Goldshore Resources Inc. (TSX-V: GSHR) (OTCQB: GSHRF) (FWB: 8X00), is pleased to announce its latest assay results from its ongoing 15,000 meter drill program at the Moss Gold Project in Northwest Ontario, Canada.  The primary goals of the winter drill program are to add to the current resource model by extending mineralization from depth into the top 100-200 meters from surface within the conceptual open pit and to demonstrate the potential for resource growth outside of the current mineral resource estimate.

Michael Henrichsen, CEO of Goldshore commented, “We are pleased with the latest batch of drill results which clearly demonstrate the potential for resource expansion at higher grades in the southwest area of the Moss deposit.  These results are exactly what we were anticipating to drive growth and demonstrate the true potential of the deposit moving forward.  We look forward to sharing additional results from the winter drill program and regional exploration program in the coming weeks and months.”

Technical Overview

Figure 1 shows the location of the drill holes being reported with respect to the planned winter drill program, while Figure 2 illustrates a cross section through drill hole MMD-24-139 that demonstrates significant mineralization above and below the current mineral resource. Tables 1 & 2 summarize significant intercepts and drill hole locations, respectively.

Figure 1: Illustrates the 2025 ongoing winter drill program targeting resource expansion within the conceptual open pit outlined in grey. Drill holes being reported are highlighted in red.

Figure 2: Drill section through MMD-24-139 illustrating a wider series of shears near surface that will allow the Company to model grade to surface. The section also highlights the growth potential beneath the open pit that may enable the open-pit resource to be as deep as the Main-QES pit

Drilling at the Southwest Zone aims to add to the mineral resource by infilling gaps within the current model created by sparse drilling. Drilling at shallow depths of 100-200 meters will allow for mineralized shear zones to be extended to the surface. Drilling at depths of 200 to 400 meters will allow the expansion of the open pit resource to a similar depth as the Main-QES pit (~500 meters).

Hole MMD-24-135 and MMD-24-138 were drilled along the western and eastern edges respectively of Snodgrass Lake to test the up-dip potential of lower grade shear zones concentrated close to the contact between the diorite intrusion complex and intermediate volcanic rocks that do not currently reach the surface in the current mineral resource estimate.   Hole MMD-24-139 was drilled from south of Snodgrass Lake to target the up-dip potential of marginal shears and the deeper extension of core shears below the conceptual open pit.

Hole MMD-24-135 collared into the edge of the high-grade mineralization and sheared altered granodiorite intrusion yielding grade intercepts such as 5.95m of 1.12 g/t Au from 6.5m depth. The hole quickly transitions into the wide multi-stage silica-sericite and epidote-chlorite altered diorite intrusion package, as is typical of the peripheral areas of the Southwest Zone, yielding broad lower grade intercepts such as 20.0m of 0.89 g/t Au from 81.0m, including 3.85m of 2.86 g/t Au from 87.0m, and 26.0m of 0.61 g/t Au from 107.0m, including 5.7m of 1.17 g/t Au from 107.0m.

Hole MMD-24-138 encountered a varying sequence of andesitic and dacitic volcanic rocks with a swarm of narrow sericite-silica-hematite to epidote-chlorite altered diorite dykes. Local shearing of the volcanics and diorites concentrates mineralization yielding intercepts such as 20.8m of 0.76 g/t Au from 108.8m, including 2.05m of 3.33 g/t Au from 123.3m. The hole was terminated, as the remaining volume had been previously drilled from the southwestern side of the lake.

Drill hole MMD-24-139 intersected 10 to 20 meter-spaced mineralized sericite-silica-hematite altered sheared granodiorite dykes close to surface before entering the main diorite intrusion complex at 245.2m, which was drilled for the remainder of the hole. The diorite complex consisted of interchanging epidote-chlorite and sericite-silica-hematite alteration with varying shear intensity including a mylonitized zone along the contact of a chloritized gabbro and a sericite-silica-hematite altered granodiorite with 2-3% pyrite±chalcopyrite±molybdenite (Figure 3). Results highlight the potential of expanding the high-grade mineralization beyond that defined within the conceptual open pit with the 20.55m of 2.58 g/t Au from 458.15m, including 14.7m of 3.52 g/t Au.  These intercepts occur 150 meters beneath the open pit constrained mineral resource. These results are top cut at 30 g/t Au, which only impacted a 1.0m veined shear assaying 36.1 g/t Au.

Analytical and QA/QC Procedures

All samples were sent to ALS Geochemistry in Thunder Bay for preparation and analysis was performed in the ALS Vancouver analytical facility. ALS is accredited by the Standards Council of Canada (SCC) for the Accreditation of Mineral Analysis Testing Laboratories and CAN-P-4E ISO/IEC 17025. Samples were analysed for gold via fire assay with an AA finish (“Au-AA23”) and 48 pathfinder elements via ICP-MS after four-acid digestion (“ME-MS61”). Samples that assayed over 10 ppm Au were re-run via fire assay with a gravimetric finish (“Au-GRA21”).

In addition to ALS quality assurance / quality control protocols, Goldshore has implemented a quality control program for all samples collected through the drilling program.  The quality control program was designed by a qualified and independent third party, with a focus on the quality of analytical results for gold. Analytical results are received, imported to our secure on-line database and evaluated to meet our established guidelines to ensure that all sample batches pass industry best practice for analytical quality control. Certified reference materials are considered acceptable if values returned are within three standard deviations of the certified value reported by the manufacture of the material. In addition to the certified reference material, certified blank material is included in the sample stream to monitor contamination during sample preparation. Blank material results are assessed based on the returned gold result being less than ten times the quoted lower detection limit of the analytical method. The results of the on-going analytical quality control program are evaluated and reported to Goldshore by Orix Geoscience Inc.
