Metallis Resources Inc. announced the commencement of the Company's 2022 exploration and drilling program (the "Program") at its 100%-owned Kirkham Property. The Property is situated in the prolific Eskay Camp of the Golden Triangle, northwestern British Columbia, a district known worldwide for the past producing Eskay Creek and Snip gold mines, Seabridge's KSM porphyry deposits, and Newcrest Mining's producing Brucejack gold mine. A targeted and cost-efficient drill program of 3,000 m focused on the South Cliff Area; Re-logging of select holes and drill-core intervals including specific gravity and magnetic susceptibility to help expand upon and test the geologic model; Differential GPS surveying to accurately position all previous drill holes; Field mapping focused on outlining the dimensions of the porphyry intrusions, alteration zones, structures, and morphology of the Cliff-Miles porphyry copper-gold system; and Soil sampling, rock sampling, and selective prospecting over ZTEM™ features that display a signature similar to those associated with the graben at Cliff-Miles and other areas of interest.

The highest Copper ("Cu") and Gold ("Au") grades of the Cliff-Miles trend are hosted by the mineralized Medium-Grained Porphyry (or "MP"), for which the geometry has been determined in a recently developed 3-dimensional (or "3D") geological model. This MP is composed of a tabular feeder (or "trunk") and two sill-like branches that are concentrated to the East of the steeply dipping Adam Fault. Within the MP, the best-mineralized drill intercepts occur in the South Cliff area, with only the upper 150 m being tested to date.

Typically, alkaline porphyry copper/gold systems in the Golden Triangle exhibit a small surface footprint but display increasing grade downward and can continue for more than 1,000 m. The 2022 drilling program has been designed to test for high-grade depth extensions of the MP with a focus on the South Cliff area of the Cliff-Miles trend. The Program will utilize multi-hole drill pads, this is achieved by rotating the drill in the desired direction offering the potential to drill six holes off a single pad. This approach will enable Metallis to achieve efficiencies in both time and effort, whilst keeping a tight control on budget.

Following the successful completion of the drill program, the company anticipates step out holes within the immediate 300 m area to the north as its next focus. The goal of the Company in the near future is to demonstrate the true scale and grade of the system.
