Minaurum Drills 3.1 m of 1197 g/t Silver (42 opt) in Promontorio Zone at the Alamos Silver Project






Minaurum Gold, Inc (TSX-V: MGG) is pleased to announce exceptional grades over substantial widths from three of its first four holes targeting the Promontorio vein zone at its Alamos Silver Project in Sonora, Mexico. The holes were targeted below the historical Promontorio mine and demonstrate that high-grade silver mineralization continues at least 100 m below the deepest known workings. Significant highlights include:


  • 5.1 m of 769 g/t Ag, 0.76% Cu; incl. 3.1 m of 1,197 g/t Ag, 1.38% Cu in hole AL20-046
  • 2.9 m of 636 g/t Ag, 1.36% Cu, 3.85% Pb, 7.18% Zn in hole AL20-044
  • 1.75 m of 144 g/t Ag, 4.15% Pb, 9.10% Zn in hole AL20-043


“We are very pleased by these high-grade silver results from the Promontorio Vein, historically the second largest producer at Alamos. These results confirm that mining stopped in mineralization and that it continues to depth,” stated Darrell Rader, President and CEO of Minaurum. “We are continuing to trace the mineralized shoot through systematic 75- to 150-metre step-outs along strike and down-dip.”


Assay highlights are presented in Table 1. Vein and hole locations appear in Figures 1 and 2. The holes and intercepts are depicted in longitudinal section in Figure 3. Drilling at Promontorio continues and results will be released as they are received.


Promontorio Zone


The Promontorio vein zone has become one of Minaurum’s highest priority targets, in part because of historic reports acquired earlier this year (see News Release dated February 6th, 2020) showing that the Promontorio Mining Company ceased operations in 1896 due to a drop in the silver price and left the faces in mineralization. The company exploited three principal veins, Veta Guijas, Veta Grande, and Veta del 100, which were mined to a depth of 230 m along 735 m of strike length. Mining focused on high-grading the veins with little effort spent on development, which explains the considerable amount of un-mined mineralization left behind in the workings.


Holes AL20-043 and AL20-046 intersected mineralization below the Promontorio workings. AL20-044 intersected the Promontorio vein zone roughly 100 m down-dip from the intersection in AL20-043 and AL20-048 cut the vein zone about 100 m below AL20-046.


Table 1. Assay highlights from holes AL20-043, AL20-044, AL20-046, and AL20-048 drilled on Promontorio vein zone. Hole depths in metres. True thicknesses of the intersections are estimated to be 70-90% of drilled thicknesses.
