Canstar Launches Geophysics Program to Unlock High-Grade
Potential of Historic Buchans Mining District, Announces Total
of More than C$550,000 in Warrant Exercise Proceeds, and
Provides Corporate Update
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
2
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 th is 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 includ ing 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 th is 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 hi s service in this role. Additionally, t he 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). He has 20 years of experience in grassroots mineral exploration in
Newfoundland, has been with Canstar since 2018 , and has served as Senior Geologist since
September 2020, conducting exploration on the Buchans and Mary March base metals projects and
the Golden Baie gold project. Mr. Patey was previously a Research Geologist at Altius Resources Inc.,
responsible for identifying and advancing early-stage mineral exploration opportunities.
Mr. Norred is a senior mining professional with over 45 years of experience in geological database
management, resource modeling, open- pit mine design, software development, and project
management. He has designed, developed, and served as an expert user of major software packages
for the minerals industry. In 1982, he founded Techbase International, and for the past 43 years, he
