Capitan Mining Announces Drill Results from Peñoles Project: Expands Gold Mineralization to Southwest and Southeast






Capitan Mining Inc. (TSX-V: CAPT) is pleased to report results from eight drill holes from its 2021 program on the Capitan gold zone.


  • Hole 21-CARC-24 returned 10.7m @ 0.56 g/t Aueq within a larger interval of 42.7m @ 0.34 g/t Aueq
  • All reported drill holes herein returned Capitan style mineralization, over significant width’s
  • To date the Capitan gold zone has been traced for 1.2 kilometres along strike and up to 450 metres down-dip and remains open in all directions except to the north.
  • These drill holes, complete the previously announced 6,000 metres drill campaign; consisting of 28 Reverse Circulation (RC) holes, all of which hit dominantly oxide gold mineralization
  • Drilling activities remain ongoing with updated guidance to be released in the coming days


Holes 21-CARC-21 to 28 Discussion

The purpose of these drillholes was threefold:

  1. To define and expand known, near surface mineralization in the Hanging wall zone and locate new zones of mineralization in step-outs towards the southwest
  2. To expand and better define the on-strike extensions of the known mineralized zones outside of the current drill defined area
  3. To delineate the extents of high-grade ore shoots in the Main Capitan zone


Eastern holes: 21-CARC-21, 22, 25 and 28

Holes 21-CARC-21,22, 25 and 28 were collared in the eastern portion of Capitan Deposit area, in a region with very sparse drilling and surface exploration (see Figure 1). The holes were designed to target the down-dip and on-strike extensions of the Hanging Wall Zone, that was intersected in holes 20-CARC-15 and 18 as well as in historic core holes CDDH-08-03 and CDDH-11-10. All holes successfully intersected multiple, low grades zones of Hanging wall stylemineralization, with the best intercepts including 21.3m of 0.19 g/t Au eq in hole 21-CARC-21, 25.9m of 0.19 g/t Aueqin hole 21-CARC-25 and 45.7m of 0.15 g/t Aueq in hole 21-CARC-28. Additionally, the drillholes successfully extended the on-strike extent of the Capitan Hill deposit, in this area, by 125m to the east, and the down-dip extent between 75m and 150m respectively. Based on the location and results returned from the holes above, it is interpreted that holes 21-CARC-21, 22, and 28 were drilled well below the main ore shoot that was being targeted, with hole 21-CARC-28 intersecting the zone slightly up-dip from the main ore shoot.

Discussion: Holes 21-CARC-23, 24, 26 and 27 

Drillholes 21-CARC-23 and 27 were collared within the east-central portion of the Capitan Main target area and were designed to test the down-dip extension of the main Capitan Hill zone on sections 50 and 000 respectively. Hole 21-CARC-23 ran into technical issues after intersecting the Hanging wall zone. The hole returned multiple, low grade values, including 13.7m of 0.29 g/t Aueq before being terminated prior to the Capitan Main zone. Hole 21-CARC-27 was a large (150m) step-out from hole 20-CARC-17 (see Figure 2) and returned multiple, low-grade intervals   for most of its length. The most significant intersections include 45.7m of 0.21 g/t Aueq and 18.3m of 0.21 g/t Au.

Holes 21-CARC-24 and 26 were designed as large (80m and 130m respectively), on section step-outs, in order to extend the Capitan Main and Hanging wall zones down-dip, as well as identify new, shallow zones of mineralization developing in the hanging wall of the deposits. Both holes successfully intersected their respective targets, with each returning multiple intervals of low-grade Hanging wall style mineralization in the upper portions of the hole, over significant widths, and intervals and grades more typical of Capitan style mineralization in the lower portions. The most significant intersections include 10.7m of 0.56 g/t Aueq in hole 21-CARC-24 and 111.3m of 0.17g/t Aueq and 33.5 m of 0.37 g/t Aueq in hole 21-CARC-26. Although both holes successfully intersected their respective targets, it is interpreted that both holes were drilled along either the upper (21-CARC-24) and lower (21-CARC-26) margins of the main ore shoot.




Capitan’s CEO, Alberto Orozco, stated: “I’m pleased to report that all of our reported drill holes to date have intersected gold mineralization, highlighting the significant scale of the mineralized system at our Peñoles project. We are well underway to expanding the mineralization from the existing inferred resource at Peñoles with mineralization remaining open in most directions and at depth. With our recently announced private placement completed, Capitan Mining is fully funded for the next year.”
