Benchmark Metals Inc. (the
“
Company” or “
Benchmark”) (TSX-V:
BNCH) (OTCQB: CYRTD) (GER: A2JM2X) (FKT: A7CA) – is pleased to
report evidence for multiple stages of precious metal
mineralization at the Lawyers Gold & Silver Project, located in
the Golden Triangle region of British Columbia, Canada.
CEO John Williamson commented, “The Lawyers
Project presents a tremendous opportunity for the development of
near-surface or buried bulk tonnage deposit. After a comprehensive
exploration program, we are excited to have discovered evidence
suggesting the occurrence of multistage events of precious metal
mineralization that may explain the high-grade results from recent
rock grab samples. The geological team is seeing mineralization
that resembles a porphyry system.”.
Lawyers Geological PotentialThe
porphyritic andesite with potassic (k-feldespar + shreddy biotite)
overprinted by phyllic alteration (quartz + sericite + pyrite)
resembles porphyry-type disseminated bulk tonnage mineralization.
This type of mineralization typically yields lower gold-silver
grades (e.g. 0.525 grams per tonne Au, 15.4 g/t Ag over 2m; Figure
1.a) and is widely spread within the property.
The alteration mineral association of alunite
and dickite observed over 0.5km to 2km trends to the west of the
main mineral deposits (AGB, Cliff Creek, and Dukes Ridge),
indicating high sulfur fugacity characteristic of high-sulfidation
precious metal deposits, although no lithocaps, vuggy silica, or
high-sulfidation-state hypogenic sulfides such as covellite,
digenite, or enargite have been identified. This may suggest the
presence of a magmatic-hydrothermal system that includes
high-sulfidation precious-base metal deposits possibly linked to
deeper porphyry-type mineralization that may have been eroded and
structurally dislocated.
Furthermore, high Au-Ag grades (220g/t Au,
>10,000g/t Ag) have been observed related to electrum and silver
sulphosalts associated with calcite, adularia, and quartz with
crustiform and cockade textures. This mineral association and
textures are more characteristic of epithermal low-sulfidation
precious metal deposits and has been observed overprinting the
formerly described “porphyry-type” mineralization in the Phoenix
area, see Figure #1 below.

This evidence increases substantially the
economic potential of the Toodoggone district.
Benchmark has commenced academic studies,
including XRD analyses to verify alteration minerals identified in
the field with TerraSpec analyzers, ore petrography supported with
microprobe analyses to properly characterize the mineral
paragenesis, fluid inclusion microthermometry to identify
temperature and salinities of ore-forming fluids, as well as
geochemistry and geochronology of both alteration minerals and
associated magmatic rocks.
The overall objective of these academic studies
is to gain a better understanding of the ore-forming processes at
both district and regional scales that would enable us to conduct
exploration more efficiently.
The Lawyers Project sits within the Toodoggone
district, which also contains the Shasta, Baker, Bonanza, and the
world-class Kemess and Kemess North copper gold deposits, and
numerous other gold-silver-copper prospects are in various stages
of exploration and development. Clark and Williams (1990) described
a range of deposits from gold-rich porphyry-style deposits, to
deep-seated precious and base metal bearing stockworks and veins,
to near-surface replacement-type gold mineralization. The most
economically significant deposits exhibit characteristics typical
of epithermal alteration and mineralization of both
adularia-sericite and acid sulphate affinities (Clark and Williams,
1990).
Age dating of the adularia-sericite alteration
around the mineralisation at the Lawyers (AGB and Cliff Creek) and
Shasta deposits suggest that they formed between 187-190 Ma (Clark
and Williams-Jones, 1990). The timing of mineralisation, as well as
rocks which host the Lawyers mineralisation (Toodoggone Volcanics),
overlaps with the age and emplacement of several well known
porphyry and epithermal deposits in northwest British Columbia
(including Kerr-Sulphurets-Mitchell, Snowfield, and Brucejack
(Febbo, 2016; Tombe et al. 2018)). This timing marks a shift in the
volcanic arc-development resulting in a metallogenic epoch hosting
many significant deposits in the Stikinia Terrane.
The work to be conducted by Benchmark will help
to elucidate the relationship between such a range of
mineralization styles within the district.
2018 Exploration ProgramDuring
the current field season, Benchmark collected 1,041 soils samples
covering 29 line kilometers and over 7.2 km2. Several areas of
anomalous gold have been identified on the soil grids, as well as
localized geochemical anomalies in As, K and Zn. Mapping and
prospecting was conducted and a total of 312 rock samples were
collected across the property. An airborne geophysical survey was
also conducted over the property at 100 meter line spacing.
Benchmark completed a total of 4,116 meters of drilling, including
1,493 meters of diamond core drilling and 2,623 meters of reverse
circulation drilling at the Dukes Ridge, Cliff Creek and Phoenix
Zones. Several intersections of veining, brecciation and
fine-grained sulfosalts were observed in the drilling, occurring in
areas with little existing drill hole data.
Lawyers Gold and Silver
ProjectThe Lawyers Property and formerly producing Cheni
Gold and Silver Mine is located 45 km northwest of the Kemess Gold
and Copper Mine. The Property contains an existing Mineral Resource
hosts a minimum of 16 existing gold and silver occurrences that
were never fully mined, developed or explored. Work during the 2018
exploration program has focused on mineralized zones with exposure
at surface. Each zone remains open at strike, width and
depth, extending across hundreds of meters. The 99km2
prospective land package presents a unique opportunity for
Benchmark to carry out exploration on a ‘camp’ scale. There remains
excellent potential for the discovery of additional low and
high-sulphidation epithermal precious metal deposits like those
that have been discovered and explored to date in the Golden
Triangle region. In addition, there exists the possibility
for the discovery of near-surface or buried ‘bulk tonnage’ deposits
which may offer the advantage of economies of scale should future
mine development occur.
Quality Assurance and
ControlResults from samples were analyzed at ALS Global
Laboratories (Geochemistry Division) in Vancouver, Canada (an ISO
9001:2008 accredited facility). The sampling program was undertaken
by Company personnel under the direction of Rob L’Heureux, P.Geol.
A secure chain of custody is maintained in transporting and storing
of all samples. Gold was assayed using a fire assay with atomic
emission spectrometry and gravimetric finish when required (+10g/t
Au). Analysis by four acid digestion with 48 element ICP-MS
analysis was conducted on all samples, with silver and base metal
overlimits re-analyzed by atomic absorption or emission
spectrometry. Rock chip samples from outcrop/bedrock are selective
by nature and may not be representative of the mineralization
hosted on the project.
