Cupani Intersects Magmatic Massive Sulphides in Three New Drill Holes
Cupani Intersects Magmatic Massive Sulphides in Three New Drill Holes
Toronto, Ontario – September 1, 2026 – Cupani Metals Corporation (“Cupani” or the
“Company”) (CSE: CUPA, OTCQB: CUPIF) is pleased to provide an update on its summer
drilling campaign at its Blue Lake Project, located 65 kilometres from ScheƯerville, Quebec.
Of the first four holes drilled this summer, three intersected magmatic massive sulphides at
the base of mineralized ultramafic flows / subvolcanic sills. The newly intersected
mineralization is located more than one kilometre southeast of historical mineralized
lenses. All four holes tested targets within a high-priority corridor that remains open and
largely untested along a strike length of at least sixteen kilometres (10 miles). The newly
intersected massive sulphide horizons, and the general stratigraphy hosting them, are
roughly horizontal.
Highlights
CU26-07: 1.8 meters of magmatic massive sulphides from 208.0 meters.
CU26-08: 0.5 meters of magmatic massive sulphides from 256.35 meters.
CU26-10: 2.45 meters of magmatic massive sulphides from 159.1 meter (see Figure
1 and 2).
Jacquelin Gauthier, VP Exploration, commented: “Our summer drilling program has been
highly successful to date, with 3 of 4 holes intersecting massive sulphides at the base of
the ultramafic units. These results clearly validate our new geological interpretation and
confirm that we are exploring a robust metallogenic system with the potential to produce
thick, significant intersections. ”
CEO Brian Bosse adds: “These holes show Cupani understands how this system is
organized. Intercept thickness should evolve this copper - nickel exploration project from
interesting to evident; it is roughly horizontal and remains open for miles. ”

pyrrhotite is not magnetic.
To date, four diamond drill holes have been completed this summer in the Blue Lake
Southeast sector.
CUP26-07 was designed to test the up-dip extension of the newly discovered mineralized
horizon intersected in hole CUP26-06 (read press release June 3, 2026). It entered a volcano-
sedimentary sequence followed by a 67-meter-thick ultramafic unit with the percentage of
disseminated and blebby sulphides increasing at depth until the massive sulphide horizon
(1.8 meters thick). The hole ended in felsic pyroclastics and a gabbro
CUP26-08 targeted a strong magnetic and EM anomaly, 200 meters to the NW of holes
CUP26-07 (and 6), along the same magnetic trend. This hole started in a volcano-
sedimentary sequence with sulphidic sediments before entering a 150 meters thick
ultramafic unit with magmatic sulphides locally consisting of disseminations and blebs. A
0.5-meter massive sulphide horizon was intersected at the base of the ultramafic and at the
contact with felsic pyroclastics. This hole ended in gabbro.
Hole CUP26-09 targeted coincident weak magnetic and EM anomalies. This DDH was
collared 230 meters NW of hole CUP26-04 on the same magnetic trend. It collared into a
mineralized ultramafic with sulphide disseminations and blebs followed by a sedimentary
and tuƯaceous sequence with sulphides and cherty exhalites. This hole then entered an
ultramafic flow, then a diƯerentiated ultramafic and mafic intrusion that was
unmineralized.
CUP26-10 was collared 244 meters to the SE of hole CUP26-04 on the same magnetic trend,
and 376 meters NE of hole CUP26-07 and 6. This hole started in 29.7 meters of mineralized
ultramafic with disseminated and net textured sulphides, then 23.3 meters of basalt before
entering 89 meters of an ultramafic with percentage of disseminated sulphides increasing
with depth. The next unit intersected was 10 meters of a felsic pyroclastic, then a 0.6-meter
mineralized pyroxenite followed by 2.45 meters of magmatic sulphides and another
pyroxenite unit over 7.3 meters. The hole ended in a gabbro.

Drilling remains ongoing for the next few weeks. The drilling campaign has successfully
confirmed the e Ưectiveness of Cupani’s targeting strategy, with massive sulphide horizons
intersected at the base of ultramafic units. The contacts of the sulphide zones are close to
perpendicular to core axis of the vertical holes and should be considered close to true
thickness. These massive sulphides are overlain by significantly broader intervals of
disseminated, net-textured and blebby sulphides within the overlying ultramafic sequence.
Samples from the best massive sulphides intervals are being sent for rush laboratory
analysis to ALS global in Val d’Or. Assay results are expected in the coming weeks and will
be reported in a subsequent news release.
