PUSLINCH, ON / ACCESSWIRE / July 8, 2021 / Spruce Ridge Resources Ltd. (TSX-V:SHL) (the "Company") is pleased to announce that the Company has received the results of an updated Mineral Resource Estimate for the Great Burnt Copper and Gold Property in Central Newfoundland, that incorporates the results of the 2020 diamond drilling program on the Great Burnt Main Zone. The Mineral Resource Estimate was prepared by P&E Mining Consultants Inc. It will be used in a Preliminary Economic Assessment (PEA), expected to be complete later this year.
Table 1 shows the current (2021) Mineral Resource Estimate of the Great Burnt Property including the Main Zone and the South Pond "A" Copper-Gold Zone. Table 2 compares the 2021 and 2019 estimates for the Great Burnt Main Zone only (no new drilling was done on the South Pond Zones). The most prominent change is the increase in copper grades of the Main Zone, from 2.66% Cu to 3.21% Cu in the Indicated classification, with a smaller decrease from 2.41% Cu to 2.35% Cu in the Inferred classification. There was a matching increase in the contained copper content from 32.3 (Indicated) plus 30.4 (Inferred) million pounds (Mlbs) to 47.2 (Indicated) plus 25.0 (Inferred) Mlbs. The 2020 drill program comprised only infill drill holes; hence there was only a very minor increase in tonnage of the Great Burnt Main Zone; however, approximately one-fifth of the Inferred tonnage has moved to the Indicated classification.
CEO John Ryan stated "We are extremely pleased with the updated Mineral Resource Estimate at the Great Burnt Main Zone. Compared with the 2019 estimate, the Indicated Mineral Resource now has 46 percent more pounds of copper contained in just 21 percent more tonnes, with a 21 percent increase in grade. With the copper price having more than doubled over its 2020 low, and strong copper demand anticipated as electricity continues to replace fossil fuels, the Great Burnt Main Zone is looking as if it has a realistic prospect of becoming a commercially viable deposit, and we are eagerly awaiting the results of the PEA."

Mineral Resources which are not Mineral Reserves do not have demonstrated economic viability. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues, although Spruce Ridge is not aware of any such issues.
The Inferred Mineral Resource in this estimate has a lower level of confidence that that applied to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of the Inferred Mineral Resource could be upgraded to an Indicated Mineral Resource with continued exploration.
The Mineral Resources were estimated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), CIM Standards on Mineral Resources and Reserves, Definitions (2014) and Best Practices Guidelines (2019).
The 0.90% Cu cut-off grade was derived from the June 2021 Consensus Economics long term forecast Cu and Au prices of US$3.62/lb and US$1,650/oz, US$ exchange rate of $0.76, 95% process recovery, underground mining C$40/t, processing C$15/t, G& A $5/t and smelting/refining C$10/t.
CuEq% = Cu% + (Au g/t x 0.687)
Reasons for the Increase in Grade: The full results of the 22-hole, 3,114-metre drill program were published in News Release 2021-09 on March 18th, 2021. It was noted that the range of copper grades encountered in the 2020 drilling was significantly higher than the grades reported in historical holes drilled by Asarco in the 1960s. Similarly higher copper grades had also been noted in the smaller drill programs of 2016 and 2018. The provisional conclusion was presented, that the historical holes, which recovered EX core with a diameter of only 22 mm, using a standard (i.e. non-wireline) drill had lost a portion of the higher grade, massive sulphide intervals by grinding the core. This conclusion was supported by historical drill logs, which reported core recoveries in the mineralized zone that range from 13% to 100%, and averaged about 77%.
In other developments: Work is to commence in the coming week to make a 9-kilometre access trail from the Great Burnt Main Zone to the South Pond "A" Copper-Gold Zone and the South Pond "B" Gold Zone. Additional drilling is planned on the South Pond "B" Gold Zone, which does not yet have a Mineral Resource Estimate due to the wide spacing between historical drill holes. Drill results include 27.25 metres averaging 1.06 grams of gold per tonne (g/t Au) in hole GB87-08, 4.33 metres of 4.43 g/t Au in GB87-12 and 17.13 metres of 1.11 g/t Au in GB89-06.
