Canstar Resources Inc. Re-initiates District-Scale Precious & Critical Metals Exploration

Exploration Highlights

Golden Baie

• Spring 2024 prospecting of the under-explored Woodcutter Prospect along the Little River Trend collected over 300 combined soil and grab rock samples; over 60% of the rock samples demonstrated anomalous gold results above 100 ppb gold; several float grab samples returned significant assay results including 11.8 g/t, 3.1 g/t, and 1.8 g/t gold.

• A re-evaluation of data previously acquired by Canstar, and historical data, has identified 13 priority exploration targets, including Facheux Bay with up to 18.4 g/t gold in bedrock, Le Pouvoir with up to 74.4% antimony and 24.1 g/t gold in a bedrock vein, and Blowout East with a high-grade large boulder sample grading 197 g/t gold over 0.5m.

• Commenced new 3D geological modelling of the Kendell Prospect, where notable drilling intercepts from Canstar's 2022 drilling program included 9.6 g/t gold over 7.8m, 20.6 g/t gold over 3.5m, and 58.2 g/t gold over 1.1m.

• Staked an additional 1,100 hectares of prospective mineral claims surrounding the Le Pouvoir antimony/gold prospect expanding coverage within the highly anomalous Little River Trend for a total current area of 548.75 km² at Golden Baie.

Buchans

• Completed new 3D geological model indicating significant potential that the deposit-hosting Buchans River Formation may underlie Canstar's Buchans mineral claims.

• Historical mining by ASARCO of 5 deposits hosted by the Buchans River Formation yielded 16.2 million tonnes with average mill head grades of 14.51% zinc, 7.56% lead, 1.33% copper, 126 g/t silver, and 1.37 g/t gold^(1).

• Newly staked 13 mineral claims in 2 licenses, adding 325 hectares of prospective land near the Skidder deposit south of the historic Buchans Mining District.

CEO Juan Carlos Giron, Jr., said, "In 2023, driven by our belief that the world is on the cusp of a commodities supercycle, we went on a search for the ideal platform from which to capitalize on what we believe is a generational opportunity in metals and mining. Upon being introduced to Canstar, we were immediately excited by the locally-based technical team, its distinguished board of directors, its cornerstone shareholders (Eric Sprott & Altius Minerals Corp.), and its exploration projects, which we believe are situated in highly prospective geological settings in an emerging, world-class mining district.

"Canstar's 100% owned Golden Baie Project was optioned from Altius Minerals (TSX: ALS) in 2020 and features district-scale orogenic gold exploration replete with gold anomalies, including over 315 bedrock samples with more than 1 g/t gold, and combines what we believe is high project prospectivity, low exploration maturity, a deep pipeline of exploration targets, and attractive ease of exploration due in part to the excellent infrastructure in and around the project (Figure 1).

"Canstar also has two projects in the historic Buchans Mining District, known for hosting previously-mined polymetallic (zinc-lead-copper-silver-gold) volcanogenic massive sulphide ("VMS") deposits. The Buchans Project includes mineral licenses with hundreds of metres of historical drilling and great potential to host additional deposits. The Mary March Project, 20 km east of Buchans, is a joint venture with Glencore and has one of the highest-grade drilling intercepts outside of the main Buchans mining camp (Figure 2).

"Following months of assessment, technical review, 3D geological modeling, and new surface exploration, we are excited to announce that Canstar is re-initiating mineral exploration work on its projects. We have cumulatively identified over 50 exploration targets, including high-priority and drill-ready targets at both the Golden Baie and Buchans-Mary March projects, and we will be communicating our plans for advanced exploration soon."

Sampling, QAQC, and Analytical Procedures

Canstar field staff collected all rock samples either from outcrops (bedrock) or as float/boulder samples and put into sample bags with unique sample tags. Field staff recorded the exact location of the collected grab sample using a GPS-enabled tablet and took field notes on lithology, structure, and mineralization. Canstar field staff securely transported rock samples to Eastern Analytical Ltd's (EAL) laboratory in Springdale, NL. EAL is a commercial laboratory that is ISO/IEC 17025 accredited and independent of Canstar. The laboratory crushes the entire sample to 80% 10 mesh (2mm), splits out a 250g subsample which is pulverized to 95% 150 mesh (<0.089mm) from which the fire assay and ICP aliquots are taken. EAL analyzed the samples using fire assay (30g) with AA finish and an ICP-34, four-acid digestion followed by ICP-OES analysis. Field staff collected all soil samples at approximately 25m spacing along 50m to 100m-spaced lines and from the B-horizon soil layer wherever possible. Canstar field staff recorded each soil sample location using a GPS-enabled tablet and placed the sample in a paper bag with a unique sample ID tag. Canstar field staff securely transported the soil samples to EAL for sample preparation, gold fire assay, and 34-element ICP analysis.

Acknowledgements

Canstar wishes to acknowledge the financial support of the Junior Exploration Assistance Program from the Department of Natural Resources, Government of Newfoundland and Labrador, which has been a valuable contribution to the exploration programs on the Buchans-Mary March and Golden Baie Projects.

Cautionary Statements

Please note that soil, till, and rock samples are selective by nature, and values reported may not represent the true grade or style of mineralization at Golden Baie. Readers are cautioned that these potential grades are conceptual in nature; there has been insufficient exploration by the Company or its Qualified Person to define a mineral resource or deposit; and it is uncertain whether further exploration will result in these targets being delineated as a mineral resource.
