News Release – Vancouver, British Columbia – August 24, 2023: GSP Resource Corp. (TSX-V: GSPR) (the “Company” or “GSP”) announces the results of an updated 3D vein modeling of copper mineralization at the Alwin Mine Project (the “Alwin Property”), located in the Highland Valley Copper Camp of British Columbia.

The initial 3D copper mineralization model integrated over 4,000 individual copper assays from more than 450 historic diamond drill holes for which results are available combined with more recent 2008, 2020 – 2021 drilling (see the Company’s news release dated March 14, 2023). Based on these data, copper grade shells were generated via implicit modelling guided by structural trend surfaces based on the geometry of historically mined high-grade copper zones (see the Company’s news release dated April 17, 2023).

The updated interpretation incorporates recent diamond drilling, further refines the 3D geometry of the known historic zones and has resulted in the identification of additional mineralized zones not previously modelled (Figure 1).

Highlights of updated 3D copper mineralization vein model:

  • Updated 3D model constrained by downhole composited assays of copper mineralization vein intervals along structural trends based on the known 5 historic sub-vertical vein zones;
  • Potentially underground mineable high-grade copper focused 3D model utilizes minimum 1.5 m downhole assay composites and greater than 0.5% copper (Cu) cut-off to isolate high-grade copper zones demonstrating increased continuity;
  • Three (3) new copper mineralization vein zones identified that warrant follow up drill testing located to the south, northwest and at depth of known historic mineralization zones.

Historical diamond drill intercepts from three new copper zones include:

 South zone

    • Intersected in holes 68-45, 81-26
      • 68-45 (drilled from surface): 4% Cu over 2.0 m[1] from 45.1 m
      • 81-26 (drilled from underground):1% Cu over 4.3 m from 37.8 m
    • Possible eastern extension of South zone intersected by recent 2021 drilling[2]
      • AM-21-02 (surface): 2% Cu over 1.8 m from 52.5 m
    • Northwest zone
      • Intersected in holes 67-19, 75-17
        • 67-19 (surface): 8% Cu over 2.0 m from 67.1 m
        • 75-17 (underground): 3% Cu over 1.6 m from 31.6 m
      • Deep Zone
        • Two zones intersected historically in hole SS-73-8 (surface)
          • 3% Cu over 0.9 m from 325.8 m
          • 4% Cu over 2.1 m from 351.4 m


The updated 3D copper mineralization vein model will guide the prioritization of targets in the upcoming diamond drill program planned for Fall 2023. Historic drilling was primarily assayed for copper and had limited assay results for gold, and silver. Recent 2020 – 2021 drilling including 3.4% Cu, 40 grams-per-tonne (g/t) silver (Ag) over 6.4 m within dill hole AM-21-01A, and 10.4 g/t gold (Au), 1.2% Cu over 1.6 m within AM-21-08B highlights the polymetallic potential for zones to include gold and silver mineralization (see the Company’s news release dated April 17, 2023). The Company plans a diamond drilling program of approximately 1,200m to 1,500m to test 4 to 6 targets (200 to 300 m per drill hole), subject to available funds.

GSP’s President & CEO, Simon Dyakowski, commented: “The updated 3D copper mineralization vein model for the high-grade past producing Alwin Copper-Gold Mine once again points to the potential for expansion and discovery of additional copper and polymetallic zones. The broad extent of polymetallic mineralization at Alwin represents a significant exploration upside and requires confirmation drilling of known zones and testing of potential new zones identified to the northwest, south and at depth of the historic mine area. We look forward to prioritizing drill targets for our proposed upcoming diamond drill program in Fall 2023.”

About the Alwin Mine Project: The Alwin Mine Copper-Silver-Gold property is approximately 575.72 hectares and is located on the semi-arid, interior plateau in south-central British Columbia. The historic underground mine was developed over 500 m long by 200 m wide by 300 m deep. Production took place between 1916 to 1981 from five major subvertical high-grade copper mineralization zones totaling 233,100 tonnes that milled 3,786 tonnes of copper, 2,729 kilograms of silver and 46.2 kilograms of gold. The average diluted head grade was 1.5% copper.

The Alwin Property is adjacent with the western boundary of Teck Corporation’s Highland Valley Mine, the largest open-pit porphyry copper-molybdenum mine in western Canada.  Alteration and mineralization of the Highland Valley hydrothermal system extends westward from the Highland Valley mine onto the Alwin property (see GSP’s news release dated January 30, 2020).
