Mining Stock News: Colossus Resources (TSXV: CLUS) Signs Definitive Agreement with Austral Gold Limited to Acquire the Calvario and Mirador Copper Porphyry Projects in Chile


Vancouver, British Columbia - November 16, 2023 (Newsfile Corp.) ( Newswire) Colossus Resources Corp. (TSXV: CLUS) ("Colossus" or the "Company") is pleased to announce it has entered into a definitive Option Agreement (the "Option Agreement") dated November 15, 2023 with arm's-length parties Austral Gold Limited and its subsidiaries Minera Mena Chile Ltda and Revelo Resources Ltd. (collectively the "Austral Group") to acquire an undivided 100% interest in the Calvario and Mirador projects in the Republic of Chile. The transaction is subject to all applicable regulatory approvals, including acceptance by the TSXV and, if required, shareholder approval.

The Calvario and Mirador properties (the "Projects") are currently 100% owned by the Austral Group which holds the rights to the exploration and exploitation concessions divided into 59 "mensuras" (exploitation mining properties) covering a total area of 14,674 hectares. The Projects are located approximately 80 km northeast of the coastal city of La Serena in the 4th Region of Coquimbo of central-northern Chile in South America. The Coquimbo deep sea shipping port is situated approximately 160 km southeast of the Projects.

The exploration targets within the Projects are primarily porphyry copper (+/- Molybdenum, +/- Gold) systems. The Projects lie along the southern extensions of the highly productive Paleocene magmatic belt of northern Chile that hosts some of the most important copper and precious metals deposits in the country, such as Spence and Cerro Colorado (BHP), Sierra Gorda (KGHM) and Relincho/Nueva Reunion (Teck-Newmont Goldcorp). The Calvario and Mirador projects comprise an important strategic land position with multiple copper targets controlled by the same regional thrust faults. The Projects are located approximately 115 km south of the 50-50 Teck - Newmont Goldcorp's Relincho/Nueva Reunion Joint Venture advanced Project, one of the largest undeveloped copper-gold-molybdemum projects in the Americas.

Colossus' technical Director Ioannis (Yannis) Tsitos states: "The successful conclusion of the Definitive Agreement for the acquisition of the Calvario and Mirador Projects in Chile signifies an important milestone for Colossus. With this acquisition, Colossus Resources secures a significant and strategic mineral rights position in one of the most prospective belts, still underexplored, of central-northern Chile associated with significant copper and precious metals mineralization. Subject to the necessary approval of the transaction by the regulatory authorities, Colossus is looking forward to work closely with the Austral Group (which as a product of this transaction, will become the single biggest shareholder of the Company) and its experienced technical team to advance both Calvario and Mirador projects towards a major copper (± Mo ± Au) discovery. Although Calvario is a drill-stage ready exploration project based on historical data, both Projects have not seen any exploration activities in the last decade. Nevertheless, they exhibit important technical facts on the presence of large hydrothermal alteration systems in addition to on-surface and near-surface copper mineralization, possibly associated with untested hypogene parts of fertile porphyry systems."

Terms of the Acquisition

Terms of the Agreement provide for funding by the Company of not less than USD$2.5 million in exploration expenditures on the Projects over a period of two years, of which at least USD$1.5 million must be incurred in the first 18 months. The Company will also issue to Minera Mena Chile Ltda (a wholly owned subsidiary of Austral Gold Limited) or its nominee, such number of common shares in the capital of Colossus ("Colossus Shares") as to be equal to 19.9% of the post-issuance Colossus Shares outstanding, and one million share purchase warrants, each of which shall entitle the holder to purchase one Colossus Share for an exercise price of C$0.50 for three years.

The Company paid the sum of USD$100,000.00 to Austral Gold Limited as an exclusivity fee, which funds were used by Austral to pay the 2023 maintenance cost (canon fees) of the Projects.

The Projects are subject to net smelter return royalties over base and precious metals, of which Minera Mena Chile Ltda will retain the right to purchase half the royalties.

About the Calvario and Mirador Projects (the "Projects")

The Calvario and Mirador projects are located approximately 80 km northeast of the coastal city of La Serena in the Coquimbo Region of central-northern Chile in South America. The exploration targets within the Projects are primarily porphyry copper (+/- Molybdenum, +/- Gold) systems. The Projects lie along the southern extensions of the highly productive Paleocene magmatic belt of northern Chile. Together they form a contiguous 23km x 8km set of properties as follows (see Figure 1):

  • The Calvario Project consists of 28 titles (Title type: Exploitation) covering 6,870 hectares. A portion of the Calvario Project (2,200 hectares) are subject to a 2% base metals Net Smelter Royalty ("NSR") and an 1% precious metals NSR in favour of Mineral Global Copper Chile S.A., a wholly owned subsidiary of the major royalties corporation, Franco Nevada Corporation (Canada). The balance of the Calvario titles (4,470 hectares) are free of any royalties.
  • The Mirador Project consists of 31 titles (Title Type: Exploitation) covering 7,744 hectares. Ten of the Mirador titles (covering 2,400 hectares) are subject to a 2% base metals NSR and an 1% precious metals NSR in favour of Mineral Global Copper Chile S.A. Nineteen of the other Mirador titles (covering 4,744 hectares) are subject to a 2% base metals NSR and an 1% precious metals NSR in favour of Sumitomo Metals Mining Chile Ltda., a wholly owned subsidiary of the major mining corporation, Sumitomo Metals Mining Co. (Japan). Two titles (covering the balance 600 hectares) are free of any royalties.

Calvario is a porphyry copper (± Mo ± Au) system characterised by a structurally controlled quartz-sericite alteration zone oriented NNW-SSE some 6.0 km x 1.0 km in size, hosted within monzonite and quartz-feldspar porphyry intrusions and other rocks. Relict sulphides (pyrite and chalcopyrite) in the leached and oxidised surface exposures, minor copper oxides (see Figure 2) and associated Mo (>10 ppm) and Cu (>600 ppm) geochemical anomalies in soils and talus fines samples, together with stockwork quartz D-type veins have defined a principal target area around 1,500 m x 700 m in size at the southern end of the alteration zone, which may reflect a possible hypogene copper target at depth. Two secondary targets occur further to the north along the principal alteration zone mapped. The priority target area coincides with three of the six relatively shallow historic diamond drill holes drilled by Minera Fuego Ltda (now Mineral Global Copper S.A.) in 2008. They display moderate quartz-sericite alteration with minor copper oxides as coatings on pyrite and in fractures, and minor chalcocite mineralization indicating weak secondary enrichment. Best intersections include Hole# FCAR-07 reporting 92m @ 0.23% CuT (Total Copper) & 21 ppm MoT (Total Molybdenum), including 20m @ 0.54% CuT & 24 ppm MoT and Hole # FCAR-14 reporting 62m @ 0.20% CuT & 22 ppm MoT, including 28m @ 0.30% CuT & 20 ppm MoT. Information from surface exposures and drill holes suggests that erosional levels are not sufficiently deep to have produced significant secondary enrichment, with essentially relatively high-level phyllic alteration exposed at surface. Hypogene copper mineralisation has not been specifically targeted by the limited historical drilling, and comprises the target for future drill testing. The property has been structurally uplifted by a series of regional thrust faults related to the San Felix - Vicuña fault system.

Exploration activities to date have included geological mapping of outcropping areas, alteration mapping, mineralogical studies, limited rock-chip surface sampling, limited ground magnetics and relatively shallow drill testing (4,314m of drilling in 20 holes, mostly shallow Reverse Circulation) of certain targets. No work has been done over Calvario in recent years.

The property is easily accessed, being located close to the recently paved highway that connects the main paved Pan-American Highway, through Tres Cruces, to the Pascua-Lama project (Barrick Gold). A short, well maintained dirt road links the project to the paved highway. A new high-tension power line has been installed along the Pascua-Lama highway. The project is located at altitudes ranging from about 3,000m to 3,300m.

Although Calvario is a drill-stage ready exploration project, the Company believes that some complementary geochemistry and geophysical surveys should be conducted in order to vector to the most productive parts of the porphyry system/s, prior to any drilling, to commence in H1 2024. A current NI 43-101 compliant technical report covering both the Calvario and Mirador Projects has been produced for Colossus and will be filed with the regulators as part of the necessary approval of this transaction by TSX-V.

Mirador is a porphyry copper (± Mo ± Au) and high-sulphidation epithermal copper-gold exploration target and it is the southernmost of the two (with Calvario) large hydrothermal alteration systems located within the Properties. Mirador also lies along the same highly productive Paleocene belt of Chile.

The Mirador project and identified targets within its titles, have never been drilled to date!

Mirador represents a porphyry copper (± Mo ± Au) system, currently exposed at the upper-porphyry to epithermal levels (see figure 3), probably representing the base of a lithocap overlying the proposed porphyry copper target(s). Potential for high-sulphidation, epithermal copper-gold also exists. Extensive quartz-sericite and argillic alteration characterise the northern sector of the alteration zone.

Figure 3: Outcrop of rocks affected by intense argillic alteration and veinlets of types C and D at Mirador, typical of feltile copper porphyry systems.

The alteration area (see Figure 4) extends over more than 7.0 x 3.0 Km, with superimposed advanced argillic alteration dominated by quartz-alunite in the central and southern sectors. Intense hydrothermal alteration is hosted principally within dacitic rocks. Phreatic breccias have been recognised, also suggesting the upper portions of a porphyry copper system. Surface outcrops are intensely leached. Limited copper oxides coincident with fine quartz veinlets at lower elevations to the north, suggest proximity to porphyry copper levels. Multi-element geochemical anomalies in rocks (Mo-Cu-Bi-Au - with Mo >24 ppm to 153 ppm, and Cu >92 ppm to 500 ppm) suggest porphyry copper potential in the northern and possibly southern portions of the alteration zone, while the central areas (As-Sb geochemistry) more closely suggests a high-sulphidation epithermal environment with potential for copper-gold mineralisation and possibly gold and silver. The property has been structurally uplifted by a series of regional thrust faults related to the San Felix - Vicuña fault system. Mirador together with contiguous Calvario project, form an important pair of copper targets controlled by the same regional thrust faults.

Exploration activities to date have included detailed geological mapping of outcropping areas, detailed mapping of alteration mineralogy, and minor geochemical sampling of rocks. Further detailed alteration mapping and geochemical sampling to aid vectorisation towards potential productive levels, supported by geophysical testing (magnetics and IP), is required prior to drill testing of the principal targets.


The Company also announces a non-brokered private placement financing of up to 15,000,000 units (the "Units") of securities at a price of $0.16 per Unit for aggregate gross proceeds of up to $2,400,000.00 (the "Financing"). Each Unit will be comprised of one (1) common share and one-half of one (1/2) non-transferable common share purchase warrant, with each whole warrant entitling the holder to purchase one additional common share at a price of $0.30 for a period of two (2) years from closing of the Financing.

The Financing will be completed in tranches, with the first tranche of $250,000 to be used for working capital. The balance of the Financing will be completed concurrently with receipt of TSXV final acceptance of the Option Agreement and the transactions contemplated thereby, and will be used to advance the Company's exploration program on the Projects.

All securities issued under the Financing will be subject to a four month hold period. Finders fees may be payable on all or a portion of the Financing.
