Canstar's High-Grade Antimony Showings,

Including 74% Sb, at Golden Baie Highlight

Potential Critical Minerals Upside as Price

Rises on China's Export Restrictions

Toronto, Ontario--(Newsfile Corp. - September 5, 2024) -

CANSTAR RESOURCES INC. (TSXV:

ROX) (OTC Pink: CSRNF)

Canstar's Golden Baie Project is located 89 km southwest of the past-

producing Chinese-owned Beaver Brook Antimony ("Sb") Mine, which hosted a

2.2-million-tonne

deposit grading 3.99% Sb at 1.5% cutoff (Sandeman et. al., 2018)

. In addition to Golden Baie's

extensive gold anomalies—including over 315 bedrock samples with more than 1 g/t gold, and till

samples with up to 1,049 gold grains—it also features multiple high-grade* antimony anomalies at the

Swanger's Cove and Le Pouvoir prospects with bedrock and channel samples assaying between 20.4%

and 74.4% Sb (shown on map in Figure 1).

With Chinese export restrictions of antimony

set to take effect September 15, 2024

the high-grade

occurrences of the critical mineral on the Company's Golden Baie Project take on new significance.

High grade antimony discoveries at the Le Pouvoir Prospect include a bedrock vein with assays up to

74.4% Sb and 24.1 g/t gold

, channel samples assaying between

20.4% Sb and 58.8% Sb

, and a

historical drill intercept assaying

30.6% Sb over 1 m

. In 2024, Canstar staked an

additional 1,100

hectares

of prospective mineral claims surrounding the Le Pouvoir gold-antimony prospect. At the

Swangers Cove Prospect, a historical bedrock sample taken by a local prospector from one of the semi-

massive to massive veins assayed 30.1% Sb.

Highlights

Antimony can be a pathfinder to gold and is targeted as part of the gold-focused exploration at

Golden Baie

Canstar's gold-antimony exploration targets at Golden Baie exhibited assays of 74.4% Sb and

24.1 g/t gold in bedrock vein within 90 km of the past-producing Chinese-owned Beaver Brook

Antimony Mine

Antimony is a critical mineral of special importance to defense and national security, and the

majority of the world's production has been controlled by Russia and China

China's announced antimony export restrictions take effect September 15, increasing risk of

supply shocks, given the West's high net import reliance on China and few Western sources

Antimony prices have already doubled this year, with some experts forecasting a rise to over

USD$30,000 per tonne

Additional details on the antimony showings, including photographs, maps and sampling

information, are included below

*High-grade being defined as greater than 20% Sb metal content.

Canstar's President & CEO, Juan Carlos Giron Jr., said, "In sufficiently high grades and quantities,

antimony can create enhanced economic potential for a mine. We think the Project already displays

geological and structural similarities to significant gold producers such as the Fosterville Mine in the

Bendigo Zone of Australia's Victorian Goldfields, which hosts multiple gold deposits greater than 5 Moz

and is analogous to Golden Baie's geological setting. These antimony showings add to our excitement

about the Prospect's potential.

"As critical minerals are increasingly used as a source of geopolitical leverage—exemplified in China's

impending restrictions on antimony exports—the discovery of new sources in the West is a national

security imperative. I believe the junior exploration sector will continue to play a vital role in identifying

new mineral resources which enhance national security and competitiveness."

Antimony's Significance to National Security

Antimony is a Critical Mineral for US and Canadian national security with special importance for the

defense industry, particularly for armour-piercing ammunition and other projectiles, night vision goggles,

infrared sensors, and precision optics. It is also used to produce flame-retardant materials,

semiconductors, cables, and batteries.

In a move to constrain global critical mineral supply in the name of its own national security,

China

announced that it will restrict antimony exports starting on September 15

. China is the world's largest

producer of antimony, accounting for 48% of global production and 63% of US imports according to a

recent

publication by the Center for Strategic & International Studies, a leading Washington DC think

tank

. With the impending restrictions, the likelihood of antimony supply disruptions increases

significantly.

Gracelin Baskaran, Phd, Director of the think tank's Project on Critical Minerals Security wrote

,

"Antimony prices are expected to rise sharply following China's announcement of export restrictions.

Prices have already doubled since the start of the year, reaching an all-time high of

$22,000

per metric

ton. Some experts predict that prices could reach as high as

$30,000

per metric ton as buyers stockpile

and secure supply for future production."

High-Grade Antimony Potential at Golden Baie

In 2023, Canstar geologists removed thin overburden from a portion of the semi-massive to massive

stibnite vein (the host mineral for antimony and gold) at the Le Pouvoir target at Golden Baie, exposing it

over approximately 25 metres of its length (Figure 2), and collected five channel samples across its

width, ranging from 12 cm to 40 cm. These assayed between 20.4% Sb and 58.8% Sb. Historical rock

grab samples of the Le Pouvoir stibnite vein collected by a local prospector assayed up to 74.4% Sb

(sample # CC-18-03 collected in 2018).

Grab (rock) and soil samples are selective by nature and are unlikely to represent average grades on the

property. These results are preliminary and not conclusive evidence of the likelihood of the occurrence of

a mineral deposit. However, these samples indicate that there is significant antimony mineralization

potential on portions of the Golden Baie Project.

The nearby Chinese-owned Beaver Brook Mine—89 km to the northeast, on care and maintenance

since January 2023—processed up to 160,000 tonnes of antimony ore per year with an average grade

of 3.5% Sb (according to data available from 2008-2012), and was considered one of the world's largest

antimony deposits outside of China (

Geological Survey of Newfoundland and Labrador, 2018

).

An earlier sample of the Le Pouvoir vein, taken by Mountain Lake Resources Inc. in 2010, returned

values of 34.9% Sb and 24.1 g/t Au. In 2010, Mountain Lake Resources Inc. also intersected the vein in

a diamond drill hole (LR-10-16) at a depth of 24.3 m containing 30.6% Sb over a 1 m interval. Other

samples of the Le Pouvoir bedrock vein have assayed more than 20% Sb.

In 2022, Canstar also dug a series of trenches on its Swangers Cove Prospect, exposing semi-massive

to massive stibnite veining in three trenches. Five bedrock grab samples from these trenches assayed

more than 1% Sb (the maximum detection limit for the analysis), as did several other float rock samples

found at Swangers Cove, the bedrock source of which remains unknown. A historical bedrock sample

taken by a local prospector from one of the semi-massive to massive veins assayed 30.1% Sb. An

example of the antimony veining found at Swangers Cove is shown in Figure 3.

Canstar has also encountered anomalous antimony assays in samples from its Hermitage prospect in

the far western part of Golden Baie and plans to continue to test for antimony and other critical minerals,

in addition to gold, during its next phase of exploration and drilling.
