Collective Mining Finds Outcrop on Surface of Main Breccia, Apollo Discovery, Canadian Business Journal

• Recent geological mapping of rocks exposed by the Pad 3 drill access track confirmed that the primary breccia discovery at the Apollo target was sunlit at the surface north and east of the drill pad.
• The recently completed borehole APC-14 was drilled due north from Pad 3 and intersected the main breccia approximately 50 meters below the newly discovered northern outcrop. This hole cut a total of over 240 meters of good mineralization within the main breccia. Analytical results for boreholes APC-11 through APC-14 are expected in the near future.
• Visual observations at the shallower depths of borehole APC-14 show a significant increase in chalcopyrite, leading to potentially higher copper grades than found elsewhere in the main breccia find. Additionally, our belief that the porphyry source of the primary breccia find is due south is now increasing. As a result, preliminary drill holes are now being finalized to test the southern porphyry target.
• The discovery of the northern outcrop of the main breccia combined with sighting observations at borehole APC-14 has extended the strike length of the system by 35 meters to the southwest. As a result, the main breccia finding is now 100 meters wide, 500 meters vertical and 385 meters wide, and remains open in most directions for further extension. As for the eastern outcrop, it is outside the current working model and requires exploratory drilling to determine its shape and how it connects with the main breccia.

TORONTO, September 22, 2022 (GLOBE NEWSWIRE) — Collective Mining Ltd. (TSXV: CNL) (OTCQX: CNLMF) (‘Assemblage’ or ‘Company’), by outcrop mapping and visual observation from shallow diamond drill hole APC-14, the discovery of the primary breccia at the Apollo target (‘Apollo’) is the critical area of ​​sunlight at the surface. We are pleased to announce that we have confirmed that you are bathing in Located to the north and east of Drilling Pad 3 in the southern part of the discovery. Apollo is one of eight targets associated with grassroots-generated porphyry at the Guayabales project in Caldas, Colombia. The primary breccia discovery at Apollo is a high-grade, massive-tonnage copper-gold-silver porphyry-related breccia target with a previously published intercept containing a hole. APC-2 crossed with 207.15 m @ 2.68 g/t AuEq When APC-8, crossed at 265.75 meters @ 2.44 g/t gold equivalent (See press releases dated August 10th and September 13th)^th Respectively). There are currently three of his diamond drill rigs in operation at the Apollo target as part of his 20,000+ meter drilling program, which will be fully funded in 2022.

“Confirmation of the Apollo main breccia discovery extending to the surface enhances the future potential of the project. The fact that we see a significant increase is exciting that porphyry sources are nearby and likely underlie robust, yet untested, high-grade copper deposits. Soil anomaly located to the south As a result, our team has been busy planning exploration drill holes to test porphyry sources and additional details will be provided shortly.

The company recently completed geological mapping of a new outcrop exposure created by a truck designed to service drilling rigs at Apollo’s Pad 3. This work confirmed the exposure of mineralized breccia at the surface as part of the primary breccia discovery first announced by the company on June 22, 2022. The image was recorded from the recently completed diamond hole APC-14, drilled under part of the northern outcrop. It intersects with mineralized breccia starting 50 meters below the surface vertically. Highlights the following observations:

• During the past two weeks, surface exploration teams have identified various outcrops containing mineralized breccia located north of Pad 3. Geological observations in all outcrop areas highlight mineralized cornice breccias containing iron oxides and sulfides within the matrix between clusters with partial sericite overprinting. change. Two historical samples taken from very limited exposures of breccia outcrops within this region contain 0.6 g/t gold, 18 g/t silver, 0.1% copper and 4.1 g/t silver, respectively. t gold, returned 29.3 g/t silver. Recently excavated surface exposures have been systematically sampled and analytical results are pending.
• Visual observations from the recently completed diamond hole APC-14, drilled north from Pad 3, underline part of the northern outcrop region and highlight the presence of angled breccias hosting pyrite. , emphasized the mineralization of chalcopyrite during dissemination. breccia matrix. The hole interrupted mineralized breccia in a second zone starting at 197 meters and ending at about 391 meters downhole from about 84 meters downhole (50 meters vertical) to 132 meters. Analysis of this and other holes is expected in the near future.
• The Apollo target area, as defined to date by limited surface outcrops, rock sampling of CBM veins, available breccia outcroppings, and copper and molybdenum soil geochemistry, is an 800 m X 700 m square. Covers an area of ​​meters. This Apollo target area hosts our new grassroots primary breccia discovery measuring up to 385 meters with a strike length of 100 meters wide and 500 meters vertical based on recent drilling results. The primary breccia finding remains open in most directions, and drill holes continue to confirm and expand the finding. Within the wider targets are additional, as-yet-untested breccia, porphyry, and vein targets that could facilitate further expansion on Apollo.
