Regional Location Map

  • 575 Hectares adjacent to the Valley Pit (Highland Valley Mine), Logan Lake, British Columbia
  • Brownfield project (past-producer) located adjacent to large active open-pit mining operation (Teck Resources Highland Valley Copper)
  • Located in mining friendly region of Southwestern British Columbia
  • GSPR has obtained historical data from historical operators and is consolidating and reinterpreting this data to support a 2023 Drill program

Alwin Mine 3D Digital Model

  • Includes known underground workings, separated into drift and declines, raises, cement filled, rock filled and open stopes and the numerous unmined copper+/- silver+/- gold mineralized portions of the 425 m long by 275 m deep by 150 m wide zone
  • GSP’s goal is to generate a bulk tonnage open pittable, underground, and/or block cave resource at the Alwin Mine
  • Potentially viable goal due to increasing copper prices, and the fact that an open pit operation with a much lower cutoff than 1.5% copper of the former underground mine may be able to economically mine the lower grade and smaller high-grade portions ignored by prior underground mining operators

2020 Phase 1 Drill Program

2020 Phase 1 Drill Program Completed

  • Deep high-grade intersection of 1.29% CuEq over 14.1m under the partially mined # 6 zone in hole AM20-10E
  • Deep medium-grade bulk tonnage intersection of 0.313% copper equivalent over 61.7m under the partially mined #6 and #3 zones in hole AM20-10E
  • New low-grade intersections of 0.21% Cu over 13.3m in hole AM20-10D and at surface 0.195% CuEq over 36.6m and deeper 0.198% CuEq over 22.15m in hole AM20-09

Phase 1 Drilling Plan Map 2020

  • The Phase 1 program was designed to infill between the surface, in between and under both shallow and deep historic drill or mine intersections and to test for additional mineralization north and south of the known deposit
  • Significant geological knowledge was gained regarding copper and molybdenum mineral zonation, timing, and similarities and differences with relation to the Valley-Lornex hydrothermal system

2020 Deep Drilling Highlights

Hole AM20-10E was wedged from 10D at 133 metres and successfully intersected the #1 zone and part of the unmined portion of the #6 zone and lastly the #3 zone. The #6 zone intersection returned 0.81% CuEq over 22.6m from 287.9m including 5.98% CuEq, (4.6% Cu, 0.6 g/t Au and 80 g/t Ag) over 2.6m


AM20-09 from the surface intersected “Alwin” style mineralization grading 0.195% CuEq over 36.6m including 1.05m grading 3.39% CuEq and from 104.3m 0.198% CuEq over 22.15m including 0.86% CuEq over 4.55 m

2020 Shallow Drilling Highlights

At the 225 m long shallow unmined portion of the #4 zone at the east end of the Alwin Mine high grade copper was intersected in 6 of 8 short drill holes reported highlighted by hole AM20-02 which returned 3.00% CuEq over 3.95m starting at 19.6m

In total 9 of 11 holes intersected shallow bulk tonnage mineralization highlighted by hole AM20-02 with 47.35m grading 0.31% CuEq starting from 5.5m to the end of the hole 52.85m


  • Copper mineralization has been known in the area now covered by the Alwin property since late in the 19th century. Small-scale mining was conducted in the property area during the early 20th century. Recent exploration and mining was conducted during two periods: from 1967 to 1982 and from 2005 to 2008.
  • From 1967 to 1970: 6,940 m of surface diamond drilling in 81 holes was drilled along the main Alwin mineralized trend, and 5,860 m of underground drilling in 119 holes was completed in 1,400 m of development workings in the Alwin mine.
  • 1980, Dekalb Mining Corp. expanded the capacity of the mill to 700 tons (636.4 tonnes) per day and resumed mining of the main Alwin mineralized trend. Total production was 155,000 tonnes grading 1.54% copper. Mining was suspended in 1981 due to low copper prices. At the conclusion of mining, a trackless development decline had been extended to a depth of 270 m below surface (to an elevation of 1,400 m a.s.l.) and 3,935 m of drilling had been completed in 76 underground holes. Dekalb calculated a resource around the mine workings after mining terminated. A summary of this historical resource estimate calculation was reported to be a total of 390,000 tonnes of mineralization grading an average of 2.5% copper after factoring for 25% dilution. No cut-off grade was reported.
  • This historic resource was not calculated to current specifications and standards, and it is not compliant with National Instrument 43-101. It can not be deemed to be a current resource and it can not be relied upon. As noted further, the Company is not considering the estimate as current and further drilling is needed in order to upgrade the historical resource estimate.
