SRCGF - Spruce Ridge Receives Positive PEA at Great Burnt Copper-Gold Property
(TheNewswire)
TheNewswire - February 23, 2022 - Spruce Ridge Resources Ltd. (TSXV:SHL) (OTC:SRCGF) (“Spruce Ridge” or the“Company”) is pleased to announce that it has received the resultsof a Preliminary Economic Assessment (“PEA”) on the Company’swholly-owned Great Burnt Copper-Gold Project in Central Newfoundland. The PEA is incorporated in a Technical Report, with an updatedMineral Resource Estimate that has an Effective Date of January17 th , 2022, prepared by P&E Mining Consultants Inc. (the“Technical Report”).
John Ryan, CEO of Spruce Ridge, stated “We are veryencouraged to have received this PEA, which illustrates the robusteconomics of a copper-gold mine at Great Burnt. Although the MineralResource is just over a million tonnes, the high copper grade providesa strong revenue stream, and we look forward to proceeding towardspossible mine development and production in the near term. The PEAuses a copper price of US$4.00 per pound, and the spot price of copperhas been higher than that since last April. The sensitivity analysisin the PEA indicates a base-case IRR of 23.3%, and if the financialmodel were to use the current NYMEX spot price of US$4.55 a pound, theIRR would rise to 81.5%. With industrialized countries movingtowards near-total electrification of their economies in response toclimate change, we envisage an increasingly strong demand for copperto continue for the foreseeable future”.
The PEA is based on an underground mine, with 20-metredeep “starter pits” to provide rapid cash flow, on both the GreatBurnt Copper Deposit and the South Pond “A” Copper-Gold Zone. Following are some highlights of the PEA:
Mine Life |
4.0 years |
Production rate |
1,000 tonnes per day |
Mining methods |
“Starter” open pits and underground mining withramp access |
Average grades over life-of-mine (LOM) |
2.13% Cu, 0.08 g/t Au after estimated dilution andlosses (blended average of open pit & underground, Great Burnt& South Pond) |
Processing |

Access: The PEA assumes that a new all-weatherroad will be constructed to link with existing forestry roads atAtlantic Lake, 27 km from the Great Burnt Copper Deposit and 17.5 kmnortheast of the South Pond “A” Copper-Gold Zone. This wouldreduce road distance from Great Burnt to Grand Falls-Windsor, thecommercial hub of Central Newfoundland, from its current 250 km toless than 90 km.
Mining Methods: The PEA envisages initial mining to take place in open pits to a depthof 20 metres at the Great Burnt and South Pond “A” Zone, whichwill partially finance the underground development phase. Underground access will be by decline ramp, with trackless transportof mineralized material and waste rock. Mining will be bylongitudinal-retreat longhole stoping. The Great Burnt Lower Zone,which has a relatively low dip, will be mined by a combination ofcut-and-fill and drift-and-fill methods.
Metallurgical Testwork: The Technical Report presents the results ofpreliminary metallurgical testwork carried out by SGS Lakefield. Acomposite sample was made up of quartered drill core from the 2020drilling program on the Great Burnt Main Zone, with an average gradeof 2.82% Cu and 0.03 g/t Au, to approximate the run-of-mine grade. It responded well to preliminary flotation tests. A locked-cycletest run on material ground to 80% minus 55µmproduced a concentrate grading 25.1% Cu and 0.23 g/t Au, with copperrecovery of 98.5% and gold recovery of 58.6%. The PEA used a grind to 80% minus 50µm, a copper recovery of 96%, aconcentrate grade of 25% Cu and a gold recoveryof 55%.
Preliminary tests were run on sorting using X-Rayatomic density, with a view to upgrading the run-of-mine material toreduce shipping and processing costs. Copper recovery was 80%, andthe grade was increased to 5.35% Cu. It was considered that the losswas excessive, and the PEA was completed on the assumption thatrun-of-mine would be trucked to a toll process plant. Further tests,possibly using different sensing equipment, are being considered forthe future.
The Technical Report includes an updated MineralResource Estimate that incorporated the results of the 2020 diamonddrilling program on the Great Burnt Main Zone, which was summarized innews release 2021-12 on July 8 th , 2021. It isrepeated in Table 2 below.

John Ryan, CEO, added “We are awaiting assay resultsfrom last fall’s 3,000 metre drill program on the South Pond “B”Gold Zone, and anticipating that this may give us a possible additionto the Mineral Resource. Furthermore, we will be doing infill andstep-out drilling at the South Pond “A” Copper-Gold Zone, whichwill firm up - and possibly add to - that Mineral Resource. We willalso be following the recommendations of the Technical Report to doadditional drilling on the Great Burnt Copper Deposit, with a view toconverting some of the Inferred Mineral Resource into the Indicatedclassification.”
