Operations Update For Aurora Target Drilling And Geophysical Surveys

VANCOUVER, BC – Millrock Resources Inc. reported on an update on drilling and other exploration at its 64North Gold project. Exploration work is being funded and managed by Resolution Minerals in a collaborative arrangement with Millrock as the project operator. The 64North Gold Project is a very large tract of claims in Alaska’s emerging Goodpaster Gold District. Drilling has been ongoing since early June and continues at present. The drilling program is focused on the Aurora Target.

The target being drilled at Aurora is adjacent and immediately west of the Pogo Mine property, which is owned and operated by Northern Star Resources Ltd. Northern Star has previously reported a gold resource of 5.95 million ounces of gold in a series of veins grading 9.6 grams per tonne gold. More than four million ounces of gold has already been mined at Pogo, and Northern Star has recently announced a new gold discovery called the Goodpaster deposit a short distance away from the mutual claim boundary. Millrock cautions that mineralization on the nearby Northern Star property is not necessarily indicative of gold mineralization hosted on the Company’s property. Presently, hole 20AU004 is testing a CSAMT conductive zone on-trend and below the Half-Ounce Gulch prospect (“HOG”). High-grade gold grab samples have been reported from prior workers at this site, and two historic drill holes intersected high-angle veins beneath the prospect. The earlier workers did not have the benefit of the CSAMT data and those earlier holes (MR12-01 and MR12-02) were not drilled deep enough to intersect the shallow-dipping conductive zone that Millrock postulates to represent low-angle fault structures with quartz veining, sulfides, and gold mineralization. The hole is presently at 900 meters depth below surface.

The Aurora target is a two-kilometer by five-kilometer zone of low-magnetic rocks adjacent to a late diorite intrusion. The setting is very similar to that observed at the nearby Pogo Mine. Millrock postulates that the late diorite body intruded along a westerly extension of the Liese Creek fault, which is known to have played a key role in the genesis of the Pogo gold deposits. Highly anomalous gold-bismuth-arsenic in soil is documented. High-angle gold-bearing quartz veins have been intersected by prior drilling. However, the few holes drilled by earlier workers did not go deep enough to intersect the low-angle, regional shear zone that is known to host gold at Pogo and the Goodpaster Deposit. Millrock believes this structure exists at the Aurora target.

Numerous zones of mafic rocks, fault zones, and quartz veins intercepted in drill hole 20AU001 fit with the exploration model. The low-angle, regional shear preferentially ruptured the mafic lithological layers. The Aurora Target is located in this regional shear and the current drill hole program will test the shear for gold mineralization in a variety of places. The regional shear at Aurora was detected by CSAMT and ELF ground-based geophysical surveys in 2019. The ZTEM airborne survey that was completed on July 8 and 9, 2020, has been executed in the same area, along with detailed airborne magnetic surveys. If the airborne methods are able to detect the regional shear effectively, the method may be applied elsewhere on the project in a very cost-effective manner.

Millrock has developed a comprehensive COVID-19 safety plan with clear protocols that will help keep the operating team safe. The plan has been submitted to the relevant agencies and approved by the State of Alaska. So far, the exploration team has remained in good health.
