• Mineral resource model has been reviewed and confirmed by G Mining Services for use in the PEA study.
• The Company share price has outperformed the GDXJ by 155% since the updated MRE was published on February 6, 2024.
• Summer drill programs lead to identification of fault along the western edge of the Moss Gold Deposit that will allow the Company to focus its exploration efforts to expand the deposit to the west around the Moss Nose target.

Vancouver, British Columbia--(Newsfile Corp. - September 10, 2024) - Goldshore Resources Inc. (TSXV: GSHR) (OTCQB: GSHRF) (FSE: 8X00) ("Goldshore" or the "Company") is pleased to announce drill results from the summer drill program and provides an update on progress of its Preliminary Economic Assessment ("PEA").

• Scout Drilling Results Overview:
  • At the Boundary Zone a 6 - 8 meter (true width) shear zone was encountered with nuggety gold mineralization. A best intercept of 13.30m at 1.27g/t gold was encountered.
  • The Boundary zone is interpreted as a mineralized splay at 30 degrees to the Moss Gold Deposit trend and represents an exploration target as the Company looks to identify additional shear zones with similar orientations as potential drill targets adjacent to the 3.6km long Moss Gold Deposit.
  • Southwest Extension drilling has identified the location of a significant sinistral NNE-striking fault that is interpreted to offset the Moss Gold Deposit to the southwest. This provides a focus area to develop additional drill targets in the Moss Nose area that has to date been defined by selective rock grab samples and soil samples by the Company.
  • Intersected mineralization in the Southwest Extension was interpreted to be smaller scale peripheral shears to the main Moss trend.

• PEA Progress Overview:
  • G Mining Services Inc. ("G Mining") completed a Site visit on July 23, 2024 to evaluate potential infrastructure sites.
  • Mineral resource model has been reviewed and confirmed by G Mining Services for use in the PEA study.
  • Currently reviewing high level economics of several mining and milling scenarios to identify the optimal project for PEA study.

• Market Overview:
  • From publishing of the updated MRE on February 6, 2024 until August 31, 2024, the Company share price has outperformed the VanEck Junior Gold Miners ETF (the "GDXJ") by 155% with the Goldshore share price rising 191% during the period.
  • The Company has observed strong insider support with roughly 6 million shares acquired in the open market from May 1, 2024 until July 31, 2024, approximately 10% of the total volume during the period.
  • As of August 31, 2024, 6.4% of the Company stock is held by board and management with an additional 35.0% held by strategic shareholders which includes Brian Paes-Braga, Lutry Investments, members of the SAF group and close associates.

Michael Henrichsen, CEO of Goldshore commented, "The Company is pleased to provide an update as we continue to execute on our strategic plan. From a growth perspective we tested two important targets and gained valuable information to continue to explore in and around the Moss Gold Deposit. Of note to the technical team is the identification of a fault along the western edge of Moss that offsets the deposit to the south-southwest and will allow the Company to focus its exploration efforts to expand the deposit to the west along the Moss Nose target. In addition, solid progress has been made on the PEA study, the Company's largest catalyst in the next 6 - 7 months with G Mining Services. A site visit and a validation of the mineral resource model have been completed and the study is currently focusing on identifying the optimal mining and milling scenario for a phased production approach that will form the basis of the PEA study moving forward. We are encouraged by the strong performance of our share price, underpinned by the steadfast support of our strategic shareholders, who have consistently demonstrated their commitment through substantial open market purchases. This support has enabled us to continue transitioning shares into the hands of long-term shareholders, aligning our ownership structure with our long-term growth strategy."

Scout Drilling Results

The Boundary Zone program was designed to evaluate, and expand upon, historical drilling results to define the full extent of the high-grade shear zone. Drilling intersected broad zones of intense, strongly sericitized and sheared intermediate volcanics containing disseminated pyrite and pyrite-chalcopyrite stringers with narrow moderately sheared diorite dykes similar to what was recorded by Tamavack Resources Inc. in the historical core logs. The main mineralized shear is approximately 6 - 8 meters wide and strikes 030°, approximately 30 degrees away from the 060° regional foliation and dominant trend of shearing at Moss. Assay results confirmed the width of the mineralization reported in the historical drilling but failed to replicate the individual high-grade samples, suggesting a strong nugget effect in the zone, amplified by the historical drilling using BQ core which provides a smaller sample size.

Hole MBD-24-123, which intersected 13.30m at 1.27 g/t Au from 131.5m depth, was a near twin of the historical hole TML-87-04 which intersected 21.49m at 2.26 g/t Au (cut) from 148.5m. The latter was biased by a single 59 g/t gold sample, highlighting the impact of sample size on reported grades. The Company does not treat the historical estimates disclosed in this news release as current mineral resources.

Further regional exploration is being conducted along similar oblique structures to identify additional zones of mineralization. Significant results of the Boundary Zone scout drill program are summarized below in Table 1.

Drilling at the Southwest Extension targeted 300m and 600m step outs to the two mineralized zones associated with the Southwest Zone of the Moss Gold Deposit. Drilling intersected a foliated diorite intrusion complex containing the signature interchanging Moss alteration suite of sericite, silica, chlorite, hematite, albite, epidote, and carbonate. Minor (2-3%) sulphide mineralization, as is typical of the Moss deposit, was characterized by disseminated pyrite, with pyrite-chalcopyrite-molybdenite mineralization hosted in occasional quartz-carbonate veins.

Assay results showed wide intersections of anomalous gold mineralization containing sporadic multi-gram assays, but these assays do not cluster together to develop significant mineralized intercepts. A review of the trace element geochemistry noted an abrupt change in the chemistry of the host diorites at the Moss Gold Deposit suggesting a fault offset along the NNE trending Till Groove Fault shown to offset the nearby Moss stock by ~ 1km (Figure 1). A similar offset would align the extension of the Moss Gold Deposit with the Moss Nose prospect, which is being actively explored as part of the 2024 summer field program. Significant results of the Southwest Extension scout drillholes are outlined below in Table 2.

Mineral resources that are not mineral reserves have no demonstrated economic viability. There is no guarantee that any part of the mineral resources discussed herein will be converted to a mineral reserve in the future. The estimate of mineral resources may also be materially affected by geology, environment, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues.

PEA Update

G Mining continues to advance the PEA for the Moss Gold Project. G Mining has completed its review of the MRE, finding it acceptable for use in the PEA, while providing several recommendations on opportunities for further enhancement and improvement which are actively being incorporated into Goldshore's ongoing site programs. The G Mining team conducted a site visit on July 23, 2024 along with select Goldshore and CSL Environmental & Geotechnical Ltd. personnel, to evaluate opportunities for the placement of potential key site infrastructure. G Mining is currently reviewing a series of high level scenarios involving a variety of mining and milling options to identify the optimal project for PEA study. Importantly, Goldshore has elected to exclude the small gold resource at East Coldstream to focus on the larger part of the mineral resource at Moss and a smaller project footprint.
