ORESTONE PREPARES FOR AIR MT SURVEY
AT
CAPTAIN GOLD PORPHYRY PROJECT, BC
Orestone Mining Corp. (TSXV: ORS) (OTC: ORESF) (Frankfurt: WKN: O2R2) (“the Company”) is
pleased to announce that it is planning an airborne MagnetoTelluric (AirMT) survey to cover the partially
defined, T-2 conductivity target at the Company’s 100 percent owned Captain Gold Porphyry Project in
North Central BC prior to the next drill programe . The project is located 40 kilometres north of Fort St.
James and 30 kilometres south of Mt . Milligan, a large open pit copper-gold mine. The T-2 target is the
southernmost target zone outlined on the property to date. The Company is obtaining contractor quotes and
refining the parameters of the survey at this time. Initially the new survey will consist of 18 lines at 7.2
kilometres in length totalling 157 line kilometres and we expect to complete the program in the summer of
2025.
The Captain Project hosts a gold dominant porphyry style mineralized system occurring within a 5
kilometre long, N-S trending corridor of low resistivity defined by a 2022 AirMT survey (for larger maps
click here). Three targets occur at the intersection of interpreted northeast and northwest trending cross
faults. This type of low resistivity feature is often related to large porphyry systems. Also gold rich porphyry
systems such as Red Chris mine in northeastern British Columbia are typically strongly structurally
controlled and are characterized by a narrow zone of multiple intrusive dyke phases widening at depth with
a halo of copper-gold rich disseminated sulphides and quartz stock works overlying the dyke system.
The T-2 anomaly is similar in intensity to the T-1 target. The central T1 target, an extensive 2 X 2 kilometre
tabular zone of porphyry style alteration hosts zones of sericite-potassic-feldspar alteration containing gold-
copper mineralization from 20-160 metres thick grading 0.20 to 0.84 g/t gold and 0.05 -0.11 percent (500-
1100 ppm) copper. Drill core logging has identified altered and mineralized porphyry dykes, both in the

hanging wall and dipping into the observed MT conductor implying the presence of a potential intrusive
porphyry system. It is thought to be highly probable that the next phase of drill holes will intersect a gold-
copper porphyry intrusive system with mineralization similar to that found in the overlying dykes and
volcanics.
David Hottman, Orestone's CEO, stated: “Orestone’s property portfolio includes exploration exposure to gold, silver
and copper in Canada and Argentina. The Company’s primary asset is the 100 percent owned Captain gold -copper
project in North Central BC which hosts a large gold dominate porphyry system; permitted and drill ready. The gold
discovery potential of Captain has attracted large producers Centerra Gold, IAMGOLD and New Gold to stake claims
almost completely surrounding the property. Earlier stage projects in the portfolio include the Las Burras copper-
gold project and the Francisca gold-silver project. Both are earn-in options in Salta Province Argentina and provide
scaled exploration exposure to the Company. Orestone employs advanced geological and geophysical techniques in
our exploration programs and plans to complete an AirMT survey to cost effectively define the conductive porphyry
targets so that they can be systematically drill test ed. All of these high potential projects have a relatively low-cost
profile to hold and explore and are suitable for exploration year-round. Orestone’s exposure to gold, silver and copper
projects could well reward shareholders should a large discovery be outlined. ”
The drill intercepts to date from Captain demonstrate a well mineralized system . Below are previously
released results.
