IP Survey on Mystery Property Outlines Porphyry Targets
IP Survey on Mystery Property Outlines
Porphyry Targets
Vancouver, British Columbia--(Newsfile Corp. - July 13, 2026) - Rokmaster Resources Corp. (TSXV:
RKR) (OTCQB: RKMSF) (FSE: 1RR1) ("Rokmaster" or "the Company") is pleased to provide an update
on exploration activities on the Mystery Property.
In June, SJ Geophysics completed an Induced Polarization Survey ("IP Survey") over several porphyry
Cu-(Mo±Au) targets on the Mystery Property. The IP Survey was a pole-dipole active array capable of
investigating chargeability and resistivity down to depths of 300-500 m with the purpose of refining
targets planned for drill testing during the fall.

.
The southern IP Survey profile, Line 1000, was completed over the B2 and B3 zones. This area features
limited outcrop exposures of strongly potassic-altered andesite hosting a dense stockwork of pyrite-
chalcopyrite-biotite-magnetite veinlets which have returned elevated copper, molybdenum, and gold in
rock sample assays. The IP response shows a strong high chargeability anomaly cored by a strong high
resistivity anomaly below and southeast of the B2 Zone
(Figure 3)
.
Approximately 2.5 km to the northeast, IP Line 2000 investigated a coincident soil and magnetic
anomaly in the northern portion of the Ford Anomaly area. This area is underlain by rhyolite belonging to
the Kasalka Group which displays strong phyllic alteration over a broad area including intense sericite
replacement and disseminated pyrite. Hyperspectral work completed in the previous years indicates that
higher-temperature paragonite occurs below a certain elevation in the Ford Anomaly area indicating
good potential remains at depth. IP Line 2000 outlined a large and broad high chargeability anomaly
~200 m below the western portion of the profile, and a deeper highly resistive feature on the eastern end
of the profile
(Figure 4)
.
Another ~1.1 km to the north of the Ford Anomaly, IP Line 3000 tested an area of stockwork quartz
veining in sericite- and potassic-altered porphyritic monzonite. This area was discovered last year and
Re-Os age dating on the molybdenite mineralization confirmed that it belongs to the productive late
Cretaceous Bulkley Intrusive Suite which is related to porphyry systems in the region such as the
Huckleberry, Ox, Seel, and Poplar Deposits. IP Line 3000 shows a west-dipping coincident high
chargeability and high resistivity anomaly which comes to surface near where the molybdenite
mineralization outcrops. Possibly related to line 2000, there is also a deeper highly resistive feature in
the eastern portion of the Line 3000 profile
(Figure 5)
.
Diamond drilling of several of these targets, now refined at depth with the IP Survey, is being planned for
September-October 2026. The Mystery Property holds an active three-year exploration permit and
Rokmaster is fully funded to complete the drilling as planned.
John Mirko, President and CEO, comments:
"The IP Survey will certainly improve the efficiency of the planned drilling with the specific drill targets
now resolved at depth. The Mystery Property and the region in general does not offer much outcrop
exposure so we are fortunate to have discovered several occurrences of significant porphyry-style
alteration and mineralization. Now the IP Survey has detected multiple very encouraging features at
the drill targeting scale. The whole team is thrilled with these results, especially on line 1000, and is
excited to get a drill turning on them later this year."
Nechako Project
The Mystery Property is a part of the Company's Nechako Project, which totals 28,238 hectares (282
km
2
) across four properties located in west-central British Columbia. The Nechako Project features
multiple exploration targets for significant porphyry Cu-(Mo±Au) mineralization and high-grade Au-Ag
vein systems in the southern portion of the productive Stikine terrane
(Figure 1)
. Rokmaster has nurtured
the Nechako Project for several years, efficiently vectoring towards robust drill targets on the properties,
three of which hold active exploration drill permits.
