Toronto, Ontario – March 22, 2021 – Doré Copper Mining Corp. (the “Corporation” or “Doré Copper“) (TSXV: DCMC; OTCQB: DRCMF; FRA: DCM) is pleased to announce that it has entered into option agreements (the “Option Agreements”) to acquire a 100% interest in the former producing Norbeau gold mine property and the contiguous Beaurox property, a major land position totaling approximately 1,400 hectares (the “Properties”), located 15 kilometers by road north from the Corporation’s Copper Rand mill in the Chibougamau mining camp in northwestern Québec, Canada (Figure 1). All dollar amounts are stated in Canadian Dollars.

Highlights

• Cash payments totaling $465,000 over three years ($135,000 over the first year)
• Issuance of common shares in the Corporation (“Shares”) totaling $675,000 equivalent over three years
• Cash payments totaling $175,000 and issuance of a further $950,000 equivalent in Shares upon meeting certain technical milestones
• Spending commitments of $800,000 over 30 months
• Norbeau mine historical gold production of approximately 160,000 ounces (380,000 tonnes at 13.77 g/t) from 1965 to 1969; Lac Minerals sunk a 780-foot (238 meters) shaft eventually deepened to 1,580 feet (482 metres)
• On the Beaurox property to the east, trenching and limited shallow drilling identified additional veins (not mined) with intercepts of 4.1 g/t Au over 6 meters and 4.8 g/t Au over 2.8 meters at the Sharpe Vein and 10.8 g/t Au over 2 meters and 2.4 g/t over 14 meters at the New Vein (composite values)
• Limited or no drilling below 150-200 meters on both the Sharpe Vein and New Vein
• 2019 trenching at the New Vein encountered visible gold (Figure 2)
• No drilling or exploration on the Properties since the late 1980’s 

Ernest Mast, President and CEO, commented, “The Properties provide an opportunity to further consolidate our position in the Chibougamau mining camp with high-grade copper and gold assets and build on our strategy to create a near-term, profitable hub-and-spoke operation with our centralized 2,700 tpd mill. The high-grade gold historically mined at Norbeau with limited and no modern exploration since the 1980s provides a unique low-cost exploration opportunity, particularly to the east of the Norbeau mine with the Sharpe and New Veins.” 

Next Steps

The Corporation will be completing a detailed compilation of all available data on the Properties and initially plans to investigate both the New Vein and Sharpe Vein. Doré Copper is also planning an airborne geophysical survey for the second quarter of 2021.

About the Properties

The Beaurox property is comprised of 28 unpatented mining claims covering approximately 1,000 hectares and the Norbeau property is comprised 11 claims totaling 386 hectares. 

Norbeau Mine (see Note 1)

The Norbeau mine historically produced approximately 160,000 ounces of gold from 1965 to 1969 at a grade of 13.77 g/t Au. Approximately 80% of the production was from the Main Vein (Vein #1) and 20% from Vein #4. The shaft extends to 1,580 feet (482 metres) with 10 levels but little or no development on the last two levels. In 1980-81, the Norbeau mine was dewatered to a depth of 1,580 feet and 13 underground holes totaling 762.2 meters were completed to test Vein #9, a low-grade east-west structure in the footwall of the lower level stopes. In 1987, Westminer Mines Ltd. completed six surface drill holes totaling 3,426 meters to intersect the extension of Vein #4 below the 10^th level of the mine. Vein #4 was not intersected but new gold-bearing veins were found in the upper levels and below the 10^th level. The best intercept of the program returned 9.09 g/t over 2.6 meters (0.265 oz/t over 8.6 ft) in Vein #9 from 1,265.8 to 1,274.4 feet. No other work is reported after this period at the Norbeau mine.

New Vein (see Note 2)

The New Vein (also referred to as the Shecapio Vein), located approximately 500 meters east of the Norbeau shaft, was discovered in 1980 and outcrops over a length of approximately 250 meters with an average width of 3 meters. During 1980-81, the New Vein was channel sampled and 42 short surface drill holes totaling 2,900 meters were completed along an east-west strike length of 300 meters. Significant intercepts included 10.8 g/t Au over 2 meters (N-81-35), 2.4 g/t Au over 14 meters (N-81-11), and 11.2 g/t Au over 2 metres, including 95.3 g/t Au over 0.2 meters (N-81-22). The New Vein has not been drill tested at depths below 100-150 meters. 

Sharpe Vein (see Note 3)

The east-west Sharpe Vein, located a further 500 meters to the east, was channel sampled over the 203.8 meters length of the vein exposure by Beaurox Mines Limited in 1982. The grade was established at 6.86 g/t (0.20 oz/t) Au over an average width of 2.9 meters (undiluted and all samples cut to 1.00 oz/t Au), including 124.8 meters grading 8.23 g/t (0.24 oz/t) Au over an average width of 3.29 meters. In 1985, a systematic re-sampling of the Sharpe Vein was carried out with 87 channel samples and 21 holes totaling 1,128 meters over a strike length of approximately 350 meters (including 18 short holes totaling 873.9 meters on 50 feet sections testing 50 feet below surface). Significant intercepts included 4.1 g/t Au over 6 meters (SH-9-85)and 4.8 g/t Au over 2.8 meters (N-98). In 1987, two holes totaling 354.8 meters were drilled to test the Sharpe Vein to a depth of 100 meters with no significant gold intercepts. The Sharpe Vein has not been drill tested at depths below 100-150 meters. 

Vein #5 (see Note 4)

Other veins include Vein #5, which is located at the west end of the Sharpe Vein and strikes northwest. In 1985, seven holes were drilled over a strike length of 140 meters. The best value was 5.0 g/t (0.146 oz/t) Au over 1 meter (hole 5-4-85). Vein #5 was channel sampled fairly systematically over a strike length of 45 meters in 2015. The sampling returned an average of 6.84 g/t Au over a length 45.4 meters with average widths of 1.61 meters.
