Metallis Engages Geotech to Fly Extensive ZTEM Survey over Kirkham

VANCOUVER, April 7, 2021 - Metallis Resources Inc. (TSXV: MTS) (OTCQB: MTLFF) (FSE: 0CVM) (the "Company" or "Metallis") is pleased to announce the Company has engaged the services of Geotech Ltd. to fly an extensive property wide Z-Axis Tipper Electromagnetic survey ("ZTEM" or "the Survey") over the Company's 100%-owned, 106 sq. km Kirkham Property (the "Property"). The Property is situated in the prolific Eskay camp of the Golden Triangle in northwestern British Columbia, a fertile region known for its past producing Eskay creek and Snip gold mines, Seabridge's KSM porphyry deposits and Pretium's producing Brucejack gold mine, amongst others.

ZTEM technology is exclusive to Geotech and is used to measure the variations in naturally occurring electromagnetic ("EM") fields produced by thunderstorms around the globe. These variations in the EM fields help detect the resistivity contrast in rock structures and zones of sulphide mineralization in multiple intrusions and its hydrothermal alteration and silicification. ZTEM can measure these contrasts up to 2 km deep, which is ideal for the exploration of the structurally controlled 4 km-long copper-gold Cliff Porphyry System which forms part of the larger 7.5 km-long Hawilson Monzonite Complex (or "HM") in the central area of the Property (Click here to View Map).

Metallis' Chief Geologist - Dr. Abdul Razique, PhD. P. Geo - commented, "Our key objective for the 2021 season is to identify and drill those deeper porphyry core zones along the Cliff Porphyry System. Based on the space-time distribution and sub-vertical morphology of the Cliff porphyry intrusions, the ZTEM is expected to provide vectors towards the deeper potassic core zones and distribution of copper-gold mineralization". He added, "These surveys have shown to be an effective tool in mineral exploration and have produced positive results at projects such as Olympic Dam in Australia, Pebble in Alaska, and most importantly, a ZTEM outlined Seabridge Gold's Deep Kerr deposit, part of its KSM Project, one of the world's largest undeveloped gold projects."

Collaboration with Eskay Mining Corp. and Garibaldi Resources Inc:

The ZTEM flight lines extend beyond the Kirkham property borders in order to gather background data from claims owned by immediate neighbors Eskay Mining Corp. ("Eskay") and Garibaldi Resources Inc. ("Garibaldi").

The eastern boundary area of the Survey will cover the newly identified western Anticline of the Eskay Rift which crosses both Metallis and Eskay claim groups. Metallis has agreed to cover the costs of the Survey in this area, and, in exchange, Eskay will fly their upcoming SkyTEM survey over part of the Kirkham Property. The combination of both ZTEM and SkyTEM surveys over the eastern border area will enable both companies to locate deep conductors associated with Eskay Creek type Volcanogenic Massive Sulphide ("VMS") deposits in the Hazelton Group of rocks and deeper sedimentary exhalites in the lower Stuhini group of rocks. Over 10 km of the Triassic-Jurassic unconformity (or the "Red-Line") has been mapped on Metallis' Property along with extensive outcrops of lower Hazelton stratigraphy. The ZTEM data will also be particularly useful in targeting the rhyolite-mudstone contact and potential VMS mineralization at the Company's Mount Dunn, Rhyolite Ridge and Terwilligen Creek prospects.

Along the northern property border, the interpreted data and logistical costs of the ZTEM survey will be shared with Garibaldi. This will help in targeting any deep-seated chambers and/or small open systems of E&L type gabbroic rocks along the northeast-oriented Nickel Mountain complex that extends onto Metallis' K-9 target at the southern flanks of Nickel Mountain.

Metallis' President and CEO Fiore Aliperti stated, "The Property has been surveyed by shallow penetrating VTEM surveys in the past, but the ZTEM has the potential to identify copper/nickel or giant porphyry copper deposits up to 2 kilometers below the surface. Signing a contract for a property wide ZTEM is a key step in advancing the Kirkham Project and, specifically, the 7.5 km-long Hawilson Monzonite Corridor." He went on to add, "Metallis has shown, yet again, we are here to work with our neighbors for the benefit of our project and, most importantly, our investors. The combination of geophysical surveys and exchange of information with our peers is a vital step towards an economic discovery at Kirkham."

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 northeast corner of Kirkham is within 12 km of the Eskay Creek mine while the eastern border is within 15 - 20 km of Seabridge Gold's KSM deposits and Pretium Resources' Brucejack mine.
