Ari Sussman, Executive Chairman commented: “Our directional drill program is off to an excellent start by demonstrating that orthogonal drilling improves the grade profile locally due to an abundance of zones flooded with mineralized CBM vein fluid. Additionally, directional drilling is making it much easier for the Company to test and expand the Apollo envelope by allowing the Company to quickly reach areas that are not possible to drill from surface due to topography. Visual observations of holes APC70-D5 (Pad 1) and APC88-D1 (Pad 14) notes intercepts of more than 500 metres (APC70-D5) and 500 metres plus a second zone of more than 200 metres (APC-88-D1) indicating that a potential material size increase to the envelope of the system will be forthcoming upon receipt of assays in early Q1, 2024.”
Collective Mining Ltd. (TSX: CNL) (OTCQX: CNLMF) is pleased to announce assay results from the first four directional drill holes into the Apollo porphyry system. Apollo hosts an outcropping high-grade, bulk tonnage gold-silver-copper-tungsten porphyry system measuring 520 metres x 395 metres x 935 metres (previously 915 metres) which remains open for further expansion. Presently there are four diamond drill rigs operating at the Guayabales project as part of the Company’s planned 42,000 metre drilling program for 2023.
Details (See Table 1 and Figures 1-5)
This press release outlines the first results from the mother hole (APC-70) and four directional holes (APC70-D1 to D4) drilled from the end of the mother hole and designed to test for grade continuity at depth as well as western extensions to the Apollo porphyry system. APC-70 was drilled due south from Pad 1 and its directional holes form a fan pattern from southeast to southwest, intersecting the Apollo system more perpendicularly than prior drilling.
APC-70 was the mother hole for this first directional program and was drilled steeply to the south from Pad 1 to a final downhole depth of 293.30 metres. The principal objective of this hole was to reach the optimal depth to commence the directional drillholes. The hole intersected shallow mineralization related to carbonate and base metal veining at 83.30 metres downhole for 22.70 metres with assays results as follows:
APC70-D1 was the first deflection from the mother hole and was drilled due south to a final directional downhole depth of 624.10 metres (745 metres vertical from surface due to depth of mother hole). The hole entered brecciated porphyry at 229.30 metres downhole and continued in mineralization for 199.40 metres. The mineralized breccia zone consists of a sulphide matrix cement hosting chalcopyrite (up to 0.4%), pyrite (up to 1.6%) and pyrrhotite (up to 0.8%) as well as later and overprinting CBM vein sulphides such as sphalerite (up to 0.8%), galena (up to 0.3%) and trace amounts of fine, free gold with assay results as follows:
APC70-D1 encountered better grades than previously modelled in this area from drill holes APC-17 and APC-49 and as a result will improve the grade block model in this location. Directional drilling perpendicular to the breccia body has also identified multiple zones of sheeted CBM veins which were intersected from downhole depths of 229.30 metres, 281.40 metres and 402.2 metres over intersection lengths ranging from 22.3 metres to 32.90 metres with grades between 2.32 g/t gold equivalent to 3.48 g/t gold equivalent.
APC70-D2 was drilled in a southeast direction from the mother hole to a maximum downhole deflection depth of 501.80 metres (625 metres vertical from surface due to depth of mother hole). The hole encountered sheeted CBM vein zones at 15.00 metres and 181.40 metres downhole depths for intervals of 11.70 metres and 5.90 metres, with grades of 1.52 g/t gold equivalent and 1.78 g/t gold equivalent, respectively. The hole entered brecciated porphyry at 213.10 metres depth and intersected 168.20 metres of mineralization consisting of a sulphide cement matrix hosting chalcopyrite (up to 0.3%), pyrite (up to 1.5%) and pyrrhotite (up to 1.0%) with CBM vein sulphides such as sphalerite (up to 0.3%) and galena (up to 0.2%). The following assay results are highlighted:
APC70-D2 also encountered better grades than previously modelled in this area due to the presence of multiple zones hosting sheeted CBM veins (see Table 1) and as a result will improve upon the grade block model in this location.
APC70-D3 was drilled southwest to a maximum directional depth of 481.10 metres (654 metres vertical from surface due depth of mother hole). At the beginning of the hole, sheeted CBM vein mineralization was intersected over intervals between 5.10 metres and 28.45 metres with grades of up to 3.33 g/t gold equivalent. Beginning at 245 metres downhole, brecciated porphyry mineralization was intercepted over a total of 168.80 metres. The sulphide mineralization in the breccia matrix in this interval consists of chalcopyrite (up to 0.3%), pyrite (up to 1.1%), sphalerite (up to 0.6%), galena (up to 0.8%) and pyrrhotite (up to 1.5%). The following assay results are highlighted:
The APC70-D3 intercept has extended the Apollo system locally for a further 25 metres to the southwest into an area with no previous drilling. Furthermore, the hole bottomed in mineralization with the final 4.7 metres grading 1.4 g/t gold equivalent, opening the opportunity for further mineralization extensions in this area.
APC70-D4 was drilled southwest to a maximum directional downhole depth of 728.25 metres (935 metres vertical from surface due to depth of mother hole). APC70-D4 is the deepest hole drilled to date at Apollo, reaching depths of 935 metres below surface (1,075 RL).
From 45.25 metres to 197.80 meters the hole encountered a series of sheeted CBM vein intervals hosted within quartz diorite porphyry. Beginning at 268.55 metres downhole, the hole intersected 389.45 metres of brecciated porphyry mineralization with sulphide matrix cement hosting chalcopyrite (up to 0.2%), pyrite (up to 3.0%), sphalerite (up to 0.5%), galena (up to 0.2%) and pyrrhotite (up to 1.3%). The following assay results are highlighted:
The results of directional hole APC70-D4 confirm the discovery of a 100-metre southwest depth extension to the Apollo Porphyry system. Apollo remains open to the west for further expansion and recent visual logging of new, westerly directed, directional hole APC70-D5 has confirmed the discovery of over 500 metres of brecciated porphyry mineralization in this area.
Exploration Drill Program and Assay Update
Diamond drilling at the Guayabales project currently totals 128 drill holes (approximately 51,380 meters) completed and assayed. The 2023 Phase II drilling program is advancing on schedule with assay results reported for 57 holes and an additional ten holes awaiting assay results from the laboratory.
With four diamond drill rigs now operating at site, the Company is advancing with the following objectives:
The Apollo area, as defined to date by surface mapping, rock sampling and copper and molybdenum soil geochemistry covers a 1,000 metres X 1,200 metres area and represents a large and unusually high-grade gold-silver-copper tungsten porphyry system. Mineralization styles include early-stage porphyry veins, inter-mineral brecciated porphyry mineralization and multiple zones of late stage, sheeted, carbonate-base metal veins with high gold and silver grades. The Apollo area is still expanding as the Company’s geologists have found multiple additional outcrop areas with porphyry veining, breccia, and late stage, sheeted, carbonate base metal veins.

**AuEq (g/t) is calculated as follows: (Au (g/t) x 0.97) + (Ag (g/t) x 0.016 x 0.88) + (Cu (%) x 1.79 x 0.90)+ (Mo (%)*11.62 x 0.85) + (WO3 (%)*6.54 x 0.50) utilizing metal prices of Cu – US$3.85/lb, Ag – US$24/oz Mo – US$25/lb, WO3 – US$31,000/t and Au – US$1,475/oz and recovery rates of 97% for Au, 88% for Ag, 85% for Mo, 50% for WO3 and 90% for Cu. Recovery rate assumptions for gold are based on metallurgical results announced on October 17, 2023. Recovery rates for copper, molybdenum, tungsten and silver are speculative as limited metallurgical work has been completed to date on these metals. True widths are unknown, and grades are uncut. All depths outlined in directional holes are from commencement of kick off point in the mother hole. |
