Resource Estimates

Blue Star Gold Announces Ulu Gold Project

Update to Mineral Resource Estimate

Vancouver, British Columbia--(Newsfile Corp. - February 22, 2023) -

Blue Star Gold Corp.

(TSXV:

BAU) (OTCQB: BAUFF) (FSE: 5WP0)

("Blue Star" or the "Company")

announces the Company's

Mineral Resource Estimate ("MRE") for the legacy Ulu Project (the "Project") in the High Lake Belt, west

Kitikmeot Region, Nunavut, Canada. The MRE conceptualizes potential open pit and underground

approaches to the mineral resource.

Highlights

Measured and Indicated Resource of 2.535 million tonnes at an average grade of 7.02 grams per

tonne ("g/t") gold ("Au") for 572,000 ounces of gold;

Inferred Mineral Resource of 1.283 million tonnes at an average grade of 7.34 g/t Au for 303,000

ounces of gold;

The updated geological model - using explicit vs the implicit techniques utilized in the previous

estimation - has helped define all the reported zones;

Gold mineralisation remains open for further expansion in all contributing zones;

Previously reported metallurgical studies indicate all zones in the MRE can conceptually be co-

mingled with +90% gold recovery; and

The multitude of gold showings and zones that have seen only limited detailed assessment

provides the Company with excellent resource expansion potential throughout its district scale

projects.

Blue Star's CEO, Grant Ewing, commented

, "Blue Star's work to further its understanding of the

geological setting and mineralisation types has resulted in a substantial improvement in the continuity

within the resource models, and a much stronger overall MRE. The majority of the Flood Zone resource

lies in the higher confidence measured and indicated category. Additionally, there is potential for the

resource to have an open pit component with relatively high grades which was not previously

contemplated. Some shortcomings in the old model were reviewed and revised, further strengthening the

MRE."

Mr. Ewing added

, "The improved understanding of the district geology by Blue Star's technical

team continues to lead to high potential resource growth target areas, many of which lie in close

proximity to the Flood Zone deposit. Future drilling campaigns will systematically assess these high

potential zones, many of which have seen limited to no drilling historically."

Results of the Mineral Estimation are as follows:

The independent and qualified person for the Mineral Resource Estimate, as defined by NI 43-101,

is Chris MacInnis, P.Geo (#2059) from ALS-GoldSpot Ltd.

Mineral resources, which are not mineral reserves, do not have demonstrated economic viability.

There has been insufficient exploration to define inferred resources above as indicated or

measured mineral resources however, it is reasonably expected that the majority of the inferred

mineral resources could be upgraded to indicated mineral resources with continued exploration.

There is no guarantee that all or any part of a mineral resource can or will be converted into a

mineral reserve. The estimate of mineral resources may be materially affected by environmental,

permitting, legal, title, taxation, socio-political, marketing, or other relevant issues.

The mineral resources in this estimate were calculated using the Canadian Institute of Mining,

Metallurgy and Petroleum (CIM), CIM Standards on Mineral Resources and Reserves, Definitions

and Guidelines prepared by the CIM Standing Committee on Reserve Definitions and adopted by

CIM Council (CIM 2014 and 2019).

The MRE is underpinned by data from 544 on site diamond drill holes totalling 112,880m of

drilling.

The MRE is reported at a cut off of 1.5 g/t Au for the conceptual open pit and 3.5 g/t Au for the

conceptual underground extraction scenarios. The cut-off grades and potential mining scenarios

were calculated using the following parameters; mining cost: $110.00/t UG and $4.13/t OP; G&A

and site service costs: $44.20/t; processing cost: $36.3/t; recoveries 92%; gold price US$1750.00

per ounce; and minimum mining width of 2.0 metres in order to meet the requirement that the

mineral resources show "reasonable prospects for eventual economic extraction."

Original Au assays were composited to 1m with 4,231 composites generated in the mineralised

domains including 3,934 composites generated for the Flood Zone, 81 composites for the NFN

Zone and 154 composites for the Gnu (Nutaaq) Zone.

Grade interpolation was performed by ordinary kriging (OK) for the Flood Zone and inverse power

of distance to the third power for all other zones.

The informing data was composited to 1.0m for all

zones except GNU, which used a 0.75m composite size.

High grade capping supported by statistical analysis was completed on composite data from each

zone and was established at 41 g/t Au for the Flood Zone, 35 g/t for the Gnu(Nutaaq) Zone and 41

g/t Au for the NFN Zone.

All figures are rounded to reflect the relative accuracy of the estimates. Metal content is presented

in troy ounces (tonnes x grade (g/t) / 31.10348).

The Author is not aware of any known environmental, permitting, legal, title-related, taxation, socio-

political or marketing issues or any other relevant issue not reported in the technical report that

could materially affect the MRE.

The effective date of the MRE is 08 February 2023 and a technical report on the Ulu Gold Project

will be filed by the Company on SEDAR within 45 days of the date of this news release.

Full results tables and additional maps and geological sections will be made available on the

Company's website.

The Ulu Gold Project MRE is based on 544 diamond drill holes totalling 112,880 m spanning over thirty

years to the present along and adjacent to the Ulu Fold Hinge (Figure 1). The MRE represents a

significant adjustment in geological and mineralisation style understanding and confidence in the

mineralisation modeling to a historic MRE published by a previous operator in 2015 by:

Modeling distinct high-grade zones with lower grade zones where they occur, and modeling two

distinctive styles of mineralisation separately;

Addition of new assays from drilling campaigns in 2019 through 2022 totaling 88 drill holes for

15,391 m; and

Modeling portions of the mineral resources with a conceptual open pit mining scenario versus a

solely underground extraction scenario.

Blue Star Gold's Projects

The Company's properties are located approximately 525 km NNE of Yellowknife, NT in the Kitikmeot

region of western Nunavut. The hamlet of Kugluktuk is approximately 210 km to the NW. The Company

owns the Ulu Gold Property mining lease, an advanced gold project, the Hood River Property that is

contiguous to the Ulu lease, and the Roma Project. The three properties together encompass

approximately 26,700 hectares of the highly prospective and underexplored High Lake Greenstone Belt.

The Ulu mining lease hosts the advanced stage Flood Zone gold deposit, where a significant high-grade

gold resource has been outlined. Several additional gold prospects (including, but not limited to, Zebra,

Contact, Central, Axis, and Gnu) are spatially related to the axis of the ~5 km long Ulu Fold, which

extends from the Ulu lease onto the northern part of the Hood River property and culminates at the North

Fold Nose (NFN) Zone. The recent expansion of the Hood River concession added several new target

zones south of the Flood Zone gold deposit. The eastern side of the Hood River property is contiguous

to the Ulu lease, and hosts over twenty known gold showings. The Hood River prospects have the same

deformation history (including tight folding) as well as similar mineralization styles (acicular arsenopyrite

and polymetallic quartz veins) and stratigraphic sequences as the Flood Zone. One of the most

prospective target areas on the eastern Hood River property is the 4 km long Crown-Pro trend which has

seen only limited drilling.

The Roma project lies in the northern section of the High Lake Greenstone Belt. The project covers high

grade gold showings discovered by previous explorers, notably BHP Minerals from 1988 to 1994.

Multiple significant gold showings are present within a 6.5 km x 2.4 km area on the historic Roma claim

block. The original showing is a 0.30 to 3.0 m wide quartz vein exposed in outcrop and boulders for 2.0

km. In 1991, BHP drilled 10 shallow holes totalling 465 metres to test 1.72 km of strike of the vein. All drill

holes intersected quartz veins from 15 m to 37 m vertically below surface. Visible gold was noted in three

of the drillholes and the best results were 12.38 g/t Au over 2.31 m (including 64.0 g/t Au over 0.37 m)

from DDH MD-01, and 8.69 g/t Au over 1.87 m from MD-03. No drilling was conducted downdip of the

high-grade intersection in DDH MD-01 and no step out drilling to the north from this intercept was

conducted. No follow up drilling is known to have been completed on this property since BHP's initial drill

program in the 1990's. The Company has not verified the historical results from the Roma property and

has presented information obtained from two assessment reports submitted by BHP Minerals Canada

Ltd.; McMaster, G., (1995). Roma 3,4,5 and 6 Claims 1995 Geological and Geochemical Report, and

Anonby, L. and Jopson, W., (1992). Geological, Geochemical, Geophysical and Drilling Report on the

Roma 1 and 2 Claims.

The site of the future deep-water port at Gray's Bay is 40 - 100 km to the north of the properties, and the

proposed route corridor for the all-weather Gray's Bay Road passes in close proximity to the Roma, Ulu,

and Hood River projects.
