Lithium-Bearing Pegmatite Exploration
Program on Its Red Lake Projects
Vancouver, British Columbia--(Newsfile Corp. - May 18, 2023) -
Sonoran Desert Copper
Corporation
(
TSXV: SDCU
) ("
SDCU
'' or the "
Company
") is pleased to announce the Company's
plans for an exploration program on its Red Lake Projects to follow up on historical LCT pegmatite
occurrences. The Camping Lake and Bluffy Lake Projects straddle the boundary between the volcanic-
dominated Uchi subprovince to the north and the metasedimentary-dominated English River
subprovince to the south. Recent exploration has resulted in success for the Company's direct
neighbours to the east along +100 kilometres of the Uchi / English River boundary.
The Company's contiguous neighbour to the east, Kenorland Minerals Ltd. has completed an exploration
program on its South Uchi claims, resulting in multiple lithium-cesium (Li-Cs) anomalies, which could
indicate potential sources of lithium-cesium-tantalum (LCT) pegmatite systems along the Uchi/English
River subprovince boundary within their claims.

Directly east of Kenorland's South Uchi Caims, are the Root Lake and McCombe lithium deposits, held
by Green Technology Metals, which are being developed to resources and straddle the same
Uchi/English River margin.

Brian Leeners, CEO of Prime Meridian, stated, "Our Red Lake claims capture approximately 30
kilometres of the Uchi / English River boundary and the historical showings combined with the recent
success of our neighbours demonstrates the potential for lithium-bearing pegmatite systems within our
Project areas."
LCT Pegmatites at SDCU's Camping Lake Project
The Company's Camping Lake Project covers mapped pegmatite outcrops and remains prospective
over approximately 18 kilometres along a contact of a large granitic batholith and regional greenstone
belt, along the Uchi/English River subprovince boundary, an area highly prospective for LCT pegmatites.
Further to the northeast, the Company's Bluffy Lake Project covers an additional 12 kilometres of the
Uchi/English River subprovince boundary and lies adjacent and on trend with Kenorland Minerals' South
Uchi claims.
The Camping Lake Project encircles a large granitic batholith, which intrudes into greenstones of the
Uchi subprovince. The southern part of the claim area covering the Sydney Lake Fault Zone (SLFZ)
straddles a sequence of interbedded greenstone metagreywackes and metavolcanics in the north and
iron formation and metagreywacke in the south, with parallel granitic intrusive contacts mapped near the
centre and southern part of the claims, trending parallel to the regional SLFZ fault zone.
The rocks in the area have been intruded by granitic rocks of at least three ages and mafic dikes,
stocks, and batholiths. Underlying part of the property is a muscovite-biotite granodiorite, which suggests
the possibility of a sedimentary-granitic complex. The rocks exhibit heterogeneity in grain size, ranging
from medium- to coarse-grained with some fine-grained facies. Associated with the granodiorite are
aplite and pegmatite dikes. Aplite dikes are fine-grained and a few centimetres wide, composed of
leucocratic quartz-feldspar rocks. On the other hand, pegmatite dikes can reach widths of 3 metres or
more and have variable composition and grain size, often with sharp or gradational contacts.
Historical Pegmatite Showing
Near the edge of the Company's Camping Lake Property, near Highway 105, there is sparsely
distributed beryl mineralization occurring in a narrow dike with a maximum width of 5.5 metres and
exposed for 52 metres in an area with poor outcrop. At the western end, the dike bifurcates, forming a
discordant southwest-trending arm. It is predominantly concordant with the foliation of the host
metasediments, which consist mainly of muscovite biotite pelites and minor metawackes that have
undergone medium-grade regional metamorphism. The dominant facies within the dike is the aplitic
facies, constituting approximately 80 percent of its composition. It consists of subhedral to anhedral
quartz phenocrysts embedded in a matrix of felty, white to pink cleavelandite. Other accessory minerals
include purpurite, beryl, muscovite, and apatite.
Both the aplite and pegmatite exhibit similar mineralogy on a macroscopic scale. However, the
pegmatite tends to have a higher modal percentage and coarser crystals of muscovite, purpurite, and
apatite. The highest concentration of beryl is found in the pegmatite, with observed crystal diameters
reaching up to 7.5 centimeters. Additionally, pod-like masses enriched in coarse-grained tourmaline
sporadically occur in the host metapelites along the northern contact between tourmaline-free sediments
and the pegmatite.
Planned Exploration Program
The Company is currently evaluating a potential exploration program including a broad MMI sampling
grid and UAV airborne magnetics.
The survey areas will be focused in and around the historical
pegmatite showing, as well as along the extensive contact zone of the greenstone metasediments and
the granitic batholith.
