Goldshore Intersects 5.64 g/t Au over 15.65m at East Coldstream

Significant Mineralization Outlined 13km Northeast of the Moss Lake Deposit

VANCOUVER, B.C., February 27, 2023: 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:

• R

esults from the second half of the East Coldstream Phase One drill program have

confirmed the potential for significant high-grade shears within East Coldstream,

appr

oximately 13 kilometers northeast of the Moss Lake Deposit. Best intercepts include:

o 3.

49 g/t Au over 26.35m from 76.85m depth in CED-22-010, including

 5.64 g/t over 15.65m from 87.55m

o 1.12 g/t Au over 21.9m from 206.5m

o 1.

07 g/t Au over 31.0m from 288.0m depth in CED-22-011 and

o 1.48 g/t Au over 18.45m from 357.0m, including

 4.68 g/t Au over 4.85m from 370.6m

o 0.

94 g/t Au over 25.05m from 218.95m depth in CED-22-014, including

 1.10 g/t Au over 16.0m from 226.0m

o 1.

23 g/t Au over 35.15m from 338.45m depth in CED-22-017, including

 2.19 g/t Au over 11.55m from 338.45m

n addition to the Moss Lake Deposit , the upcoming mineral resource estimate

update will include the East Coldstream deposit. In support of this, a 3D wireframe of

the mineralization constraining alteration domain has been developed utilizing both

current and historical drilling data.

P

resident and CEO Brett Richards stated: “These results at East Coldstream continue to support

our thesis that the size and scale of the entire Moss Lake Gold Project will be large enough to

support a material and meaningful update to the mineral resource estimate in April 2023, with

East Coldstream sequencing into the mine plan in a preliminary economic assessment as a

satellite pit. We look forward to the continuing catalysts to the Moss Lake Gold Project in an effort

to demonstrate the true value of the assets.”

Technical Overview

Figure 1 shows the location of East Coldstream relative to Moss Lake in addition to the now

formally identified gold and copper prospects controlled by Goldshore Resources. Figure 2 shows

the better intercepts in plan view, and Figure 3 is a typical section through holes CED-22-013 to

-015 and -017. Table 1 shows the significant intercepts. Table 2 shows the drill hole locations.

Results have been received for the eight remaining holes from the Phase One East Coldstream

drill program completed in the Summer of 2022.

All holes intersected visually distinct silica, carbonate, and hematite alteration zones hosted in

basalt flows – historically been referred to as the “Coldstream Basalt” – that host much of the gold

mineralization (Figure 4). This alteration also overprints and locally mineralizes quartz feldspar

porphyry sills and gabbro intrusions where they are intersected by shear zones. The altered

intrusions are significantly less “visual” than the Coldstream Basalt, which resulted in inconsistent

sampling of historical drill core. Infill sampling of intervals within the modelled alteration domain

represents an opportunity to expand mineralization. This is planned for the summer.

Goldshore has wireframed shear zone -hosted alteration domains (Figure 5 ) ahead of a m ineral

resource update planned for the second quarter. This consists of two major altered shear zones

– Main Lens and North Lens – and four minor altered shear zone splays. The Main Lens has been

historically split into the Main Lens and Sanders Lens however t hese two lenses are now

understood to be the same zone split by a late Proterozoic diabase dyke.

To evaluate the historical drilling, hole CED- 22-010 was drilled as a twin of hole C -10-23 in the

core of the East Coldstream deposit where both holes intersected two shear -controlled Lenses.

In the North Lens, CED -22-010 and C-10-23 intersected 1.81 g/t Au over 54.6m from 76.85m

versus 1.35 g/t Au over 54.2m from 80.4m, respectively. In the South Lens, CED -22-010

intersected 0.56 g/t Au over 51.5m from 206.5m versus 0.55 g/t Au over 34.7m from 196.6m,

respectively. This represents a 34% higher grade over similar widths in the North Lens and a 48%

increase in width with similar grades in the South Lens in the current drill hole.

The East Coldstream deposit also contains a broad, low -grade mineralized envelope within the

alteration domain. Examples include 0.54 g/t Au over 27.5.0m from 562.5m in CED-22-009; 0.56

4

g/t Au over 51.5m from 206.5m depth in CED-22-010; 0.33 g/t Au over 32.0m from 315m in CED-

22-012; 0.72 g/t Au over 18.1m from 182.05m in CED -22-013; 0.69 g/t Au over 25.05m from

254.95m in CED-22-014; and 0.85 g/t Au over 17.4m from 190.6m in CED-22-015.

Gold Project.

Pete Flindell, VP Exploration for Goldshore, said “These drill results show that East Coldstream,

which is well constrained by altered and mineralized shears, may be significantly larger than

previously understood. Our focus will now be on developing a mineral resource based around the

high-grade shears and their low-grade envelopes, which will form an important satellite to the

Moss Lake Gold Project approximately 13 kilometers to the southwest.”

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.

Director Resignation

Doug Ramshaw has announced he will step down from the Board of Directors of the Company at

the end of February 2023. Doug was instrumental in the formation of Goldshore and the

preliminary launch of the initial public offering in June 2021, and is stepping down to dedicate

greater time to Minera Alamos and other ventures he is involved in.

President and CEO Brett Richards stated: “Doug’s exceptional contribution to the Goldshore

Board has been a testament to the broad investor awareness created around the Company’s

launch and on-going development. I personally have thoroughly enjoyed working with Doug over

the last two years, as he has been sound counsel to myself and the Board, and on behalf of all of

us on the Board, we wish Doug the very best in his future endeavors.”
