Toronto, Ontario – June 28, 2022 (Newsfile Corp.) (Investorideas.com Newswire) Seabridge Gold (TSX: SEA) (NYSE: SA) introduced at the moment the outcomes of an up to date Preliminary Feasibility Research (the “2022 PFS”) for its 100% owned KSM challenge situated in northern British Columbia, Canada. The 2022 PFS exhibits a significantly extra sustainable and worthwhile mining operation than its 2016 predecessor, now consisting of an all open pit mine plan that features the Mitchell, East Mitchell and Sulphurets deposits solely. The first causes for the enhancements within the plan come up from the acquisition of the East Mitchell open pit useful resource and an enlargement to deliberate mill throughput. The numerous design enhancements over the 2016 PFS embody a smaller environmental footprint, decreased waste rock manufacturing, decreased inexperienced home fuel emissions by electrification of the mine haul fleet, a 50% enhance in mill throughput, and the elimination of capital-intensive block cave mining.
The 2022 PFS was ready by Tetra Tech, Inc. (“Tetra Tech”), the agency that had additionally authored the 2016 PFS. The 2022 PFS outcomes launched herein suggest mining solely 25% of the KSM useful resource stock and don’t embody materials from the copper-rich Kerr and Iron Cap deposits. An evaluation of a stand-alone improvement of those deposits will probably be included as a Preliminary Financial Evaluation (“PEA”) forming a separate a part of the NI 43-101 Technical Report back to be filed inside the subsequent 45 days.
Seabridge Gold Chairman and CEO Rudi Fronk famous: “We’ve got redesigned KSM for an inflationary atmosphere. The themes for this PFS are capital and vitality effectivity. The mine plan is simplified to carry whole capital down under 2016 estimates regardless of inflation by lowering sustaining capital. We’ve got completed this by eliminating underground mine improvement which is deferred to future years. Essential steps have additionally been taken to make the challenge much less depending on oil, particularly diesel gas, which is an inflationary scorching spot and prone to stay so. We’ve got performed this by maximizing using low value, inexperienced hydroelectric vitality.”
Notable enhancements within the Base Case 2022 PFS in comparison with the Base Case 2016 PFS embody:
- Confirmed and possible gold reserves enhance 22%, from 38.8 million ounces to 47.3 million ounces, attributable to greater gold grades added from the East Mitchell deposit.
- Mill throughput expands from 130,000 tonnes per day (“tpd”) to 195,000 tpd
- Waste to ore strip ratio decreased by 23% to roughly 1:1.
- A 90% enhance in common annual gold manufacturing, 22% enhance in annual copper manufacturing, 36% enhance in annual silver manufacturing, and a 363% enhance in annual molybdenum manufacturing.
- Whole capital of US$10.5 billion is decreased to $US9.6 billion with will increase from inflation and mill enlargement being wholly offset by the elimination of block cave mining from the PFS plan.
- Preliminary capital will increase from US$5.0 billion to US$6.4 billion primarily attributable to inflation.
- A 20 yr discount in mine life from 53 Years to 33 years as a result of elevated mill throughput equipped by greater open pit manufacturing.
- Whole after tax internet money move will increase from US$10.0 billion to US$23.9 billion.
- After tax NPV(5%) will increase from US$1.5 billion to US$7.9 billion.
- After tax IRR will increase from 8.0% to 16.1%.
- Payback interval drops from 6.8 years to three.7 years.
The 2022 PFS envisages an open pit mine operation that’s scheduled to function for 33 years. Ore supply to the mill is elevated from an preliminary 130,000 metric tpd to 195,000 tpd in Yr 3. Over your entire 33-year mine life, ore will probably be fed to a flotation and gold extraction mill. The flotation plant will produce a gold/copper/silver focus for transport by truck to a close-by seaport at Stewart, B.C. for cargo to Pacific Rim smelters. Metallurgical projections supported by intensive metallurgical testing challenge a copper focus with a median copper grade of 24% and a excessive gold (64 g/t) and silver (177g/t) content material, making it readily saleable. A separate molybdenum focus and gold-silver doré will probably be produced on the KSM processing facility.
Mineral Sources
The 2022 PFS makes use of beforehand disclosed useful resource estimates which are primarily based on US$1,300 per ounce gold, US$3.00 per pound copper, US$20.00 per ounce silver and US$9.70 per pound molybdenum. As well as, the assets are constrained by conceptual mining shapes.
Measured and Indicated Mineral Sources at KSM are estimated at 5.4 billion tonnes grading 0.51 grams per tonne gold, 0.16% copper, 2.4 grams per tonne silver, and 63 ppm molybdenum (88.3 million ounces of gold, 19.4 billion kilos of copper, 414 million ounces of silver, and 742 million kilos of molybdenum). An extra 5.7 billion tonnes are estimated within the Inferred Mineral Useful resource class grading 0.36 grams per tonne gold, 0.28% copper, 2.2 grams per tonne silver, and 33 ppm molybdenum (65.6 million ounces of gold, 35.1 billion kilos of copper and 406 million ounces of silver, and 415 million kilos of molybdenum). An in depth desk of KSM’s mineral assets could be discovered on the finish of this information launch
Mineral Reserves
Up to date Mineral Reserves for the challenge are primarily based on open pit mining of the Mitchell, East Mitchell and Sulphurets deposits. Waste to ore cut-offs have been decided utilizing a internet smelter return (“NSR”) for every block within the mannequin. NSR is calculated utilizing costs and course of recoveries for every metallic accounting for all off-site losses, transportation, smelting and refining fees. Steel costs of US$1,300 per ounce gold, US$3.00 per pound copper, US$20 per ounce silver and US$9.70 per pound molybdenum and a international alternate charge of 0.79 US greenback per Canadian greenback have been used within the NSR calculations.
Lerchs-Grossman (“LG”) pit shell optimizations have been used to outline open pit mine pit limits within the 2022 PFS. Open pit designed phases use up to date geotechnical design standards primarily based on latest website investigation packages. Mineral Reserves have been estimated utilizing the up to date pit designs. The open pit minimal NSR cut-off grade is different between Cdn$ 11/t to Cdn$25/t and considers the estimated course of working value of Cdn$10/t. Course of working prices embody plant processing (together with crushing/conveying prices the place relevant), G&A, floor service, tailings, and water therapy prices. A premium cut-off grade of Cdn$25/t is used till the tip of Yr 5 to maximise the NPV and decrease the time to payback of preliminary capital.
Manufacturing
The open pit solely mine manufacturing plan utilizing extremely class mining begins within the greater grade Mitchell pit. Manufacturing from the excessive grade higher East Mitchell zone is launched in Yr 3. Waste mined from the Sulphurets, East Mitchell and Mitchell pit is positioned within the Mitchell rock storage facility (RSF) till Mitchell pit is mined out by Yr 25. Ultimate waste from East Mitchell is backfilled into the mined out Mitchell pit from Yr 25 onward together with some waste rehandled from the Mitchell RSF.
The up to date mine plan reduces total footprint by not utilizing the McTagg RSF as required within the 2016 PFS and by using mined out pits for backfilling waste rock.
Autonomous mine operations the place relevant and an built-in distant operations centre scale back on-site personnel.
Electrification of the haul truck fleet with trolley help reduces carbon emissions and total mine vitality prices by changing diesel with low value vitality from electrical energy.
Mill feed ramps as much as 130,000 tonnes per day by Yr 2 adopted by a 50% enhance to 195,000 tonnes per day from Yr 3 onwards. Common annual mill feed throughput for the 33 years of mine life is estimated at 69.5 million tonnes.
At Mitchell, a near-surface greater grade gold zone crops out permitting for gold manufacturing within the first seven years that’s considerably above the mine life common. The mine plan is particularly designed for mining highest gold grade first to facilitate a fast capital funding payback. The challenge’s post-tax payback interval is roughly 3.7 years for the Base Case or 11% of mine life.
Capital Prices
Preliminary capital value (together with contingency of US$ 949 million) is estimated at US$6.4 billion, roughly 28% greater than the preliminary capital estimate within the 2016 PFS primarily attributable to inflation skilled over the previous two years. Preliminary capital assumes sure early works (e.g. roads and energy infrastructure) are being accomplished forward of a significant challenge development choice as part of the continuing KSM substantial begin actions.
Sustaining capital over the 33 yr mine life is estimated at US$3.2 billion, a discount of US$2.3 billion from the 2016 PFS, and is dominated by mill throughput enlargement and mine fleet ramp up in Yr 1 and a couple of, and tailings sustaining capital mid approach by means of the mine life.
Along with sustaining capital, an extra US$1,273 million has been charged towards the challenge together with US$653 million put aside in a sinking fund in the course of the manufacturing interval to pay for estimated water therapy obligations which proceed after closure and US$620 million for bodily reclamation and submit closure upkeep after mining operations have ceased.
Working Prices
Common mine, course of and G&A working prices over the challenge’s life (together with waste mining and on-site energy credit, excluding off-site delivery and smelting prices) are estimated at US$11.36 per tonne milled (earlier than base metallic credit). Estimated unit working prices decreased 8% from the 2016 PFS primarily as a result of change from mixed open pit and block cave mining to open pit solely mining, a 50% enhance in mill throughput capability, and know-how enhancements together with automation and electrification of the mine fleet.
Financial Evaluation
A Base Case financial analysis was undertaken incorporating historic three-year trailing averages for metallic costs as of June 20, 2022. This strategy is per the 2016 PFS Base Case. Two alternate instances are additionally introduced: (i) an Alternate Case that includes decrease metallic costs than used within the Base Case to reveal the challenge’s sensitivity to decrease costs; and (ii) a Latest Spot Case incorporating latest spot costs for gold, copper, silver and the US$/Cdn$ alternate charge.
The NI 43-101 Technical Report will embody sensitivity analyses illustrating the influence on challenge economics from optimistic and detrimental modifications to metallic costs, capital prices and working prices.
