Collective Mining Ltd. (TSXV: CNL) (“Collective” or the “Company”) is pleased to provide an exploration update from its Olympus target (“Olympus”) within the Guayabales Project, located in Caldas, Colombia. The Guayabales project is situated contiguous, immediately along strike and to the northwest of Aris Gold’s Marmato gold mine, which contains proven and probable reserves of 2.0 million ounces gold and 4.35 million ounces silver (19.7 Mt grading 3.2 gt gold and 6.9 gt silver). The Company interprets the abundant precious metal mineralization encountered throughout the Guayabales Project to be related to multiple mineralized styles that include gold-copper-molybdenum porphyries and associated breccia as well as high grade, precious and base metal vein systems that are superimposed on and enrich the porphyry bodies.
“We are very excited about the Olympus target due to its multiple mineralization styles and enrichment of porphyry mineralization by a high-grade vein overprint. Although underground exposures to channel sample were limited due to extensive small-scale mining-related historical timber support, significant high-grades of both gold and silver were encountered over an area measuring 600 x 600 metres with mineralization remaining open in all directions. Work to date at Olympus clearly indicates that there will be multiple targets ready for drill testing in the near future,” commented Ari Sussman, Executive Chairman.
Highlights (Table 1 and Figures 1-4)
The Company has received results from shallow underground channel sampling at its Olympus target within the Guayabales Project. The Olympus target is a NW trending mineralized corridor located in a porphyry intrusive. Gold and silver mineralization is hosted within multiple styles that include high grade vein, porphyry veinlet, breccia and disseminated systems.
- Ten old mine adits have been sampled to date with assay results for the initial six adits reported herein. In all cases, channel sampling was limited to infrequent underground exposures which were not covered by historical post-mining timber support with highlight results as follows:
- 46.5 g/t gold equivalent over 1 metre (19.1 g/t Au and 1,919 g/t Ag);
- 39.0 g/t gold equivalent over 2.7 metres (33 g/t Au and 421 g/t Ag);
- 16.3 g/t gold equivalent over 1 metre (9.7 g/t Au and 464 g/t Ag);
- 20.8 g/t gold equivalent over 0.9 metre (20.7 g/t Au and 9 g/t Ag);
- 13.8 g/t gold equivalent over 1.7 metres (9.3 g/t Au and 314 g/t Ag) and;
- 11.8 g/t gold equivalent over 1 metre (6.1 g/t Au and 399 g/t Ag).
- Porphyry A and B veinlets in sheeted and stockwork zones and associated with disseminated sulphides returned 19 values ranging from 4.7 g/t AuEq to 1.1 g/t AuEq from widths of 2.0 metres to 0.3 metres in available underground exposures. This lower grade mineralization has been overprinted by the high-grade veins.
- The southernmost workings in the target area returned 8.6 g/t AuEq and 8.2 g/t AuEq from a mineralized breccia zone with clasts and matrix of massive sulphide material.
- The Olympus mineralized corridor has been mapped over a width of 600 metres and a NW strike of 600 metres. The target is open in all directions. The 600 metres wide corridor hosts 41 shallow underground adits.
- Underground sampling and surface mapping continues at the Olympus target area.
