VANCOUVER, BC, July 12,
2022 /CNW/ - Zacapa Resources (TSXV:
ZACA) (OTCQB: ZACAF) (DE: BH0) provides an update of
exploration activities to date at its 100% owned Pearl porphyry
copper project adjacent to BHP's past-producing San Manuel-Kalamazoo porphyry copper mine in
Arizona (1,390 Mt at 0.6% Cu,
0.011 % Mo, 0.017 g/t Au, 1.8 g/t Ag)1,2. Zacapa
Resources has identified a window of porphyry copper prospective
Laramide-age igneous rocks situated immediately north of
San Manuel-Kalamazoo and completed
a systematic campaign of geochemical and geophysical surveys across
the property to identify and advance the most prospective targets
to the drill testing phase.
Highlights
- Geologic mapping at Pearl demonstrates propylitic alteration
and a fault architecture similar to the San Manuel-Kalamazoo deposit
- Previously unknown Laramide age porphyry dikes identified by
Zacapa (U/Pb geochronology) overlap with the age of the adjacent
1,390 Mt San Manuel-Kalamazoo porphyry copper deposit
- Initial geochemical and geophysical surveys revealed multiple
anomalies for follow-up, including two large, copper-in-soil
anomalies with up to 1415 ppm Cu
- Numerous, previously undocumented, historic mine workings
identified during field mapping with mineralized rock samples
containing up to 7.3% Cu, 0.43% Mo, 19.9% Pb, 4.9% Zn, 360 g/t Ag,
and 1.8 g/t Au
"The presence of copper mineralization at surface and
prospective Laramide age intrusions on the Pearl property represent
a significant step forward for the project. The Pearl project
contains favorable host rocks in a newly identified window of
Laramide igneous activity only one kilometre from BHP's 1.39
billion tonne San Manuel-Kalamazoo
porphyry copper deposit," comments Adam
Melnik, CEO and Director. "Zacapa's technical teams are
actively progressing the project toward drill testing, which will
be an important step towards unlocking latent value from within
Zacapa's portfolio."
Since acquiring the Pearl project by claim staking in 2021,
Zacapa has initiated exploration by completing reconnaissance scale
mapping, sampling, and geophysical surveys. A 346 line-km Z-axis
Tipper Electromagnetic (ZTEM) and aeromagnetic geophysical survey
(200-metre line spacing) was conducted in June 2021, followed by initial mapping and
rock/soil sampling in December 2021.
Geological mapping of the property revealed a fault-bound inlier of
Proterozoic and Cretaceous igneous rocks surrounded to the east and
west by post-mineralization volcanic and sedimentary cover rocks
(Figure 1). The same post-mineral faults displace the western
(Kalamazoo) half of the San
Manuel-Kalamazoo orebody concealing it beneath younger
post-mineral cover3.
At Pearl, the basement (Proterozoic) rocks are locally
overprinted by propylitic (chlorite-epidote-carbonate) alteration,
which is common feature in distal porphyry hydrothermal systems.
The propylitic alteration occurs in several areas along a NW-SE
trending zone roughly parallel to the San
Manuel fault that bisects the San
Manuel-Kalamazoo orebody (Figure 2). Mapping also identified
Laramide age porphyry dikes which Zacapa dated, obtaining
preliminary U-Pb ages of 71 ± 8 Ma and 73.5 ± 6 Ma. These age dates
are significant and encouraging as they are the first documentation
of Laramide age dikes on the property and their ages coincide with
the timing of formation of the San
Manuel-Kalamazoo copper deposit (approximately 68
Ma2).
Reconnaissance soil sampling (n = 108) was conducted on a 400 x
400 metre grid over areas not overlain by post-mineral cover.
Numerous highly anomalous copper and molybdenum bearing samples
were observed, with up to 1415 ppm copper, 674 ppm molybdenum, 4860
ppm lead, 2580 ppm zinc, and 1.46 g/t silver (Figure 2). At least
two large, anomalous copper-in-soil footprints have been
identified, each measuring greater than 1 km by 1 km. Follow up
soil sampling will be required to refine the anomalies. Rock chip
and grab samples (n = 50) were collected throughout the area
including from 26 mineral occurrences documented during mapping
(Figure 3). Mineralized samples display high concentrations of
copper (up to 7.3%), molybdenum (up to 0.43%), lead (up to 19.9%),
zinc (up to 4.9%), silver (up to 360 g/t), and gold (up to 1.8
g/t).
About the Pearl Porphyry Copper
Project
The Pearl porphyry copper project is in the San Manuel Mining
District, less than a kilometre north of BHP's past-producing
San Manuel-Kalamazoo deposit
(1,390 Mt at 0.6% Cu)2. Pearl is comprised of 241
unpatented mining claims covering 4,983 acres (20.2
km2). The Pearl project area exhibits widespread
mineralization associated with epithermal veins, including the
historic Pearl mine with visible copper mineralization over more
than 800 metres at surface. Propylitic alteration observed in the
area is permissive for the presence of an underlying porphyry
hydrothermal system. Exploration is focused on utilizing alteration
and geochemistry of exposed outcrops along with advanced structural
interpretations and geophysics to develop drill targets beneath
post-mineral cover. Zacapa is one of the only exploration companies
drilling for porphyry copper in southeast Arizona, which is dominated by Freeport, BHP, and Rio Tinto.
About Zacapa
Resources
Zacapa is a copper and gold focused mineral exploration company
engaged in responsible exploration for the new energy economy. Its
projects are concentrated in world class jurisdictions in the
