Colossus Resources Resumes Trading and Provides a Corporate Update

________________________________________________________________________

(TSX-V: CLUS) For Immediate Release

Vancouver – June 28, 2023 – Colossus Resources Corp. (“Colossus” or the “Company”) (TSX-V: CLUS) is pleased

to announce that the Company has resumed trading, as of today, June 28th, 2023 and provides a corporate update

on the status of its activities in recent weeks.

First Phase Exploration Drilling Completed at the Master Copper Project, Ontario, Canada

Colossus has completed the first phase of a planned exploration drilling program over targets selected during the

H2 2022 prospecting program, results of which were announced on a corporate News Release dated, January 17,

2023. The current drilling program at the Master Copper project consisted of four (4) relatively shallow, inclined,

diamond core (DDH) holes, totaling 416 metres, covering a 400-metre strike length of fertile vein systems, as seen

on Figure 1 below. Mineralization was observed in all holes (for an example, see Figure 2) and 103 samples have

been collected. The presence of Copper was confirmed in the field using a portable XRF scanner. Samples have

been submitted for assaying and analytical results will be released once available.

and DDH observations.

Figure 2: Semi-massive, brecciated pyrite and chalcopyrite in a quartz vein. In hole MC-23-02, approximately 90m depth

along the hole (drilled inclined at 45 degrees).

Mineralization on the Master Copper property consists of west-northwest oriented quartz or quartz-carbonate

vein sheets, anastomosed or breccia-weld vein systems mineralized with pyrite, chalcopyrite, specularite, and

occasionally bornite, galena and sphalerite. These veins are hosted by Cobalt group sediments consisting of

Gowganda formation conglomerates, siltstones and hematized sandstone, and are common to the North Shore

of Lake Huron, between Sault Ste. Marie and Espanola. As observed on the property, veins often have sharp

contacts, steep dip with a west-northwest strike.

Update on the Transaction for the Acquisition of the Calvario – Mirador Copper Porphyry Projects in Chile

On April 5, 2023, Colossus announced that it has entered into a Letter of Intent (the “LOI”) dated April 4, 2023

with arm’s-length parties Austral Gold Limited and its subsidiaries Minera Mena Chile Ltda and Revelo Resources

Corp. to acquire an undivided 100% interest in the Calvario and Mirador projects in the Republic of Chile (the

“Transaction”). As part of this Transaction, Austral Gold will become the biggest single shareholder of Colossus.

Please refer to the corporate News Release (dated April 5, 2023) for details about the Transaction and the projects.

 Completion of a comprehensive NI 43-101 Technical Compliant Report for the Calvario – Mirador Projects

by independent QPs (see example photo from the report as Figure 3 below). The report is currently under

review by the regulators. Subject to final edits and approvals, it will be filed at Sedar.com in due time.

It must be noted, that till Definitive Agreements have been signed and submitted to TSX-V, the Transaction

remains subject to all applicable regulatory approvals, including acceptance by the TSX-V Exchange.

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 along the prolific Paleocene belt. The exploration

targets within the projects are primarily porphyry Copper (+/- Molybdenum, +/- Gold) fertile systems, located

within large structurally controlled, hydrothermal alteration zones of size (approximately 6.0 km x 1.0 km at

Calvario and 7.0 km x 3.0 km at Mirador). With limited historical exploration work performed till 2015, including

shallow scouting drilling at Calvario, (while Mirador was never tested by drilling), high quality geological,

geophysical and geochemical targets/signatures over the Calvario – Mirador projects, represent an important

strategic land acquisition for the Company.
