New Independent Study Points to Porphyry Potential at Lawyers
New Independent Study Points to Porphyry Potential at
Lawyers
Edmonton, Alberta--(Newsfile Corp. - December 6, 2019) -
Benchmark Metals Inc.
(TSXV: BNCH) (OTCQB: CYRTF) (WKN:
A2JM2X) (the "
Company
" or "
Benchmark
") Benchmark is pleased to share the results of a new independent study by the
'Mineral Deposit Research Unit' (MDRU) at the University of British Columbia and Geoscience BC. The study developed an
exploration framework for transitions of porphyry to epithermal deposits in the Toodoggone mineral district and focused on
several zones within the Lawyers project. This allows for improved targeted exploration and provides regional context for the
mineralized zones on the Lawyers property within the broader Toodoggone mineral district. The Lawyers Project is situated in
the Stikine Terrane of northern British Columbia, Canada, and falls within the prolific, mineral endowed 'Golden Horseshoe'.
John Williamson, CEO commented, "It is satisfying to see that MDRU and Geoscience BC have recognized the mineral
potential of the relatively underexplored Toodoggone mineral district and have provided this valuable exploration framework and
data set to industry. We are very encouraged by their observations of the potential link to a deeper porphyry system at Cliff
Creek. We look forward to reporting the 25 remaining drill holes from Cliff Creek and the additional 17 holes from the other
zones with much anticipation".
Regional Context - Toodoggone District
A British Columbia Geological Survey (BCGS) regional mapping program during the early 1990's spanned much of the
Toodoggone District, including the Lawyers property, but little subsequent regional studies and interpretation has followed. The
Toodoggone district is one of very few regions in BC where Early Jurassic epithermal mineralization is well-preserved. The
deposits and showings in the central and northern regions of the Toodoggone are classified as epithermal gold-silver deposits
(Duuring et al., 2009a), while in the southern region, numerous Late Triassic porphyry-type deposits occur, such as Kemess.
Variable degrees of erosion in the region contribute to the good exposure and preservation of both porphyry and epithermal
deposits.
MDRU & Geoscience BC Study and New Developments
New work by the Mineral Deposits Research Group (MDRU) at the University of British Columbia is shedding light on the
relationships between the porphyry and epithermal mineralization of the Toodoggone (
link to report
) that suggests historically
mined and explored epithermal deposits are part of larger porphyry systems. This is based on a new exploration framework that
uses a range of criteria including; field observations, alteration assemblages, vein types, trace metal concentrations, fluid
inclusion analysis, age dating, and a newly developed geochemical index (MPIx) for defining porphyry potential.
Using the above
criteria MDRU has determined several low-sulphidation epithermal systems have numerous features that are indicative of the
shallow parts of a porphyry system including the Cliff Creek zone on the Lawyers property (Figure 1).

Quality Assurance and Control
Results 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 (+10 g/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 they may not be
representative of the mineralization hosted on the project.
