VANCOUVER, B.C., November 2, 2022: Goldshore Resources Inc. (TSXV: GSHR / OTCQB: GSHRF / FWB: 8X00) (“Goldshore” or the “Company”), is pleased to announce assay results from its ongoing 100,000-meter drill program at the Moss Lake Project in Northwest Ontario, Canada (the “Moss Lake Gold Project”).

Highlights:

• Results for eight holes, drilled to both expand and infill historic but poorly surveyed drill sections in the Main Zone, have confirmed higher-grade gold mineralization within a large volume of well mineralized diorite with best intercepts of:
• 2.66 g/t Au over 8.15m from 18.1m depth in MMD-22-057 and
  • 1.34 g/t Au over 90.95m from 254.05m including
    • 2.42 g/t Au over 12m from 260.4m and
    • 4.02 g/t Au over 16.4m from 283.55m
• 1.02 g/t Au over 59.9m from 502m depth in MMD-22-056 including
  • 4.78 g/t Au over 9.35m from 542m
• 4.38 g/t Au over 9.5m from 84.5m depth in MMD-22-036
• 1.05 g/t Au over 26.45m from 373.55m depth in MMD-22-048
• 1.8 g/t Au over 18m from 121.0m depth in MMD-22-053 and
  • 1.3 g/t Au over 43.65m from 355.6m

Results for four holes, drilled to evaluate the under-drilled Southwest Zone, have confirmed narrow higher-grade gold mineralized structures with best intercepts of:

• 23.7 g/t Au over 3.5m from 182m depth in MMD-22-064
• 2.26 g/t Au over 8.25m from 388m depth in MMD-22-042

President and CEO Brett Richards stated: “Throughout our entire drilling campaign from 2021 to now, we have consistently and repeatedly delivered promising drill results, indicating not only the size and scale potential of the Moss Lake Project, but also the quality of the higher-grade areas of the deposit. As we illustrated at the end of H1 2022, our focus turned from identifying and drilling the size of the global resource; to identifying the high(er) grade sections contained within the historical resource (and stepped out from the historical resource), and focusing on building a much smaller open pit project PEA around this. The results from this change in focus are evident in press releases in H1 2022 and Q3 2022, and continue with the results highlighted today. To that end, we are expediting our independent mineral resource estimate (“MRE”) on the high(er) grade sections within the historical resource, and look to have the results of this MRE presented to the market by the end of 2022, versus the end of Q1 2023, as previously guided. This will also lead to the Company accelerating a preliminary economic assessment (“PEA”) on a smaller, high(er) grade resource, but much more manageable project in terms of CapEx and project timeline, versus a large-scale project PEA on an updated larger resource similar to the historic resource.  The target delivery to the market of the economic results of the PEA is slated for the end of Q1 2023, under current market conditions and circumstances, versus the end of Q2 2023, as previously guided”.

Technical Overview

Figure 1 shows the better intercepts in plain view and Figure 2 is a typical section through hole MMD-22-057.

Over the last month, results have been received for eighteen holes, including:

• Eight holes that have infilled areas of the Main Zone that are between sections drilled by historic holes with collar survey problems. They will replace the low-confidence historic holes in the upcoming resource model update.
• Four holes drilled to evaluate the under-drilled Southwest Zone.
• Five holes testing the margins of the main +1 g/t Au zones that provide valuable geological information in these marginal areas.

As with the historic holes, the Main and Southwest Zone holes intersected several broad zones of low-grade mineralization within the altered diorite intrusion host. Examples include 0.98 g/t Au over 50.9m from 51m and 0.32 g/t Au over 122m from 473m depth in MMD-22-036; 0.48 g/t Au over 88m from 388m and 0.53 g/t Au over 33m from 279m depth in MMD-22-042; 0.46 g/t Au over 133m from 443m depth and 0.35 g/t Au over 29.25m from 316.85m depth in MMD-22-048; 0.70 g/t Au over 126m from 335m depth and 0.89 g/t Au over 60.6m from 120.4m depth in MMD-22-053; 0.80 g/t Au over 25.35m from 563.65m depth in MMD-22-055; 0.64 g/t Au over 44m from 168m depth and 0.63 g/t Au over 33.65m from 237.35m depth in MMD-22-064; 0.47 g/t Au over 38.1m from 615.45m depth in MMD-22-066; and 0.46 g/t Au over 27.65m from 366.25m depth in MMD-22-078.

All these low-grade zones occur as envelopes to higher-grade structures that form a three-dimensional, anastomosing shear network that has developed in response to strain on the altered diorite intrusion. Results include the broad zones of +1 g/t Au mineralization shown in the highlights (e.g., 1.34 g/t Au over 90.95m from 254.05m depth in MMD-22-057) and several narrow high-grade intervals, including better intercepts of 39.3 g/t Au over 0.7m from 90.45m depth in MMD-22-036; 47.4 g/t Au over 0.5m from 420.25m depth in MMD-22-052; 11.4 g/t Au over 2.35m from 549m depth in MMD-22-056; 26.7 g/t Au over 1m from 287m depth in MMD-22-057; and 231 g/t Au over 0.35m from 182.75m depth in MMD-22-064.

Four holes were drilled into the Link zone and potential overlap between the QES zone and Moss Main zone to properly define the boundaries of each zone and to better understand the behavior of the southern edge of the altered diorite package. These dominantly drilled through the lesser altered and deformed porphyritic diorite phase containing several narrow lenses of low-grade mineralization as indicated by the historic drill results.

Geological modelling of the altered diorite host rock and anastomosing shear network at Moss Lake has progressed faster than anticipated and is now complete. As a result, the Company has embarked on an independent resource modelling exercise and has engaged international consulting group, CSA Global (an ERM group company) to complete this work. This will lead to a new Mineral Resource estimate that will be reported following National Instrument 43-101 standards for disclosure. This new estimate will be published before the end of 2022.

Pete Flindell, VP Exploration for Goldshore, said “These drill results continue the vein of local high grade gold mineralization that bulks out to produce 50- to 200-meter-wide zones of +1 g/t Au gold mineralization within a “sea” of low-grade mineralization. This style of mineralization is capable of producing large, low-grade gold resources with a significant volume of higher-grade mineralization. We anticipate that this should, with the selection of the appropriate gold price for the constraining Whittle shell, allow the reporting of a smaller, higher-grade resource at the Moss Lake Project.”

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 analyzed 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 (“QA/QC”) 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.

About Goldshore

Goldshore is an emerging junior gold development company, and owns the Moss Lake Gold Project located in Ontario. Wesdome is currently a large shareholder of Goldshore with an approximate 27% equity position in the Company. Well-financed and supported by an industry-leading management group, board of directors and advisory board, Goldshore is positioned to advance the Moss Lake Gold Project through the next stages of exploration and development.

About the Moss Lake Gold Project

The Moss Lake Gold Project is located approximately 100 km west of the city of Thunder Bay, Ontario. It is accessed via Highway 11 which passes within 1 km of the property boundary to the north. The Moss Lake Gold Project covers 14,292 hectares and consists of 282 unpatented and patented mining claims. 

The Moss Lake Gold Project hosts a number of gold and base metal rich deposits including the Moss Lake Deposit, the East Coldstream Deposit (Table 3), the historically producing North Coldstream Mine (Table 4), and the Hamlin Zone, all of which occur over a mineralized trend exceeding 20 km in length. A historical preliminary economic assessment (the “Moss Lake Historical Estimate”) was completed on the Moss Lake Gold Project in 2013 and published by Moss Lake Gold Mines Ltd. (“Moss Lake Gold Mines”)¹ ³. A historical mineral resource estimate (the “East Coldstream Historical Estimate”) was completed on the East Coldstream Deposit in 2011 by Foundation Resources Inc.² ³ In addition to these zones, the Moss Lake Gold Project also hosts a number of under-explored mineral occurrences which are reported to exist both at surface and in historically drilled holes. The Moss Lake Deposit is a shear-hosted disseminated-style gold deposit which outcrops at surface. It has been drilled over a 2.5 km length and to depths of 300 m with 376 holes completed between 1983 and 2017. The last drilling program conducted in 2016 and 2017 by Wesdome Gold Mines Ltd. (“Wesdome”), which consisted of widely spaced holes along the strike extension of the deposit was successful in expanding the mineralized footprint and hydrothermal system 1.6 km to the northeast. Additionally, the deposit remains largely open to depth. In 2017, Wesdome completed an induced polarization survey which traced the potential extensions of pyrite mineralization associated with the Moss Lake Deposit over a total strike length of 8 km and spanning the entire extent of the survey grids. 

The East Coldstream Deposit is a shear-hosted disseminated-style gold deposit which locally outcrops at surface. It has been drilled over a 1.3 km length and to depths of 200 m with 138 holes completed between 1988 and 2017. The deposit remains largely open at depth and may have the potential for expansion along strike. Historic drill hole highlights from the East Coldstream Deposit include 4.86 g/t Au over 27.3 m in C-10-15.

The historically producing North Coldstream Mine is reported to have produced significant amounts of copper, gold and silver⁴ from mineralization with potential iron-oxide-copper-gold deposit style affinity. The exploration potential immediately surrounding the historic mining area is not currently well understood and historic data compilation is required.

The Hamlin Zone is a significant occurrence of copper and gold mineralization, and also of potential iron-oxide-copper-gold deposit style affinity. Between 2008 and 2011, Glencore tested Hamlin with 24 drill holes which successfully outlined a broad and intermittently mineralized zone over a strike length of 900 m. Historic drill hole highlights from the Hamlin Zone include 0.9 g/t Au and 0.35% Cu over 150.7 m in HAM-11-75.

The Moss Lake, East Coldstream and North Coldstream deposits sit on a mineral trend marked by a regionally significant deformation zone locally referred to as the Wawiag Fault Zone in the area of the Moss Lake Deposit. This deformation zone occurs over a length of approximately 20 km on the Moss Lake Gold Project and there is an area spanning approximately 7 km between the Moss Lake and East Coldstream deposits that is significantly underexplored.
