Metallis Completes Phase 1 Field Program and Readies Team for Aggressive Drilling

VANCOUVER, Aug. 11, 2020 - Metallis Resources Inc. (TSXV: MTS) (OTCQB: MTLFF) (FSE: 0CVM) (the "Company" or "Metallis") announces the completion of the Company's Phase 1 - 2020 Field 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 district known for the past producing Eskay Creek and Snip gold mines, Seabridge's KSM porphyry deposits and Pretium's Brucejack gold mine.

The Program, which included extensive field mapping, drill core re-logging and short-wave-length infrared ("SWIR") analysis was successfully executed with all key objectives achieved. All data is being compiled, analyzed and reviewed through a series of collaborative meetings expected to take about a week. These sessions will assist the geological team in identifying drill targets for the upcoming Phase 2 Program at the Cole and Cliff high-grade gold/porphyry systems and the K9 nickel prospect, which is due to commence imminently.

The detailed Induced Polarization Survey ("IP Survey"), previously announced as part of the Phase 1 Program (See News Release July 15, 2020), over multiple targets (Cole, Cliff, King East and K9) by Scott Geophysics Ltd is now over 50% complete. Contingencies established prior to the launch of the IP Survey have ensured that it's finish date will not impact the start date of the Phase 2 Drill Program as data updates will be transferred daily to the supervising geophysicist and geological team to include in the drill plan design.

Metallis' Chief Geologist, Dr. Razique, stated "A great deal has been observed and learned regarding the high-grade gold potential of the Cliff and Cole systems over the course of the Phase 1 field program. The completed work has given us new information of great significance to facilitate the collaring of drill placements, especially as we target the high-grade gold and deep copper-gold potassic zones that were identified through our previous two seasons of drilling and field work."
