GSP Resource Advances Geological Modelling of Alwin Mine Copper-Silver-Gold Project in Preparation for 2024 Expansion Drilling

The APEX Geoscience Ltd. ("APEX") resource modelling team has made significant progress in the geologic model development for the Alwin Project. To date, APEX has georeferenced in 3D space a total of 70 historic underground level plans and cross sections, digitally captured this data comprising detailed underground mapping completed during mining operations between 1968 and 1979. The modelling program has yielded over 18,000 mineralized polygons, 1,200 fault traces, and 300 structural strike and dip measurements (see Figure 1).

Anticipated workflow is progressing rapidly 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 (IN PROGRESS)

• Validation of 3D underground development and mined stope volumes (IN PROGRESS)

• Handoff of finalized geological, mineralization, and mine depletion models to APEX geostatistical and resource estimation team (PLANNED)

• Exploration block modelling, conceptual pit shell and stope optimization (PLANNED)

The APEX team has now progressed to the domaining phase of the 3D modelling exercise, by assigning individual mineralized lode codes to the underground mapping strings and mineralized drill intercepts leading to the development of a series of structurally informed implicit modelled wireframes. Refinement of the implicit model is currently underway, in parallel with analogous development of associated fault planes, and the development of a mined stope and development depletion model.

GSP reports that historic digital data capture and geological modelling completed to date has for the first-time enabled 3D visualization of a well-developed en-echelon shear vein system host to high-grade copper Alwin Mine. The current interpretation indicates the presence of a subvertical East-West trending parent shear zone, within which steeply south dipping tension veins have developed. The intersection of these features has produced steeply southeast plunging continuity of mineralization.

The APEX team is continuing to refine its interpretation of the geologic and structural model for the Alwin Mine, however the information currently available points to the prevalence of predictable shear-hosted vein geometries, which are expected to be readily targetable using structural geological principles. This information 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.

This work will build on the recent drilling campaign executed by GSP in late 2023 which returned significant high-grade mineralization including drillhole AM23-01 intersected 2.42% copper (Cu), 47 g/t silver (Ag), and 0.57 g/t gold (Au) over 12.8 m (3.14% copper-equivalent, CuEq); including 5.7 m averaging 5.21% Cu, 103 g/t Ag and 1.22 g/t Au (6.77% CuEq) (see GSP Resource Corp. news release dated February 20, 2024).

Simon Dyakowski, President & CEO of GSP, commented:

"With the Copper price recently achieving all-time highs above US$5/pound, GSP is rapidly advancing geologic and structural modelling of decades of historic exploration data related to a compelling and underexplored brownfield high-grade Copper project. This important work underway prepares the project for resource modelling and expansion drilling to build on GSP's recent drilling in the shallow high-grade copper-silver gold system."

About the Alwin Mine Project

The Alwin Mie 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).
