Millrock Updates on 64North Gold Project Exploration, Goodpaster Mining District, Alaska

Millrock Resources Inc. (TSX-V: MRO, OTCQB: MLRKF) ("Millrock" or the “Company”) reports on advancements at the 64North gold exploration project, including an imminent drilling program. The project is the subject of an earn-in agreement whereby Resolution Minerals Limited (ASX: RML) (“Resolution”) is earning a joint venture interest from Millrock.

Drilling Program: The Resolution–Millrock technical team has developed a strong drill target area at the Tourmaline Ridge prospect, located on the West Pogo block. The target area was developed through analysis of all historic data, in addition to work that has been funded by Resolution over the past thirty months. Resolution plans to execute a drilling program of approximately 2,200 meters in five boreholes that will commence in late June 2022.

Earned Interest: Resolution has earned a 42% interest in the project by making cash payments (US$150,000), share payments (30,000,000 shares), and expending at least US$7.0 million on exploration (US$7.87 million spent as at January 31, 2022). Additionally, Resolution has elected to continue sole-funding exploration to earn a 51% interest by making further expenditures in 2022 and making further share and cash payments to Millrock.

Millrock President & CEO Gregory Beischer commented: “There is an abundance of geologic evidence pointing to a possible gold deposit at Tourmaline Ridge. We wish Resolution the best of luck as they move the project forward, and we are hopeful for a new gold discovery.”

A large soil geochemical anomaly measuring 1,800 by 750 meters occurs on the Tourmaline Ridge prospect. Recently Resolution reported that it had received rock sample assay results from trenches excavated at Tourmaline Ridge in fall of 2021. Numerous narrow, gold-bearing veins were detected. These steep-dipping veins are interpreted to be “antithetic veins”, which commonly occur in the hanging wall above gold ore bodies at the nearby Pogo mine. Prior historical drilling intersected these veins along with characteristic rock alteration and pathfinder minerals. From geophysical surveys, a moderately northwest dipping structure is interpreted to lie beneath the soil anomaly and historic drill holes. Resolution and Millrock interpret this structure to be the “Pogo Trend”, which appears to be traced from the Goodpaster deposit on the adjacent Pogo Mine property operated by Northern Star Mines Ltd. (“Northern Star”).

Northern Star recently announced a maiden inferred resource estimate of 1.1 million ounces of gold in 3.2 million tonnes of rock, averaging 10.3 grams per ton gold for the Goodpaster deposit.

As of March 31, Pogo is reported by Northern Star to host 6.59 million metric tonnes of proven and probable reserves, averaging 8.5 grams per metric tonne (1.8 million ounces) gold. (Northern Star ANNUAL MINERAL RESOURCE AND ORE RESERVE STATEMENT, May 5, 2022). More than 4 million ounces of gold has been mined at Pogo.

Note: Millrock has not independently verified the information reported by Northern Star. Also, Millrock cannot assure that the structures that host gold ore bodies at Pogo continue onto ground controlled by Millrock and that gold deposits of similar magnitude and concentration will be discovered.
