zone, down-dropped relative to the northeastern side of the fault. Horizontal displacement appears to be in the order of tens of metres.

The Promontorio Sur vein zone can be traced on surface for 1.5 km as quartz-carbonate veinlets hosted in andesitic agglomerate. The veinlets are interpreted as representing high levels of the epithermal system, with potential for high-grade mineralization at depth. Outcrop geochemical sampling shows anomalous values of silver, gold, and base metals along the structure. Minaurum drilling shows that the andesite overlies altered and mineralized limestone, with mineralization occurring at a fault contact between volcanic rocks and limestone, as well as skarn and replacement-type mineralization within altered limestone.

Drilling to date at Promontorio and Promontorio Sur also indicates a significant skarn/carbonate replacement (CRD) mineralization hosted by limestone in the footwall of the vein zones. The lead-zinc (gold) skarn/CRD event appears to have occurred later than the epithermal silver-copper mineralization and represents a large target.
Further exploration of the Promontorio Sur zone will focus on drilling the faulted-off portion of the Promontorio zone, Las Guijas vein as well as drilling under the area of the anomalous rock geochemistry.
