Grant Mine Option To Purchase Agreement

Millrock has entered an option to purchase agreement concerning the Grant Mine with owner Roger Burggraf. Consideration is US$2.0 million to be paid over a six-year period. The new property will form part of the larger Ester Dome exploration project, which is subject to an agreement between Millrock and partner Felix Gold. Felix has paid the costs to secure the Grant Mine claims and can, at any time in the next twelve months, elect to assume the option agreement rights. In the event that Felix Gold assumes the option rights and proceeds to make the purchase of the Grant Mine, Millrock will vest with a 1.5% Net Smelter Return royalty on gold production with an advanced minimum royalty provision. The Grant Mine is a former-producing gold mine reported to have produced approximately 25,000 ounces of gold. Production reports and estimates of unmined gold resources have been made by a third-party independent geologist in a Ni43-101 report (Bundtzen T.K., 2008, Ester Dome Mineral Resource Estimation and Eagle Creek Exploration Results, Fairbanks Mining District, Alaska, July 31st, 2008, 117 pages).

Table 17.1 of the aforementioned report is presented below and shows combined Indicated and Inferred resources of 340,800 ounces of gold.

Plans are being made to do an initial round of drilling in Summer 2021. The longitudinal section presented in Figure 3 illustrates the historic mine workings and drill intersections obtained in the 1990s by operators American Copper & Nickel ("ACNC") and Silverado Gold Mines.

No exploration work has been carried out since the 1990s. Millrock has not independently verified the drill intersections indicated on Figure 3.

Fairbanks District Exploration Team

Felix Gold and Millrock are building an outstanding exploration team that is mandated to aggressively explore the Fairbanks Mining District and make new gold deposit discoveries. Felix Gold has appointed David Larimer to Vice-President of Exploration. Mr. Larimer will lead a team of Millrock geologists and technical staff, as well as coordinate amongst local and global experts to maximize the chances of discovery success. Prior to joining Felix Gold, Mr. Larimer was Principal Geologist in charge of exploration for Teck's Red Dog zinc mine in northwestern Alaska, and Chief Geologist for the Pogo Mine during the time it was owned by Sumitomo Metal Mining. Mr. Larimer is a graduate of the University of Alaska Fairbanks and is very knowledgeable on gold deposit genesis and exploration in the Tintina Gold Province.

Millrock President & CEO Gregory Beischer commented: "We have known of Dave Larimer for many years and watched his career progress. Previously, Dave was very helpful in developing Millrock's understanding of gold mineralization in the Goodpaster Mining District, south of Fairbanks. We think that Dave Larimer will be able to build an outstanding team of exploration geologists composed of Millrock staff, local Fairbanks experts, Felix Gold personnel, and global experts. As major shareholders of Felix Gold, our company will be very supportive and help unravel the geological puzzle presented for gold mineralization in the Fairbanks District."

Fairbanks District Land Holdings and Agreement Structure

Felix Gold, the private Australian company with which Millrock has made a strategic alliance with, has decided to defer a go-public decision while waiting for the gold market to further strengthen. A further capital raise as a private company is planned by Felix Gold to fund 2021 summer exploration. The amendment assures that Millrock will receive the agreed 10% share of the private company Felix Gold in the event that it does not go public. Royalty provisions of the original agreement remain unchanged. The original agreement between Millrock and Felix Gold was documented in a January 12, 2020 Millrock press release.
