Metallis Begins 2021 Exploration Program at Kirkham Property

VANCOUVER, BC, July 8, 2021 /PRNewswire/ - Metallis Resources Inc. (TSXV: MTS) (OTCQB: MTLFF) (the "Company" or "Metallis") today announces the commencement of the Company's 2021 exploration and drilling program (the "Program") at its 100%-owned Kirkham Property (the "Property"). The Property is situated within the prolific Eskay camp of the Golden Triangle in northwest British Columbia, a fertile metallogenic district known for its precious metal deposits including past producing Eskay Creek and Snip gold mines, Seabridge's KSM porphyry deposits and Pretium's producing Brucejack gold mine.

Metallis' President and CEO Fiore Aliperti stated "Our geological team is set to start an aggressive drill campaign and have been tasked with the goal of expanding the Cliff-Miles porphyry cluster and unlocking the depth potential of bulk tonnage-style copper-gold mineralization." He went on to add, "It is fantastic to be able to throw Metallis' name into the hat with other companies in the Golden Triangle with an active drill program. This program is a major step forward in advancing the Cliff gold-copper porphyry and showing the true size potential of this project."

The Company's geological team has launched detailed field investigations to optimize the placement of the collars in preparation for the drilling, which is due to start in the coming weeks. The Program includes field mapping, drill core re-logging, Induced Polarization ("IP") and a ZTEM™ survey (currently being flown) and is designed to help target the near-surface gold along with the deeper copper/gold-rich potassic zones along the 4 km long Cliff-Miles porphyry corridor.

DRILLING PROGRAM HIGHLIGHTS:

Cliff-Miles Porphyry Corridor

The Company has recently received Re/Os age dates from the Cliff-Miles porphyry (187.2 Ma) confirming that it belongs to the fertile episode of calc-alkalic porphyry intrusions of the Jurassic age Texas Creek Plutonic Suite. This plutonic suite also hosts the nearby Deep Kerr Deposit of Seabridge Gold's KSM project, which has an inferred resource of 1.92 billion tonnes grading 0.41% copper and 0.31 g/t gold, containing 19.0 million ounces of gold and 17.3 billion pounds of copper (Seabridge New Release Feb 16, 2017).

The latest drilling and 3D modelling has highlighted enormous upside potential for the expansion of the Cliff porphyry system. The presence of remnant potassic alteration and improving grades with depth has confirmed the vertical and lateral continuity of copper-gold mineralization as seen in the Red Chris, Deep Kerr, and Saddle North porphyry deposits in the Golden Triangle. A Leapfrog Grade-Shell model demonstrates this grade distribution as currently interpreted (Click Here to View Inclined Grade Shell Leapfrog Model).

Metallis geologists will use surface mapping and sampling, ground IP and airborne ZTEM™ results to vector towards the core zones of the Cliff porphyry system, which have a potential vertical extent of over 1,000m. Leapfrog numeric modeling compiled by Dr. Michelle Campbell and Terraspec vectoring from Dr. Farhad Bouzari have highlighted substantial untested gaps in the Cliff-Miles porphyry corridor. Metallis' V.P. of Geoscience Services, Dr. Razique stated "We now have a robust 3D model of the Cliff-Miles porphyry corridor which has highlighted 3 major blocks, each of which show significant volume potential of high-grade copper-gold mineralization to be tested this year."

About the Kirkham Property

The wholly owned 106 sq. km Kirkham Property is located about 65 km north of Stewart, B.C., in the heart of the Golden Triangle's prolific Eskay Camp. The Property is prospective for multiple mineral deposit types and is located along a strategic geological boundary – the "Red-line" exposed on the western margin of the Eskay Rift system in the Golden Triangle, northwestern British Columbia.

The Kirkham Property is contiguous to Garibaldi Resources' E&L Nickel Mountain Project in the north and Eskay Mining Corp. to the east. The property is within 12 km of the Eskay Creek mine while the eastern border is within 12 - 20 km of Seabridge Gold's KSM deposits and Pretium Resources' Brucejack mine.
