Introduction & Operational Summary
During the September 2024 Quarter (the “Quarter”), Rimfire announced a 3Mt @ 240 ppm Sc (1,120t Sc Oxide) Indicated and Inferred Mineral Resource estimate at Melrose and a 21Mt @ 125 ppm Sc (4,050t Sc Oxide) Inferred Mineral Resource at Murga North, together with an Exploration Target for the surrounding Murga area (excluding Murga North) of 100 to 200Mt at 100 to 200ppm Sc (15Kt – 46Kt Scandium Oxide)*.
Declaring maiden Scandium Mineral Resources for Melrose and Murga North and an accompanying Exploration Target for the broader Murga area is an important first step in achieving Rimfire’s objective of building a globally significant scandium resource inventory at Fifield.
Murga North and Murga lie on the Fifield Project and Melrose lies on the Avondale Project. At the end of the Quarter, Rimfire issued a notice of termination to Rimfire’s exploration partner Golden Plains Resources (GPR) in respect of the Fifield Project Earn-in Agreement, with the termination stated to take immediate effect.
The Company exercised a termination right which has arisen as a result of a change of control of GPR following the judgement of the Victorian Supreme Court in: Resource Capital Ltd v Giovinazzo [2024] VSC 548 (Judgement), delivered 6 September 2024.
Separately on its 100% - owned projects, Rimfire drilled 5 diamond holes (974 metres) to test for extensions to previously drilled high-grade cobalt mineralisation at the Bald Hill Cobalt Copper prospect at Broken Hill. Assays received for the first drill hole confirmed further high-grade cobalt mineralisation and associated copper, i.e.; 18m @ 0.16% cobalt, 0.16% copper from 110 metres including 5m @ 0.21% cobalt, 0.23% copper.
Looking ahead to the December 2024 Quarter, our primary focus will be aircore drilling at the Murga Exploration Target to infill existing 400m x 400m spaced drill holes. Rimfire will also receive the remaining assay results from the Bald Hill drilling.

Figure 2: Evelyn Long Section (local grid) showing CuEq grade x thickness contours and current drilling pierce points. The view direction is to northwest.2
The drilling programme was successfully completed in late August 2024 with all holes intersecting visual sulphide mineralisation.13
The best observed intersection from the drilling programme was from 24AED002A, which encountered a strongly mineralised zone between 176.45m and 189.9m. Preliminary results from Minalyzer continuous XRF-scanning have confirmed the high-grade nature of the intersection (Table 1 and Figure 3).13
Table 1: Significant continuous XRF-scanning results for 24AED002A1
CAUTIONARY STATEMENT ON CONTINUOUS XRF SCANNING RESULTS:
Core was processed through the Minalyzer CS (Minalyzer) continuous XRF scanning unit in Perth. Six trays of calibration core samples were submitted with the new drilling, but no high-grade mineralisation was available. The results presented in this announcement are therefore considered partially calibrated as the upper limit of likely assays are not represented in the calibration core. The XRF results that are subject of this report will be submitted for laboratory assay and some variation from the results presented herein should be expected. For further information about the XRF scanning results and Minalyzer refer to the ASX Announcement dated 27 August 2024.

Key Projects
Doré Copper Mining’s assets are located within a well-known copper and gold mining region, with a long history of production. The company’s current strategy revolves around a hub-and-spoke model, with the Copper Rand mill serving as the processing hub, fed by multiple satellite deposits. The key projects in the PEA include Corner Bay, Devlin, and Joe Mann. Other past producing mines, like Cedar Bay and Copper Rand, have further exploration potential.
Corner Bay (Main Asset):
Corner Bay is the cornerstone of Doré Copper Mining’s portfolio. This copper-gold deposit has demonstrated exceptional grades and exploration potential, positioning it as one of the highest-grade copper projects in North America. The latest resource estimate, as of 2022, includes 2.7 million tonnes of indicated resources at a grade of 2.66 percent copper and 5.8 million tonnes of inferred resources at a grade of 3.44 percent copper. The deposit remains open in several directions and at depth, suggesting that further drilling could potentially expand the resource base and extend the mine life.
Corner Bay is expected to be mined by longhole open stoping with pillars and Avoca underground mining methods. The project will utilize existing infrastructure, including a portal and decline to a depth of 115 meters. The ore will be processed at the Copper Rand mill, with pre-concentration of the material through ore sorting technology at the Corner Bay site.
The PEA for the project anticipates a mine life of over 10 years, with the potential to produce 53 million pounds of copper equivalent annually. Metallurgical testing at Corner Bay has yielded positive results, with copper recoveries ranging from 96.8 percent to 98.2 percent, and the concentrate is of high commercial quality, making it highly attractive to smelters.
Devlin (Secondary Asset):
Devlin is a smaller satellite deposit located approximately 10 kilometers west of Corner Bay. The project has a measured and indicated resource of 775,000 tonnes at a grade of 2.17 percent copper, along with an inferred resource of 484,000 tonnes at a grade of 1.79 percent copper. While Devlin’s size is modest compared to Corner Bay, it plays a crucial role in Doré Copper Mining’s hub-and-spoke mining strategy. Ore from Devlin will be transported to Corner Bay for pre-concentration, before being trucked to the Copper Rand mill for final processing. The company is planning to employ room-and-pillar and drift-and-fill mining methods at Devlin, with operations expected to commence shortly after Corner Bay comes online.
Cedar Bay:
Cedar Bay is a past-producing mine located near the Copper Rand mill. It produced 3.9 million tonnes of ore at an average grade of 1.63 percent copper and 3.21 grams per tonne gold during its operating life. Doré Copper Mining drilling programs have defined in the southwest zone 130,000 tonnes of indicated resources at a grade of 9.44 grams per tonne gold and 1.55 percent copper, and 230,000 tonnes of inferred resources at a grade of 8.32 grams per tonne gold and 2,13 percent copper .
Joe Mann:
The Joe Mann gold-copper deposit is another component of Doré Copper Mining’s hub-and-spoke strategy. Located 60 km south of the Copper Rand mill, Joe Mann produced 1.2 million ounces of gold and 28 million pounds of copper over its mine life, at an average grade of 8.26 grams per tonne gold and 0.25 percent copper. The current resource estimate includes 608,000 tonnes of inferred resources, with an average grade of 6.78 grams per tonne gold and 0.24 percent copper. The PEA plan is to have Joe Mann operational once Devlin is depleted, and its ore will also be processed at the Copper Rand mill.
Copper Rand:
Copper Rand was historically the largest copper mine in the Chibougamau camp, producing over 16 million tonnes of ore during its operational life, which spanned from 1959 to 2008. The mine has excellent exploration potential, particularly at depth, where limited drilling was conducted before the mine’s closure. Copper Rand has historical reserves and resources, and excellent potential below previously mined areas.
