Goldshore Resources Inc. announced a mineral resource estimate for the Moss Lake deposit located at its 100%-owned Moss Lake Gold Project in Northwest Ontario, Canada. Technical Overview: Details of the MRE will be provided in a technical report with an effective date of November 14, 2022 prepared in accordance with National Instrument 43-101 ("NI 43-101"), which will be filed under the Company's SEDAR profile within 45 days of this news release. The MRE was prepared by independent mining consulting firm CSA Global Canada ("CSA Global"), a division of ERM Consultants Canada Ltd., in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") Definition Standards on Mineral Resources and Reserves (2014).

Moss Lake Geology and Model: The Moss Lake Gold Deposit is a structurally controlled gold deposit within the greenstone terrain of the Archean Superior Province. Mineralization is localized where the major NE-trending Wawiag Fault Zone cuts a dioritic to granodioritic intrusive complex. The deposit is defined by a series of anastomosing centimeter- to meter-scale NE-trending shear zones carrying higher- grade gold mineralization, and lower-grade gold mineralization associated with more brittle-style deformation and veining in the intrusive rock mass between the shear zones.

Mineralization is associated with pyritic sericitic and chloritic alteration and millimeter- to centimeter-scale irregular quartz-carbonate veinlets. Detailed geological logging and multi-element geochemical analysis of drill core from the 2021- 22 drilling has supported modelling of discrete shear domains within the larger altered and variably mineralized intrusive domain. The shear domains have a different higher-grade gold population to the low-grade intrusive domain and these domains have been estimated separately using different search parameters.

Importantly, this allows a more accurate representation of the true variability within the deposit than has been achieved in previous estimates. Drill Hole Data and QAQC Procedures: The Moss Lake Deposit has been evaluated by several diamond drill programs since the 1970s and earlier. The greatest number of drill holes were completed between 1986 and early 1992 by Tandem/Storimin and Noranda Inc. (311 drill holes for 86,196 meters).

A smaller drilling program in 2008 served to validate the older data and lead to the completion of the historical resource estimate ("historical estimate") by Moss Lake Gold Mines Ltd. in 2013. Following acquisition of the Moss Lake Gold Project, Goldshore commenced a drill program in 2021 that is still ongoing. The program aims to systematically redrill the deposit defined by previous campaigns and, in the process, to validate as much of the historical data as possible.

Prior to the 2008 program, there are no documented QAQC procedures or data available. Additionally, down-hole surveys were not undertaken or used an acid-bottle technique that measured dip and not azimuth. This is the case for most of the historical drilling which was completed in the late 1980s to early 1990s.

The ongoing Goldshore drilling program utilizes full industry-standard survey control and QAQC programs and is designed to systematically redrill the Moss Lake Deposit and validate as much of the historical drilling as possible through collar surveys, re-logging, and re-sampling. Mineral Resource Estimation Methodology: The current MRE is based on an improved understanding of the geological controls on gold mineralization that follows the detailed logging of 48 new drill holes (27,851.75 metres) drilled since August 2021 and with a drill hole database cut-off date of October 14, 2022. The MRE does not include the high-grade intercepts around the margins of the deposit reported on November 1, 2022.

CSA Global was provided with the wireframes for resource estimation by Goldshore. Goldshore modelled the shear zones domain using a combination of geological features and raw assay values above 1 g/t Au using explicit digitizing methods in Seequent Leapfrog 3D geological modelling software ("Leapfrog"). Goldshore modelled the intrusive domain using implicit modelling techniques in Leapfrog using a cut-off grade of 0.25 g/t Au.

CSA Global reviewed the provided wireframes to confirm validity for resource estimation. Statistical and geostatistical assessment of 1 m composites confirmed that the shear domains should be estimated within hard boundaries separating them from the intrusive domain. Statistical analysis was used to determine high-grade capping for each shear zone wireframe and ranged from 20 g/t Au to 60 g/t Au.

The MRE was estimated with a block size of 15 m x 15 m x 5 m utilizing subblocks and constrained within wireframes with a minimum width of 1.50 m. Gold content was estimated using ordinary kriging methods using dynamic anisotropy variogram models. The maximum range of the variogram models generally are between 60 m x 30 m x 10 m in the shear domain and 60 m x 60 m x 40 m in the intrusive domain. The search ellipse was constrained to selecting composites flagged within each domain and varied from half (1st), the full (2nd) and double the variogram ranges (3rd).

Additional check estimates were completed using inverse distance squared (ID2) and nearest neighbour methods, the latter on bench scale composites. Density values for 1,737 samples collected from all Goldshore drill holes were used to determine an average bulk density for each wireframed zone. Values range between 2.70 and 2.72 t/m3 for the mineralized domains, 2.7 t/m3 for waste rock, and 2.0 t/m3 for glacial overburden.
