Collective Mining Discovers Plutus, a New Major Porphyry Centre Located Five Hundred Metres East of the Apollo Porphyry System

  • Exploration fieldwork has discovered a new porphyry target located five hundred metres east of the high-grade Apollo Porphyry Deposit and referred to as the Plutus Porphyry Centre (“Plutus”).
  • To date, Plutus covers 1,000 metres by 720 metres in area and hosts multiple mineralization styles including porphyry veining, porphyry related breccia mineralization and late-stage carbonate base metal (‘CBM”) veins.
  • Within Plutus are two areas of interest:
    • A 650-metre diameter quartz diorite porphyry which is coincidental with a magnetic high and overprinted by high-grade copper and molybdenum soil anomalies averaging greater than 300 ppm for copper and greater than 30 ppm for molybdenum. The porphyry intrusive hosts areas of vein stockwork which include magnetite and quartz veining plus molybdenite and chalcopyrite.
    • Anchoring the porphyry on its north-western flank are hydrothermal breccia bodies including the previously sparsely drilled Donut Breccia discovery with intercepts from surface including 163 metres @ 1.3 g/t AuEq and 104 metres @ 1.3 g/t AuEq.
  • Reconnaissance rock chip and shallow auger sampling of oxidized (leached) surface material at Plutus has yielded the following results:
    • Gold values up to 4.90 g/t (range of 0.03 g/t to 4.90 g/t);
    • Silver values up to 100 g/t (range of 0.10 g/t to 100 g/t);
    • Copper rock chip values up to 1,482 ppm (56 ppm to 1,482 ppm);
    • Molybdenum rock chip values up to 113 ppm (0.2 ppm to 113 ppm)
  • Drilling is expected to commence at Plutus in August 2023. Four rigs are now operating at the project with eleven holes currently in the lab for analysis.  Additional assay results are expected in the near term from further drilling at Apollo and surrounding targets.

Ari Sussman, Executive Chairman commented: “The Guayabales project continues to demonstrate its remarkable geological endowment. Hard work by the technical team has outlined the Plutus Porphyry Centre, which is the largest target outlined to date at the project. Given the sheer scale of Plutus, three pads are being constructed ahead of drilling which is expected to commence in mid to late August. We will be aggressive in testing Plutus and are hopeful of making another discovery to rival the Apollo porphyry system.”

Toronto, Ontario, July 18, 2023 - Collective Mining Ltd. (TSXV: CNL, OTCQX: CNLMF) (“Collective” or the “Company”) is pleased to announce assay results and field observations from recent reconnaissance exploration work undertaken in the new Plutus Porphyry Centre (“Plutus”), located 500 metres east of the Apollo porphyry system (“Apollo”) at the Guayabales project located in Caldas, Colombia.

Apollo is a high-grade, bulk tonnage copper-silver-gold system, which owes its excellent metal endowment to an older copper-silver and gold porphyry system being overprinted by younger precious metal rich, carbonate base metal vein systems (intermediate sulphidation porphyry veins) within a magmatic, hydrothermal inter-mineral breccia and diorite porphyry bodies currently measuring 455 metres x 395 metres x 915 metres and open for expansion.

This press release outlines results from surface reconnaissance exploration work undertaken at the newly discovered Plutus Porphyry Centre (“Plutus”). Plutus is located 500 metres to the east of the Apollo Porphyry in an area with very sparse outcrop due to landslide and ash cover. Results and observations from Plutus are summarized below.

The Plutus porphyry centre measures 1,000 metres by 720 metres in area and is defined by a large porphyry intrusive in contact with breccia to its north-west. The intrusive body is outlined by soil anomalies of copper, molybdenum, gold, tungsten, tin and bismuth which are coincident with a magnetic susceptibility high. Soil copper values greater than 500 parts per million (“ppm”) and 30 ppm molybdenum with highest values up to 1,482 ppm copper and 127 ppm molybdenum define a 650-metre diameter area outlining the porphyry body. Surface geochemical soil, auger and rock sampling assay results from Plutus displays the following ranges of results:

Rock Chip

  • Gold rock chip values up to 4.90 g/t (range of 0.03 g/t to 4.90 g/t);
  • Silver rock chip values up to 100 g/t (range of 0.10 g/t to 100 g/t);
  • Copper rock chip values up to 1,290 ppm (56 ppm to 1,290 ppm);
  • Molybdenum rock chip values up to 102 ppm (0.2 ppm to 102 ppm).


  • Gold soil values up to 4.80 g/t (range of 0.03 g/t to 4.80 g/t);
  • Silver soil values up to 364 g/t (range of 0.10 g/t to 364 g/t);
  • Copper soil values up to 835 ppm (0.3 ppm to 835 ppm);
  • Molybdenum soil values up to 127 ppm (0.5 ppm to 127 ppm).


  • Gold auger values up to 3.72 g/t (range of 0.03 g/t to 3.72 g/t);
  • Silver auger values up to 56 g/t (range of 0.02 g/t to 56 g/t);
  • Copper auger values up to 1,482 ppm (69 ppm to 1,482 ppm);
  • Molybdenum auger values up to 113 ppm (1 ppm to 113 ppm).

The amount of rock and weathered exposures in the Plutus target area is limited to a few sparse outcrops due to vegetation, historical landslides, and volcanic ash cover.

Observations from surface mapping of the sparse outcrops and logging of auger drilling chips highlights the presence of porphyry-related mineralization, including magnetite veins as well as pyrite, chalcopyrite and molybdenite sulphide and quartz A, B, EB, and D type porphyry veins. The quartz diorite porphyry exhibits both potassic and sericite alteration.

A north-western breccia area with multiple outcrops is located contiguous with the porphyry intrusive body and includes the Donut Breccia discovery where previous drilling intercepts included 163 metres @ 1.3 g/t AuEq from surface in DOC-3 and 104 metres @ 1.3 g/t AuEq from surface in DOC-2 (see press release dated November 15, 2021 and October 18, 2021, respectfully). Follow up work in the breccia area has identified additional outcrops located to the west and east of the area previously drill tested with assay results pending from channel sampling of limited available exposures.

One rig will be mobilized to Plutus with drilling expected to commence in August 2023.

Apollo Drill Program Outline and Assay Update

The 2023 Phase II drilling program is advancing on schedule with 24 holes completed and results announced with an additional eleven holes awaiting assay results from the lab. The objective of the 2023 drilling program is to define high-grade near surface mineralization of the Apollo porphyry system, expand the size of the system through step-out and directional drilling and drill test multiple new targets generated through grassroots exploration. Since the announcement of the discovery hole at Apollo in June 2022, a total of 55 drill holes (approximately 23,907 metres) has been completed and assayed.
