Blue Moon Acquires the Turner Copper-Gold VMS Deposit to Further Advance its Western U.S. Critical Mineral Hub and Spoke Model

Christian Kargl-Simard, CEO of Blue Moon states: "Through our screening of Western US critical metals projects, Turner clearly met our spoke requirements with potential scale, timeline and logistics to our Springer hub. There is a clear synergy with the Blue Moon Mine to unlock with nearby rail infrastructure. Turner has seen limited exploration, with the potential for a VMS camp, along with unquantified cobalt potential. We plan to aggressively explore and develop Turner with establishment of an exploration drive into the deposit including both surface and underground drilling to support metallurgical work as soon as possible."

The Company believes that material that is extracted from Turner and the Blue Moon Mine may allow for comingling, or at least, use a similar flotation mill to produce both copper and zinc concentrates with strong precious metals credits. Additional metallurgical and engineering-related studies are required to verify if comingling is possible before it can be integrated into any future engineering report. These studies will be initiated to develop a PEA that is expected to incorporate the Blue Moon Mine and Turner with a new 1,800 tpd mill at the Company's Springer complex in Nevada. It is expected that the extracted material from both projects will be transported primarily by rail (Figure 1), however, transportation studies are required to demonstrate viability. The Company is targeting to complete these studies by the end of 2027. In the meantime, Blue Moon will initiate permitting for exploration drilling and underground development at Turner, which is expected to take 12 to 18 months. It should be noted that the Company undertook a similar permitting methodology for the Blue Moon Mine in California. For Turner, it will be assumed that there is no processing of extracted material in Oregon.

Turner (Copper – Gold – Zinc – Silver – Cobalt)

Turner is a Cyprus-type, VMS deposit that is located approximately 40 miles southwest of Grants Pass, Oregon near the border with California. The deposit can be potentially exploited by underground mining methods, and the project is contained within three patented mining claims, which total approximately 60 acres. An additional 574 acres of contiguous private land is also part of this transaction, as well as 15 unpatented lode mining claims.

The sulphide mineralization that comprises the deposit is hosted within primitive, ophiolitic volcanic rocks associated with sea floor volcanism in an extensional tectonic setting. Turner deposit has three distinct zones of sulphide mineralization: UHZ, MUZ, and MLZ; which are semi-tabular, stacked bodies that strike 130 degrees (southeast) and dip 35 degrees to the northeast. The known strike length of the sulphide mineralization is approximately 1000 to 1500 ft (305 to 457 metres) with a down dip extent of about 800 to 1000 ft (244 to 305 metres). The geologic continuity of the sulphide mineralization at Turner is well established through core drilling and 3D modeling of geology and structure.

In the May 17, 2010, historical PEA completed to NI 43-101 standards titled "Turner Gold Resource and Preliminary Economic Assessment" (prepared by: J.M. Marek, P.E.; B.W. Buck, R.P.G; M.D. Strickler, P.E.; S. Annavarapu, P.E.; and J.J. Moore, P.E.), there is a mineral resource estimate of 2.447 million tons of Indicated category material grading 1.25% copper, 2.79 g/t gold, 2.65% zinc, 9.64 g/t silver, and 0.05% cobalt, and 2.084 million tons of Inferred category material grading 0.99%, 2.73 g/t gold, 2.78% zinc, 19.91 g/t silver and 0.04% cobalt. The Company intends to disclose the mineral resource estimate ("MRE"), both Indicated and Inferred categories, as a historical MRE for Turner within the meaning of National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101") adopted by the CIM Council on May 19, 2014. It should be noted that the non-Independent Qualified Person for the Company has not done sufficient work to verify and validate the historical MRE, meaning the Company is not treating the historical MRE as current.

Modeling for the historical MRE was developed based on exploration drilling that was completed by previous operators and it is supported by information provided from 84 drill holes, totaling 19,542 feet, completed between 1957 and 1989. The historical, 2010 NI 43-101 MRE on the project is outlined below in Table 1.

The Company believes verification of the historical mineral resource estimate is required but existing modeling provides a starting point from which to start developing the confidence in the historical mineral resource estimate. Regardless, the favorable volcanic strata hosting Turner are characterized by a precious metal enriched depositional environment that makes Turner different than many similar deposits in its peer group. As such, former operators have published some exceptional drilling results from Turner over the years, some of which are shown on a drill plan map and drill section in Figure 2 and presented in more detail in Table 2.

Table 1: Historical NI 43-101 Mineral Resource Estimate (2010)

The Company's non-Independent Qualified Person believes Turner will require, among other things: (i) additional exploration diamond drilling on the MRE and data collection including assays and lithogeochemistry; (ii) further detailed 3D modelling on mineralization controls of the deposit geological and structural settings to support future MRE updates; (iii) continued metallurgical studies for base and precious metal recovery factors, as well as ore sorting work programs; and (iv) studies to scope any future potential for underground extraction through determining optimal cut-off grades, appropriate mining methods, and necessary ground support plans. However, the non-Independent Qualified Person believes the historical MRE to be reliable and relevant to informing the advancement of future exploration targeting and infill definition drilling on Turner, since the deposit is open at depth and along strike. Insufficient work has been done to properly quantify the true exploration potential of geological host rocks around Turner.

In terms of metallurgical studies outlined in the historical 2010 PEA, it was shown that the sulphide mineralization was amenable to conventional flotation, yielding three products: 1) a copper concentrate, 2) a zinc concentrate, and 3) a gold concentrate. No metallurgical studies have been completed in respect to cobalt, albeit analyzed extensively in the drill hole database, meaning there is an opportunity for the Company requiring additional testwork.
