Goldsource Mines Inc. provided an update on its engineering and exploration activities for the Company's 100%-owned Eagle Mountain Gold Project ("Project") in Guyana, South America. The 2023 work program includes engineering activities focused on the delivery of a Preliminary Economic Assessment ("PEA") as well as generative exploration and drilling activities to test new targets within the Eagle Mountain Prospecting License ("PL") and expansion and infill drilling to facilitate engineering studies. Overall, the PEA and related engineering activities are progressing well with the announcement of results anticipated in the fourth quarter of 2023.

The PEA will be based on the April 2022 Mineral Resource Estimate ("MRE") comprised of an estimated 31.1 million tonnes ("Mt") grading 1.18 grams per tonne ("gpt") gold for 1,183,000 oz of gold in Indicated Resources, and 18.4 Mt grading 0.98 gpt gold for 582,000 oz of gold in Inferred Resources. The 2022 MRE is contained in a report titled "Eagle Mountain Gold Project, Potaro - Siparuni Region Guyana, NI 43-101 Technical Report" dated May 24, 2022, with an Effective Date of April 5, 2022. Engineering Activity.

Generative Exploration Highlights: Per plan in H1 2023, the Company expanded its generative exploration program focusing on adding to the pipeline of exploration targets within the PL and district properties outside the PL for which the Company has exploration agreements. In collaboration with independent geological consultants, the Company completed a multi-month review of all geological data with site visits to enhance exploration models for prospects. New concepts will be tested through the balance of 2023 with generative techniques and core drilling.

Soca Prospect and South Ann Prospect Drilling Highlights: Notwithstanding a reduction in drill metres prior to July 2023, several prospects were targeted within the PL. Results for thirteen (13) core holes totaling 1,652.5 metres for the Soca and South Ann prospects located approximately 1.5 and 1.1 kilometres, respectively, south of the 2022 MRE outline for the Eagle Mountain deposit along the Salbora-Powis north-south trend. Drilling has intersected mineralization along an aggregate strike length of approximately 275 metres, down to 170 metres depth, with high-grade gold intervals as well as broader areas of lower grade mineralization.

Recent drilling has extended the prospect by 100 metres to the east with the identification of two additional mineralized zones represented by four drill holes EMD23-281 to EMD23-284. Drilling at South Ann targeted an interpreted contact between a quartz-feldspar porphyry intrusion and granodiorite. Four drill holes (EME22-175 to EME22-177 and EME22-183) intersected gold mineralization, which has an aggregate strike length of 175 metres with several mineralized intervals.

Importantly, advancements confirm the current mineral resource model while also providing key information with respect to the geological genesis, which will enhance exploration targeting, notably in underexplored areas of the PL. EMEdefines core holes completed by contractor drill rig. True widths are estimated on mineralization orientation to drill core.

Saprolite and hard rock cut-off grades of 0.3 and 0.5 gpt gold, respectively. Soutex offers a wide range of services with its personnel having experience in plant operation, engineering, technical services, research and development, training, and process control, simulation and optimization. Such forward-looking statements concern Goldsource's strategic plans; timing and expectations for the Company's exploration and drilling programs at Eagle Mountain; mine development plans, preparation and timing of the PEA; and information regarding high grade areas projected from sampling results and drilling results.

Assumptions have been made regarding, among other things: conditions in general economic and financial markets; accuracy of assay results; reliability of the 2022 MRE; availability of mining equipment; availability of skilled labour; availability of skilled labour; timing and amount of capital expenditures; performance of capital expenditures; performance of available laboratory and other related services; availability of funds; availability of funds; and future operating costs; and future operating costs. The actual results could be available of funds; and future operating cost. The actual results could be made regarding, and future operating costs.
