Canstar Ramps Up Critical Minerals Exploration With Initial Payment from $11.5M Strategic Exploration JV

/EIN News/ -- TORONTO, May 27, 2025 (GLOBE NEWSWIRE) -- (TSXV: ROX) (OTCPK: CSRNF) Canstar Resources Inc. is ramping up critical metals exploration in Newfoundland with the receipt of the initial $500,000 tranche of its previously announced $11.5M strategic exploration joint venture with VMS Mining Corporation (“VMSC”). The non-dilutive investment positions Canstar to aggressively pursue the discovery of new, high-grade polymetallic (copper-zinc-lead-gold-silver) mineralization at its Buchans and Mary March volcanogenic massive sulphide (“VMS”) projects, located in one of Canada's most prolific historic mining camps.

“We have made meaningful progress. We are fortunate to operate in Newfoundland, where the exploration-friendly permitting process underpins our ability to move quickly and decisively,” said Juan Carlos Giron Jr., President & CEO of Canstar Resources. “This initial $500,000 investment allows us to ramp up work immediately, without the issue of new share capital, and signals strong commitment from VMSC’s leadership and technical team. The Buchans District has hosted some of the world’s highest-grade VMS deposits.¹ Our teams believe the project area holds enormous exploration potential based on historic production and current geological indicators.”

• $500,000 received to commence Phase 1
• Key permits received for trenching and airborne geophysics
• Total Phase 1 investment: $1.5M (asset-level) for 10% JV stake, valuing the JV projects at $15M pre-money
• Industry-leading VMS geologist Dr. Harold Gibson is leading the exploration activities
• Work underway: Deep IP geophysics continues at Buchans; Mary March to commence with geophysics surveys, trenching, mapping and advanced 3D data modeling for target generation
• Canstar retains 100% ownership of its Golden Baie gold-antimony project

Under the agreement, VMSC can earn up to 60% ownership of the JV through optional follow-on investments totaling $10 million across Phase 2 and Phase 3. Canstar retains the right to participate pro-rata in future phases to maintain a significant ownership position.

Historic Mining Pedigree: Additional Information on Canstar’s Buchans and Mary March Projects

Canstar’s Buchans and Mary March Projects are located in the Buchans-Roberts Arm Belt of west-central Newfoundland, Canada. Recognized as one of the highest-grade VMS systems in history, Buchans was mined by ASARCO from the 1920s to the 1980s. Five deposits yielded 16.2 million tonnes with average mill head grades of 14.51% zinc, 7.56% lead, 1.33% copper, 122 g/t silver, and 1.37 g/t gold² (these deposits are not on Canstar Claims and are described to indicate the potential of the area).  

Canstar’s Buchans Project sits immediately adjacent to the historic Buchans mines, all 5 deposits are within 0 to 2,500 m of the Canstar licenses. New 3D geological modelling (2024) by Canstar suggests that the Buchans River Formation, the geological host unit for all five historic Buchans Mine deposits, underlies Canstar’s Buchans property at depth. It is possible, but not certain, that deposits similar-to those mined nearby at Buchans occur beneath Canstar’s Buchans-area claims.

A SkyTEM time-domain electromagnetic survey in 2017³ identified several multi-kilometre geophysical anomalies within Canstar’s Buchans claims. The anomalism coincides with an area of low magnetism, indicating a potential alteration zone. A historic drillhole from the 1970s—located within one of these anomalies—intersected what was described as “stockwork style” mineralization. Stockwork zones typically exhibit a geophysical signature characterized by low magnetism, variable (generally poor to moderate) electrical conductivity, and good chargeability. These characteristics are similar to the geophysical attributes of the stockwork zones of the historic Buchans deposits, suggesting the potential discovery of stockwork and alteration zones associated with Buchans-style VMS deposits.

Canstar’s Mary March project—25km east of the historic Buchans mines—hosts a large mineralized system with alteration zones similar in scale to those at Buchans and high-grade massive sulphides. Historic drilling intersected a faulted-off massive sulphide lens 9.63 m thick, assaying 0.64% Cu, 1.8% Pb, 10.1% Zn, 4.2 g/t Au, 122 g/t Ag.⁴ Canstar trenching in 2019 identified Buchans-style debris flow deposits with massive sulphide clasts, which assayed up to 5.7% Cu, 1.6% Pb, 1.8% Zn, 29.4 g/t Ag, 1.2 g/t Au.⁵
