Shear Domain at the Moss Deposit increases to 3.35Moz at 1.84 g/t Au within 56.5Mt

Vancouver, British Columbia–(Newsfile Corp. – May 8, 2023) – Goldshore Resources Inc. (TSXV: GSHR) (OTCQB: GSHRF) (FSE: 8X00) (“Goldshore” or the “Company“) is pleased to announce an updated mineral resource estimate (the “Moss MRE“) for the Moss deposit (“Moss” or the “Moss Deposit“) and a maiden mineral resource estimate (the “East Coldstream MRE” and, together with the Moss MRE, the “MRE“) for the East Coldstream deposit (“East Coldstream” or the “East Coldstream Deposit“), both located at its 100%-owned Moss Gold Project in Northwest Ontario, Canada (the “Moss Gold Project” or the “Project“).

• Moss Gold Project global inferred resource grows 44% to 6.00Moz at 1.02 g/t, within 183.6Mt.

• Moss MRE grows with 24% more contained gold ounces and 32% more tonnes from 4.17Moz Au in 121.7Mt (November 2022 mineral resource estimate) to 5.42Moz Au at 1.03 g/t Au within 163.6Mt (open pit and underground).
• The shear domain has increased in contained metal and tonnage from the November 2022 mineral resource estimate by 52% and 63%, respectively, to 3.35M oz Au at 1.84 g/t Au within 56.5Mt (open pit only).
• There is clear expansion potential over the 8km-long belt through strike extensions (in both directions) and parallel shears where gold mineralization has been intersected but is sparsely drilled.
• East Coldstream MRE introduced at 580Koz at 0.91 g/t Au in 20.0Mt (open pit and underground).
• Implied stripping ratios are 5.2:1 for Moss and 6.4:1 for East Coldstream.
• This resource increase implied by the Moss Gold Project demonstrates the scale of the project and the opportunity for a high-grade open-pit gold project.
• Work is well underway on studies to support a preliminary economic assessment (“PEA”) planned for later this year.
• The Moss Gold Project is host to 29 additional targets over a 35 km trend, which the Company continues to evaluate, and prioritize for future drill campaigns.
• The Company has incurred discovery costs of approximately CAD$10 per ounce of inferred Au resource (all-in) including acquisition costs and overheads. This can also be measured as approximately 76 ounces Au per meter drilled (all-in costs included) in the 78,000 meters drilled to date.

Please review “Notes to Accompany Moss MRE” and “Notes to Accompany East Coldstream MRE” for additional information.

President and CEO Brett Richards stated: “This announcement is an important milestone for Goldshore and the Moss Gold Project. We are pleased with the results of the MRE, as it illustrates the size, scale, and potential of the Moss Gold Project that we have been communicating for the past many months. This important step in the development of the Project will now shift to commencing a PEA by putting a mining project around the resource with the goal of understanding the economic outputs.

“Today’s MRE is a first step towards understanding a potential first phase of the Moss Gold Project, as we believe it represents only a small portion of the mineralization or potential mineralization on our land package. We still have 29 additional targets to drill test, including several gold targets, but also 4 interesting base metal and battery mineral targets.

“We will now start to run scenario planning for the PEA with respect to how we construct a Phase 1 project of a clearly larger mineral resource, while investigating various leaching methodologies, including heap leach. When we have a clear picture of the scope of the PEA, we will guide the market as to when we believe the results of it will be available to the market.”

Technical Overview

Details of the MRE will be provided in a technical report with an effective date of May 5, 2023, prepared in accordance with National Instrument 43-101 (“NI 43-101“) standards, 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).

Additional Exploration Potential

The modelled shear and intrusion domains extend to much greater depth below the optimized open pit constraining the reported Moss MRE. The shears are also open along strike, beyond the modelled strike length of 3.6 km. Historical drilling has intercepted gold mineralization over a total strike length of 8 km, which has been a focus of Goldshore’s summer soil geochemistry and structural mapping programs. Furthermore, there remains potential for additional parallel shears with gold mineralization in historical drill holes 500 m to the southeast of the Moss Deposit.

Moss Deposit Geology and Model

The Moss 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 intrusion 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 weaker shearing and a more brittle-style deformation and veining in the intrusion rock mass and adjacent wall rocks between the shear zones. Mineralization is associated with pyrite, sericite and chlorite alteration and millimeter- to centimeter-scale irregular quartz-carbonate veinlets.

Detailed geological logging and multi-element geochemical analysis of drill core from 120 new holes total 68,802m from the 2021-23 drilling has supported modelling of discrete shear domains within the larger altered and variably mineralized intrusion domain, which includes adjacent volcanic wall rocks. The shear domains have a different higher-grade gold population to the low-grade intrusion domain and these domains have been estimated separately using different search parameters. Importantly, this allows a more accurate representation of the true grade variability within the deposit than has been achieved in previous estimates.

CSA Global was provided with the wireframes for resource estimation by Goldshore. Goldshore modelled the shear zones domain using a combination of geological features, including core orientation data, and raw assay values above 1 g/t Au using explicit digitizing methods in Micromine 3D geological modelling software. CSA Global modelled the intrusion domain using implicit modelling techniques in Leapfrog using a cut-off grade of 0.20 g/t Au in 15-meter downhole composites. Statistical and geostatistical assessment of 1 m composites confirmed that the shear domains should be estimated within hard boundaries separating them from the intrusion domain. Statistical analysis was used to determine high-grade capping for each shear zone wireframe and ranged from 30 to 60 g/t Au.

The Moss MRE was estimated with a block size of 9 x 9 x 3 m utilizing subblocks and constrained within wireframes with a minimum width of 3 x 3 x 1 m. Gold content was estimated using ordinary kriging methods using dynamic anisotropy variogram models. Mineral resources are presented as undiluted and in situ. The historical underground voids from Noranda’s 1980’s exploration program have been removed from the geological model.

East Coldstream Deposit Geology and Model

The East Coldstream Deposit is a structurally controlled gold deposit located approximately 15 km northeast of the Moss Deposit within the Moss Gold Project area. The East Coldstream Deposit’s mineralized zones are located on the south margin of a shear zone which separates a gabbroic intrusion to the north from a mafic-intermediate volcanic suite to the south. Mineralization is found within sheared volcanic units, proximal to sills of quartz and quartz-feldspar porphyries and distinctive, brick-red syenites. The mineralized zones show silica, carbonate, and hematite alteration. Mineralization consists of fine disseminations of pyrite and lesser chalcopyrite throughout the silica-hematite zones as well as within quartz-carbonate veinlets. Iron carbonate is present in areas proximal to strong silicification. The two main mineralized zones have been cut by a north-south-trending diabase dike.

Sixteen new drill holes, totaling 7,973 m, were drilled in the East Coldstream Deposit to gather the required geological understanding of the deposit. Mineralization was modeled by CSA Global guided by alteration wireframes provided by Goldshore. Implicit modelling techniques were utilized in wireframing a NE-trending shear zones carrying higher-grade gold mineralization which is subdivided into two parallel domains (Z-2 and Z-4), and two satellite subparallel lenses (Z-1 and Z-3). A lower grade wireframe was developed surrounding the shear zone domains representing mineralization associated with more brittle-style veining in the felsic to intermediate metavolcanic rocks, gabbros, and porphyries between the main shear zones.

Exploratory data analysis was used to determine high-grade capping for composites of two of the shear zones, with top cuts ranging from 13 to 15 g/t Au. The East Coldstream MRE was estimated with a block size of 6 x 6 x 6 m utilizing sub-blocks and constrained within wireframes with a minimum width of 3 x 3 x 3 m. Gold content was estimated using ordinary kriging methods using dynamic anisotropy and informed by variogram models. Mineral Resources are presented as undiluted and in situ.

Drill Hole Data and QA/QC Procedures

The Moss 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 by Moss Gold Mines Ltd. in 2013.

The East Coldstream Deposit has been evaluated by several diamond drill programs since 1987. Most of the historic drilling was conducted between 2010 and 2011 by Foundation Resources who completed total of 66 diamond drillholes in the Coldstream deposit, totaling 16,988 m.

There are little documented QA/QC procedures or data available for programs prior to 2008.

The ongoing Goldshore drilling program utilizes full industry-standard survey control and QAQC programs and is designed to systematically redrill the deposits and validate as much of the historical drilling as possible through collar surveys, re-logging, and re-sampling.

Mineral Resource Classification

The Moss MRE has been classified as an inferred mineral resource. This resource classification reflects the fact that much of the drill hole data used for the resource estimate is historical, and no QA/QC data or reports exist for the majority of these drill holes. Statistical assessment of historical data and recent data provided some support for the historical data, but also included some inconsistencies. Goldshore’s planned program of infill and confirmatory drilling is expected to support classification of indicated mineral resource in subsequent mineral resource updates.

Reasonable Prospects for Eventual Economic Extraction

To support reasonable prospects for eventual economic extraction for the MRE, CSA Global used the estimated block model to generate an optimized open pit using Datamine NPV Scheduler software and the following assumptions: a gold price of US$1,650/oz, plant recovery of 92.5% and 96.5% for Moss Deposit and the East Coldstream Deposit, respectively; processing costs of US$12.50/tonne, mine-site general and administration costs of US$2.50/tonne processed, mining costs of US$2.70/tonne moved, and an overall pit slope angle of 50 degrees. NPV Scheduler Software is widely used by mining engineers to apply the Lerchs-Grossman algorithm to block models in order to generate optimized pit shells upon which economic open pit mine designs may be based.

The MRE is are constrained within the selected optimized pit shells which reach a maximum depth of approximately 450m and 250m in the Moss Deposit and East Coldstream Deposit, respectively.

Next Steps

In late 2022, Goldshore commenced an extensive program of relogging and resampling of all historical drill holes whose collars have been located and accurately surveyed. Where possible, these drill holes are also being surveyed using modern downhole surveying equipment. Resampling of historical drill core is ongoing, although most core blocks are now illegible rendering resampling impossible.

Pete Flindell, VP Exploration for Goldshore, said, “This MRE has highlighted the larger scale of gold mineralization on the Moss Gold Project. It remains conservative in many areas because of the concerns over historical drill data and we look forward to updating the quality and quantity of the mineral resource inventory following a comprehensive infill drill program. In the meantime, our field programs continue to develop our better exploration targets with the potential to add significantly to our resource base. At the same time, we will be working on the PEA, which will optimize and evaluate the many mining and milling options available to us. These include a high recovery flotation-regrind-leach mill process, potential heap leaching of low-grade mineralization and mining at different scales to maximize gold grades fed to the mill.“

Vancouver, British Columbia–(Newsfile Corp. – May 3, 2023) – Goldshore Resources Inc. (TSXV: GSHR) (OTCQB: GSHRF) (FSE: 8X00) (“Goldshore” or the “Company“), is pleased to announce the preliminary results from its PEA-level metallurgical test work at the Moss Gold Project in Northwest Ontario, Canada (the “Moss Gold Project“). The results were produced from the recent metallurgical testing program completed by Base Metallurgical Laboratories in Kamloops, British Columbia under the overall supervision of Ausenco Engineering Canada Inc. (“Ausenco”).

Highlights:

• Test work shows significantly increased gold recoveries from a flotation-regrind-leach process averaging:
  • 93% recovery at Moss
  • 98% recovery at East Coldstream
• These results represent an 8% to 13% increase in gold recoveries from previously conducted standard leach test work.
• Coarse bottle roll leach test results returned gold recoveries between 53% and 64%, which encourage investigation of a low recovery heap leach solution for low-grade mineralization that may bring gold production forward and reduce tailings.

President and CEO Brett Richards stated: “We are very pleased with the early results from the metallurgical test program, as recoveries have increased from the InnovExplo’s 2011 mineral resource estimate and subsequent 2013 preliminary economic assessment by 8%-13%. This detailed testing being undertaken will enhance the economics of our new mineral resource estimate due out in the near future; and the new preliminary economic assessment due to commence immediately thereafter. As well, these results also appear to provide early support for heap leaching the low-grade material, which positively changes the dynamics of an economic analysis.”

The metallurgical gold recovery test-work was conducted to assess the potential gold recoveries and potential process flowsheets for the Moss Gold Project, which include the Moss Gold Deposit (“Moss”) and East Coldstream Gold Deposit (“East Coldstream”). Testing started in early 2023 on composite and variability samples from the Main, QES and SW Zones at Moss, and from East Coldstream. The program included comminution testing, grind optimization for leaching and flotation, gravity concentration, and leach testing. Cyanide destruction and solid liquid separation testing are still ongoing and will be completed later in Q2 2023.

Gold Recovery Test Work Results Summary

The program evaluated 18 discrete composite samples representing the two gold deposits. Each composite consisted of multiple samples collected from diamond drill core and coarse rejects. Primary composites were selected for the Main / QES Zones (three samples), and one sample each for the SW Zone and East Coldstream deposits to reflect grade, spatial and lithological distributions. The composition of the primary pit composites was designed to have anticipated average grades that will be confirmed in a planned mineral resource estimate. Variability samples were selected to provide representation from higher grade shear zones and lower grade host rocks from the deposits.

Crushing and Grinding Testing

Comminution testing characterized sample hardness by Steve Morell Comminution (“SMC”) testing, Bond Rod Mill (“RWI”), Ball Mill Work Index (“BWI”) and Bond Abrasion Index (“Ai”) tests. Three samples from the Main QES deposit were used for this testing.

The results showed:

• SMC Axb average value of 34.7, indicates the samples are competent.
• Average RWI and BWI values of 18.4 and 19.5 (metric) respectively, considered hard to very hard range of hardness.
• Average Ai value of 0.175 g, which is classified as low to moderately abrasive.

Gravity Concentration Testing

The Main and QES Zone composite samples were tested with the Extended Gravity Recoverable Gold protocol to determine their amenability to gravity concentration.

The results showed:

• Moderate Gravity Recoverable Gold content totaling 40% gold.
• At full scale, this would be in the 10% to 15% gold recovery range.

Leach Testing

Coarse Particle Size Leach Tests

Intermittent bottle rolls leach tests were conducted on the samples at crush sizes of -6.25 mm and -2 mm to evaluate potential for heap leaching. Tests were run over 8 days with bottles rolled for 1 minute per hour.

The results showed:

• Average leach extraction for the -6.25 mm crush size samples is 52.6% Au.
• Average leach extraction for the -2 mm crush size samples is 64.2% Au.

Standard Leach Tests

Initial standard bottle rolls leach tests were completed on the primary composites from Main and QES Zones, over a range of grind sizes with 48 hours leaching and without gravity concentration prior to leaching. The results showed a weak relationship between grind size and recovery. As a result, a grind of 80% passing 100 microns was selected for further testing. The selected retention time was 48 hours. Gold leach extractions averaged 84% for these tests.

A total of 25 leach tests were conducted including initial screening tests and a bulk leach test (pending) that will generate sample for cyanide detox testing. The results showed:

• Gold leach extractions ranging from 74% to 93%, averaging 83%, with final residue values of 0.08 g/t to 0.32 g/t gold, averaging 0.20 g/t gold.
• Calculated gold head grades ranging from 0.40 g/t to 3.06 g/t gold, averaging 1.36 g/t gold.
• Shear Zone samples and low-grade Intrusion domain samples showed similar leach extractions to higher grade shear zone samples, based on leach residue grades as a function of head grades.
• Sodium cyanide consumption averaged 0.50 kg/t.

Flotation-Leach Tests

Testing was also completed using a flotation-leach flowsheet which includes:

• Grinding to 80% passing 100 microns.
• Flotation of a sulphide concentrate.
• Concentrate regrind to 80% passing 15 microns followed by 48 hours leaching.
• Flotation tailings leach without regrinding for 48 hours.

Results were positive with higher extractions than the standard leach tests. Key results include:

• Sulphide concentrate mass recoveries averaged 11%, ranging from 5% to 19%.
• Concentrate leach extractions averaged 96%, ranging from 92% to 98%.
• Flotation tailings leach extractions averaged 76%, ranging from 69% to 90%.
• Combined leach extractions averaged 93%, ranging from 87% to 98%.
• Calculated gold head grades ranging from 0.60 g/t to 2.77 g/t gold, averaging 1.46 g/t gold.
• Sodium cyanide consumption averaged 0.75 kg/t.

A summary of the results from the primary composites with the two flowsheets evaluated are shown in Table 1.

Table 1: Moss Project Primary Composite Leach Extractions Based on Flowsheet

Composite ID	Head Grade (Au g/t)	Recovery (Au%)
Whole  Ore Leach	Flotation Leach
Main/QES West Composite	1.48	84	89
Main/QES Central Composite	0.53	80	87
Main/QES East Composite	1.98	86	96
Main/QES Combined Composite	1.14	82	93
Southwest Zone Composite	0.83	76	93
East Coldstream Composite	2.64	93	98

Plant recoveries will be estimated with typical plant losses for use in the planned mineral resource estimate.

Pete Flindell, VP Exploration for Goldshore, said, “These metallurgical test results affirm our belief that gold recoveries in the sulphide-bearing shear zone mineralization can be significantly improved by flotation, while the low sulphide-bearing low-grade intrusion domain mineralization may be amenable to heap leaching. Further test work is required to investigate the latter, but we have now established +90% gold recoveries for the bulk of the contained ounces at Moss and East Coldstream are achievable with a flotation-regrind-leach circuit.”

Vancouver, British Columbia–(Newsfile Corp. – April 5, 2023) – Goldshore Resources Inc. (TSXV: GSHR) (OTCQB: GSHRF) (FSE: 8X00) (“Goldshore” or the “Company“), is pleased to announce that, further to its news release dated March 23, 2023 and due to strong investor demand, it is increasing the size of its previously announced brokered private placement offering (the “Offering“) to up to $6,000,000 aggregate gross proceeds of securities of the Company (the “Offered Securities“). The Offering is being conducted by Research Capital Corporation and Eventus Capital Corp., as co-lead agents and joint bookrunners (the “Lead Agents“), on their own behalf and on behalf of a syndicate of agents, including Laurentian Bank Securities Inc., Canaccord Genuity Corp., and Haywood Securities Inc. (together with the Lead Agents, the “Agents“). The Offering consists of the following Offered Securities:

• units of the Company (each, a “Unit“) at a price of $0.17 per Unit, comprised of one common share of the Company (each, a “Common Share“) and one-half common share purchase warrant (each whole warrant, a “Warrant“); and
• flow-through units of the Company (each, a “FT Unit“) at a price of $0.195 per FT Unit, comprised of one Common Share that will qualify as “flow-through shares” within the meaning of subsection 66(15) of the Income Tax Act (Canada) (the “Tax Act“) and one-half of one Warrant.

Each Warrant shall entitle the holder thereof to acquire one Common Share at an exercise price of $0.25, for a period of 24 months following the Closing Date (as defined below).

The Company has granted the Agents an option (the “Agents’ Option“), which allows the Agents to offer up to an additional 15% of the Offering, on the same terms as the Offered Securities. The Agents’ Option may be exercised in whole or in part at any time prior to the Closing Date of the Offering.

The Company intends to use the net proceeds raised from the sale of Units for working capital and future exploration work on its Moss Lake gold deposit in Northwest Ontario, Canada.

The gross proceeds from the issuance of the FT Units will be used for “Canadian Exploration Expenses” within the meaning of the Tax Act (the “Qualifying Expenditures“), which will be renounced with an effective date no later than December 31, 2023 to the purchasers of the FT Units in an aggregate amount not less than the gross proceeds raised from the issue of FT Units. If the Qualifying Expenditures are reduced by the Canada Revenue Agency, the Company will indemnify each subscriber of FT Units for any additional taxes payable by such subscriber as a result of the Company’s failure to renounce the Qualifying Expenditures.

The Offering is scheduled to close on or about the week of April 12, 2023 (the “Closing Date“), or on such date as agreed upon between the Company and the Lead Agents, and is subject to the receipt of all necessary regulatory and other approvals, including, but not limited to, the approval of the TSX Venture Exchange. The Offered Securities will be subject to a hold period of four months and one day from the Closing Date in accordance with applicable securities laws.

The Company has agreed to pay to the Agents a cash commission equal to 6% of the gross proceeds of the Offering, subject to a reduction for certain orders on a “president’s list”. In addition, the Company has agreed to issue to the Agents compensation warrants of the Company exercisable for a period of 24 months, to acquire in aggregate that number of common shares of the Company which is equal to 6% of the number of Offered Securities sold under the Offering, subject to a reduction for certain orders on a “president’s list”.

This news release does not constitute an offer to sell or a solicitation of an offer to buy any of the securities in the United States. The securities have not been and will not be registered under the United States Securities Act of 1933, as amended (the “U.S. Securities Act“) or any state securities laws and may not be offered or sold within the United States or to U.S. Persons unless registered under the U.S. Securities Act and applicable state securities laws or an exemption from such registration is available.

Securities for Debt Transaction

The Company also announces that it has entered into an agreement to settle certain outstanding accounts payable in the aggregate amount of $513,157.18 (the “Debt“) owing to a creditor (the “Creditor“) through the issuance of 3,018,572 units (the “Debt Settlement Units“) at a deemed price of $0.17 per Unit (the “Securities for Debt Transaction“). The Debt Settlement Units will have the same terms as the Units issued pursuant to the Offering.

No new control person or insider of the Company will be created pursuant to the Securities for Debt Transaction. This is an arm’s length transaction.

The Company is proposing to issue the Debt Settlement Units to preserve cash to fund future operations. The Company’s board of directors believes that the Securities for Debt Transaction is necessary to provide the Company with a clean balance sheet to attract new capital and provide adequate hard dollar working capital into the second half of 2023.

The issuance of securities pursuant to the Securities for Debt Transaction is subject to the approval of the TSX Venture Exchange. All securities issued will be subject to a four month hold period which will expire on the date that is four months and one day from the date of issue.

Neither the TSXV nor its Regulation Services Provider (as that term is defined in the policies of the TSXV) accepts responsibility for the adequacy or accuracy of this release.
