Sun Summit Identifies New Zone of Copper
Mineralization Near CR; Completes Expansion
Drill Program at Buck Main
Vancouver, British Columbia--(Newsfile Corp. - September 19, 2023) - Sun Summit Minerals Corp.
(TSXV: SMN) (OTCQB: SMREF) is pleased to announce surface sampling results from the summer
2023 exploration program at its flagship Buck Project in central B.C. The field campaign focused on
exploration at several high-priority targets at the Mount Morice and CR areas and resulted in the
discovery of a new zone of copper mineralization.
Highlights:
Strong copper mineralization:
Rock samples returned results up to
1.00% Cu and 3.2 g/t Ag,
and 0.94% Cu and 4.1 g/t Ag
in a new zone that has seen limited exploration. Target areas show
strong porphyry-related mineralization and alteration and remain open for expansion.
Exploration aimed at discovery:
Reconnaissance field work included detailed mapping,
sampling, and prospecting around the Mount Morice and CR target areas.
Completion of step-out drill program at Buck Main:
The drill campaign consisted of 3,736
metres over 13 diamond drill holes in high-priority areas aimed at testing the lateral and vertical
extents of mineralization (see
June 8, 2023
, news release). Assays have been released for the first
two holes of the program, and remaining assays are being processed at the lab and will be
released as they are received and interpreted.
Sharyn Alexander, Sun Summit's President stated: "We are very pleased with the results from our initial
exploration efforts at CR, as well as follow-up exploration at Mount Morice. Both of these targets have
shown notable mineralized occurrences through previous exploration and warrant detailed systematic
follow-up. The detailed geological mapping and geochemical sampling will allow us to continue to define
these targets and advance them towards the drill-ready stage. The results provide evidence of the
project's ongoing potential for expansion and discovery of new mineralized zones."
Exploration Program
Extensive surface exploration was conducted in the area of Mount Morice and the newly acquired CR
project (see
June 1, 2023
news release). This work included detailed geological mapping, sampling,
and prospecting, with a total of 230 surface samples collected in high-priority areas (203 rock samples,
17 silt samples, and 10 soil samples). See Figure 1 for selected highlights from recent and historic
exploration programs.

Rock sample highlights from the 2023 program include:
Sample J031024:
1.00% Cu & 3.2 g/t Ag, rhyolite/andesite breccia with strong silicification
and copper oxide alteration
Sample J030700:
0.94% Cu & 4.1 g/t Ag, similar to sample J031024, strongly Cu-oxidized
rhyolite
Sample J030681: 0.64% Cu & 8.1 g/t Ag, drusy quartz veins with disseminated chalcopyrite and
strong copper oxides in epidote altered rhyolite
Sample J030756: 0.39% Cu & 2.1 g/t Ag & 81 g/t Mo, hydrothermal breccia with disseminated
pyrite ± chalcopyrite-molybdenite and moderate Cu oxides
Other significant copper results from the 2023 program include:
Sample J030746: 0.36% Cu
Sample J030667: 0.30% Cu
Sample J030755: 0.19% Cu
Sample J030713: 0.19% Cu
Sample J030718: 0.18% Cu
Sample J030719: 0.17% Cu
The Mount Morice target is one of a number of high-priority targets selected for follow-up. This key area
is located approximately eight kilometres west of Buck Main on the eastern slopes of Morice Mountain.
Field work at Mount Morice included geological mapping, prospecting, and infill silt sampling. Stream
sediment samples from eastern drainages on Mount Morice, downslope from the mapped alteration and
vein zones, display highly anomalous gold and silver. Samples from 2022 exploration returned results
well above background based on regional stream sediment sampling programs, including
0.26 g/t Au
and 0.6 g/t Ag
(sample F193428), and
0.25 g/t Au and 0.4 g/t Ag
(sample F193427; Figure 1). These
results, together with results from mapping and previous selective sampling (see
March 1, 2023
news
release), suggest the potential of a high-level epithermal system peripheral to a porphyry system. The
anomalous gold+silver in silt samples are downstream of widespread propylitic alteration and local
zones of strong phyllic alteration with associated quartz stockworks and sulfide-cemented breccias.,
The CR area adjoins the Buck project on its western edge and expands the overall property footprint for
a contiguous area of 55 mineral claims totalling 52,000 hectares (520 square kilometres). This year
represented the first time the CR area was accessed by Sun Summit after its acquisition (see
June 1,
2023
news release), and consisted of a first pass reconnaissance assessment of the geological
environment and the known zones of mineralization.
A large IP chargeability anomaly, located in the northern section of CR at the North Zone, has seen
limited exploration. The anomaly is associated with strong zinc in soils, as well as historic rock samples
that have returned values of up to
0.4 g/t Au and 31.7 g/t Ag
(sample 3233760; Figure 1).
Previous exploration campaigns in the CR area included soil, rock, and silt sampling, airborne and
ground geophysics, as well as diamond drilling. The most significant drill intercepts to date are reported
from the South Zone, and include
68 metres

at 0.50% Cu, 0.015% Mo
in CR05-03; and
168 metres
at 0.37% Cu, 0.017% Mo
in CR07-14

.
The CR area contains priority targets that warrant detailed systematic follow-up. All known targets show
strong porphyry-related mineralization and alteration (distal and proximal assemblages) and are open for
expansion.
Drill Program Completion
The expansion drill program at Buck Main has been completed, consisting of 13 drill holes for 3,736
metres. These holes were targeting new zones of potential high-grade and bulk-tonnage mineralization
in previously untested areas, both laterally and at depth. Updated 3D modelling at Buck Main led to an
improved understanding of the geological and structural controls of mineralization, and drill holes were
designed to test fault structures and veins that are often associated with high-grade mineralization
elsewhere within the Buck Main zone.
Initial drill results indicated significant gold, silver, and zinc mineralization extend laterally and at depth,
and support the potential for depth extension of bulk tonnage-style disseminated mineralization being
delineated at Buck Main (see
September 6, 2023
news release).
The remaining drill holes are being processed for assay and geochemical analysis at the lab. Analytical
results will be reported as they become available and undergo QA/QC.
Quality Assurance and Quality Control
All sample assay results have been monitored through the Company's quality assurance / quality control
(QA/QC) program. All sample assay results have been monitored through the Company's quality
assurance / quality control (QA/QC) program. Rock, silt and soil samples collected in the field were
placed in polyethylene bags (rocks), kraft paper sample bags (soils), and spunbonded polyester fabric
bags (silts). UTM coordinates of sample locations were recorded using a handheld Garmin GPS device.
For soil samples, sample locations were marked in the field with coloured flagging tape with unique
sample number identifiers. Rock grab samples were marked using metal tags with unique coloured
flagging tape and unique sample numbers. The samples were brought from the field daily to the
Company's secure core logging facility in Houston, B.C.
After drying the samples were organized by sample number and type and secured with tamper-proof
security seals in rice bags for shipment. Samples were shipped by bonded courier Bandstra
Transportation Systems Ltd to ALS Global preparation facilities in Kamloops, B.C., and then on to the
ALS Global analytical laboratory in North Vancouver, B.C. for analysis. ALS Global is registered to ISO /
IEC 17025:2017 accreditations for laboratory procedures. Rock silt and soil samples were prepared at
the lab using standard analytical preparation procedures, including weighting and screening, and for
rocks, crushing, pulverizing and splitting.
Rock samples were analyzed for 33 elements by ICP-MS on a 0.25-gram aliquot using a four-acid
digestion (method ME-ICP61). Gold was analyzed by fire assay on a 30-gram aliquot with an AAS finish
(method Au-AA23). Samples with >10 parts per million (ppm) gold were re-analyzed by fire assay using
a gravimetric finish on a 30-gram aliquot. Samples with >100 ppm silver were re-analyzed using an ore -
grade four acid digestion and ICP-AES finish. Samples with >10,000 ppm zinc were re-analysed using
an ore -grade four acid digestion and ICP-AES finish.
Soil and silt samples were analysed for gold and silver only. Gold was analyzed by fire assay on a 30-
gram aliquot with an AAS finish (method Au-AA23). Silver was analyzed using aqua regia digestion
followed by an AAS finish (method Ag-AA45).
In addition to ALS Global laboratory QA/QC protocols, Sun Summit implements a rigorous internal
QA/QC program that includes the insertion of duplicates, standards and blanks into the sample stream.
