Toronto, Ontario--(Newsfile Corp. - March 3, 2025) - CANSTAR RESOURCES INC. (TSXV: ROX) (OTC Pink: CSRNF) ("Canstar" or "the Company") announces the commencement of a geophysics program aimed at exploring new, high-grade precious and critical metals deposits within the historic Buchans mining district. The program will leverage Abitibi Geophysics' advanced DasVision 3DIP system to refine drilling targets by identifying stockwork zones and related alteration and mineralization consistent with potential Buchans-grade VMS mineralization at depth. Stockwork zones are historically associated with higher-grade massive sulphide lenses in the Buchans area. The survey will build on previous exploration efforts in the Buchans district, including a district-scale SkyTEM survey.
Historic Buchans VMS District
Long recognized as one of the highest-grade Volcanogenic Massive Sulphide (VMS) systems in history, Buchans was mined by ASARCO from the 1920s to the 1980s. Five deposits yielded a total of 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 gold.
New geological modeling (2024) by Canstar indicates that the Buchans River Formation, the geological host unit for all five historic Buchans Mine deposits, may underly Canstar's entire property at depth. The formation plunges from the historically mined deposits towards Canstar's adjacent Buchans-area claims.
The 2017 SkyTEM electromagnetic survey identified several multi-kilometre geophysical anomalies within Canstar's Buchans claims. The anomaly coincides with an area of low magnetism, indicating a potential alteration zone. A single historic drillhole from the 1970's-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, which is detected by the DasVision system. 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.
VMS deposits are among the most extensively studied mineral deposit types and have well-understood architectural characteristics. The historic Buchans mines are an appropriate analogue for new discoveries within the belt. The massive sulphide deposits at Buchans are dominated by non-conductive sphalerite and contain low pyrite content, making them difficult to detect using electromagnetic geophysical techniques. However, the surrounding alteration and stockwork zones are typically much more extensive and contain zoned distributions of pyrite and chalcopyrite, more easily identifiable through induced polarization survey methods.
By detecting isolated chargeable grain boundaries of conductive minerals, such as the disseminated sulphides associated with large parts of the stockwork and alteration zones, Abitibi's DasVision 3DIP system has the potential to map stockwork zones and aid in locating the higher-grade massive sulphide "core" of a hydrothermal system. The DasVision 3DIP system is capable of resolving the 2017 SkyTEM anomalies at relevant depths, mapping them in 3D, and generating high-priority drill targets to drive a breakthrough discovery in this historic district. The Buchans district's unique geology, which lacks the distorting effects of graphite and pyrrhotite, provides ideal conditions for deploying this technology to maximum effect.

Additional Survey Details
The 3DIP DasVision will cover approximately 11.76km2 of Canstar's mineral license in the Buchans area, extending onto Canterra Mineral Corporation's adjacent mineral claims. This comprehensive survey will provide a deep depth of investigation for targets identified in previous airborne and ground-based geophysical surveys, while also offering the potential of new discoveries. The survey is a joint collaboration between Canstar and Canterra, with anticipated synergies including the improved detection at depth that comes with a larger survey array, an expanded dataset for both companies and reduced mobilization and demobilization costs.
The DasVision 3DIP survey for Canstar will deploy an array of FullWaver receivers arranged in a 600m x 600m mesh, with currents injected at 200m intervals between and around the receivers. Additional transmitter (Tx) rows with expanding currents will be added along to the eastern edge of the block to help increase the depth on the down dip edge of the grid. Optimally designed for investigating large, deep-seated targets, the survey aims to detect disseminated sulphides and/or stockwork zones that may be associated with a massive sulphide deposit.
Corporate Update
Canstar has received additional proceeds of C$141,975.15 from the exercise of 2,839,503 warrants, bringing total proceeds from the exercise of warrants issued in the January 2024 financing to C$551,975. To date, 11,039,503 warrants have been exercised out of the 26,665,500 warrants issued in the January financing. The Company believes the early exercise of these warrants demonstrates strong commitment and continued support from large shareholders.
The Company is also pleased to announce that its board of directors has appointed Mr. Bob Patey as Vice President of Exploration and Qualified Person, effective March 1, 2025. Mr. Paul Ténière will transition from this role to support the Company as a member of its Advisory Board. This planned transition further empowers and streamlines the Company's operations in Newfoundland while retaining Mr. Ténière's valuable in-house advice. The Company benefited from his guidance and expertise, and thanks him for his service in this role. Additionally, the Company is pleased to announce the appointment of Mr. Michael Norred to its Advisory Board.
Mr. Patey holds a B.Sc. Honours in Geology from Memorial University of Newfoundland and is a Professional Geologist registered with the Professional Engineers and Geoscientists Newfoundland & Labrador (PEGNL).
