Millrock Reports on Exploration Results, Return of Property, Apex Gold Project, Southeast Alaska

Key Highlights:

• Surface geochemical program completed August 2021 identified new gold in soil anomaly extending over one kilometer northeast of old workings.
• Results up to 1.09 ounces per ton gold and 1.10 ounces per ton silver in soil samples.
• Anomaly located downslope and along strike from the Apex Mine.
  

VANCOUVER, British Columbia, March 09, 2022 -- Millrock Resources Inc. (TSX-V: MRO, OTCQB: MLRKF) ("Millrock" or the "Company") reports that positive assay results from a sampling and mapping program carried out in August 2021 have been received and compiled. The soil sampling results indicate that known mineralization at the former-producing Apex Mine likely extends 1,000 meters to the northeast.

Millrock President & CEO commented: "These are excellent results that show the gold-bearing quartz vein structure known from historic mining has significant strike continuity. Some of the soil sample numbers are of exceptional tenor."

The exploration work was completed during August 2021 and consisted of a soil geochemical survey (439 samples), rock sampling (39 samples), and geologic mapping. Soil samples were collected along a 20 meter by 40 meter spaced grid. The survey was designed to test the presence and extent of gold-bearing quartz veins along strike and down-valley from known gold mineralization at the historic Apex and El Nido Mines located within the Cann Creek drainage.

All assay results have been received from the exploration work. A broad gold in soil anomaly was identified by the geochemical survey in the lower cirque valley of Cann Creek. Assays of soil samples returned values ranging from below detection to a maximum of 33,900 parts per billion gold (1.09 ounces per ton) and 34,400 parts per billion silver (1.10 ounces per ton). One hundred and seven of the 439 samples collected returned highly anomalous values exceeding 80 parts per billion gold. The anomaly occurs at approximately 300 meters elevation below outcropping vein exposures that host the Apex Mine and extends over one kilometer down valley from the historic workings, along strike of the vein swarm. The anomaly is also underlain by the same rock units (diorite and amphibolite) that hosts the Apex vein.

On August 12, 2021, Millrock announced that it had entered into an agreement with Coeur Explorations, Inc., a wholly-owned subsidiary of Coeur Mining, Inc. ("Coeur"), concerning the Apex gold project in Southeast Alaska. Under the agreement, Coeur agreed to fund approximately $200,000 worth of exploration work. Coeur has met its obligations by funding the work, but has elected to terminate the option agreement. Millrock is free to further explore the project on its own or find another earn-in partner.

Millrock President & CEO Gregory Beischer commented: "We enjoyed working with the Coeur Explorations team and thank Coeur for advancing the project. The soil anomaly presents a compelling target for drilling and significantly expands the strike potential of the small, historic underground mine".

Quality Control - Quality Assurance
Millrock adheres to stringent Quality Assurance - Quality Control ("QA/QC") standards. In this case, the assay work was done under an agreement between Coeur and the assay laboratory. Samples are kept in a secure location at all times. Samples were assayed at the Bureau Veritas laboratory in Vancouver, Canada. Preparation and analysis methods are described in further detail here. The sample preparation method codes utilized for the program were SS80 for Soils and PRP70-250 for Rocks. Analytical methods used were FA430 (lead collection fire-assay fusion-AAS finish) and MA250 (4 acid digestion Ultratrace ICP-MS) for all samples. A 10% QA/QC sample insertion rate was used for all samples: 5% CRM (Certified Reference Materials) of known gold concentration and 5% blank material. The Qualified Person is of the opinion that the results reported in this press release are reliable.

Qualified Person
The scientific and technical information disclosed within this document has been prepared, reviewed, and approved by Gregory A. Beischer, President, CEO, and a director of Millrock Resources. Mr. Beischer is a qualified person as defined in NI 43-101.
