GSP Resource Geological Compilation and Modelling Reveals Historic High Grade Gold Assays at Alwin Mine Copper-Silver-Gold Project
GSP Resource Geological Compilation and Modelling Reveals
Historic High Grade Gold Assays at Alwin Mine Copper-Silver-Gold
Project
News Release - Vancouver, British Columbia August 19, 2024: GSP Resource Corp. (TSX-V:
GSPR / FSE: 0YD) (the “Company” or “GSP”) provides an update related to ongoing advancement
of the Alwin Mine Copper-Silver-Gold Project (the “Alwin Property”). Recently compiled historic
and modern diamond drilling has highlighted the presence of high- grade gold mineralization at the
Alwin Property, which is not yet well understood, in addition to the well-established laterally and
vertically extensive high grade copper zones. New modelling has for the first time enabled 3D
visualization of the Alwin Mine Project s hear vein system (see Figure 1. - 3D model below) ,
enhancing the Company’s ability to target expansion and discover y of new zones of high- grade
copper mineralization.
Drill Database Validation Highlights Significant Gold Values
Digital capture of historical surface and underground diamond drilling highlights the polymetallic
nature of Alwin Mine mineralization. While all prior drilling was assayed for copper, a small subset
of core samples were also assayed for gold, silver and molybdenum.
Significantly, 1968 diamond drilling at Alwin yielded multiple high-grade gold intercepts including
assays of 61 grams-per-tonne (g/t) gold (Au), and a total of five individual assays greater that
20 g/t Au within surface drill hole 68- 67 over a 29.5- metre downhole interval (Table 1) . These
assays yield composite grades of 3.05 metres averaging14.4 g/t Au, including 1.52 metres grading
26.1 g/t Au; and 2.77 metres grading 8.6 g/t Au1.

High-grade gold values with drill hole 68-67 are supported by the Company’s modern diamond drill
results including drill hole AM -21-08B that returned 1.6 m grading 10.4 g/t Au and 1.2% Cu, in
addition to, 6.4 m averaging 2.3 g/t Au, 3.4% Cu, and 40 g/t silver (Ag) within drill hole AM-21-
01A1.
The most recent drilling completed by GSP returned gold values over wide intervals, including drill
hole AM-23-01 that intersected 12.8 m averaging 0.57 g/t gold ( Au), 2.42% Cu, and 47 g/t Ag
(3.14% copper-equivalent, CuEq); including 5.7 m averaging 1.22 g/t Au, 5.21% Cu, and 103
g/t Ag (6.77 CuEq) (see GSP Resource Corp. news release dated February 20, 2024).
Viewed together the historic and current diamond drill results for the Alwin Mine indicate the
presence of potentially significant gold values correlated with the known copper lodes , as both
high-grade narrow veins and broade r lower grade zones encountered across multiple drill holes
throughout the deposit. Importantly the distribution and grade of gold values across the Alwin
Property is not well understood and presents significant exploration upside alongside the well-
established high-grade copper mineralization.
Structure and Mineralization Model Expected to Yield Expansion and New Discoveries
The recognition of Alwin Copper -Silver-Gold mineralization as being hosted within a well -
developed en-echelon shear vein system is expected to yield opportunities for expansion of existing
and the discovery of new zones of mineralization at depth and along strike where the property remains
open. The current interpretation indicates the presence of a subvertical E ast-West trending parent
shear zone, within which steeply south dipping tension veins have developed. The intersection of
these features, likely focused along dilation jogs, has produced steeply southeast plunging continuity
of mineralization . These plunging mineralized zones were the target of expansive underground
development over a 250 -metre vertical extent ; however, with relatively little historic production.
This enhanced understanding of the structural controls on mineralization represents a significant leap
in the Company’s ability to develop high- conviction drill targets with meaningful potential to drive
expansion and discover new zones of high-grade copper mineralization.
1 The estimated true width of mineralization is approximately 60-70% of the drilled width; for 2021 and 2023 drilling

Updated Geological Modelling Project Progress:
The APEX Geoscience Ltd. (“APEX”) resource modelling team continues to progress the geologic
model development for the Alwin Project. APEX has completed 3D georeferencing of historic mine
plans and sections, and drill database validation. This data has allowed for the development and
finalization of over 20 mineralized shear vein lodes, which will be used to constrain an exploration
block model currently under development. In parallel, historic mine development depletion models
have now been reconciled with the modeled mineralized zones to inform eventual conceptual open
pit and stope optimization.
Updated workflow continues to progress as follows:
• 3D georeferencing of historical geological plans and sections (COMPLETE)
• Digitization of mineralized polygons, fault traces and point structure (COMPLETE)
• Implicit 3D modelling of shear vein lodes, and fault planes (COMPLETE)
• Validation of 3D underground development and mined stope volumes (COMPLETE)
• Handoff of finalized drill database and mineralization models to APEX geostatistical and
resource estimation team for block modelling (COMPLETE)
• Conceptual pit shell and stope optimization (UNDERWAY)
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).
