Broadway Update on Madison Copper-Gold Porphyry Discovery, Phase III Drilling
06 3월 2018 - 11:00PM
Broadway Gold Mining Ltd. (TSX-V:BRD) (OTCQB:BDWYF) (“Broadway” or
the “Company”) is pleased to provide an update on its Phase III
surface drilling program at the Company’s 100%-owned Madison
copper-gold project in the historic Butte-Anaconda mining region of
Montana, USA.
Recently, Broadway has documented a
well-mineralized, two-mile-long geological, geophysical and
geochemical trend at Madison. Key highlights to date include:
- Confirmed new porphyry discovery in regional trend near Butte
region;
- Latite porphyry intercepted in holes C17-24 and C17-27;
- Porphyry body appears to be of significant size with intercepts
to date measuring up to 234 meters and open in all directions;
- Anomalous gold, silver, manganese, lead, sulfur, strontium and
zinc identified in the phyllically altered latite; and
- Geochemical analysis indicating characteristics consistent with
gold or gold-coper-rich systems.
"Our discovery of the quartz latite porphyry in
C17-24 pointed to a potential deep source for the broad zone of
skarn-jasperoid mineralization delineated near surface in our
previous drilling,” said Duane Parnham, President and CEO of
Broadway. “The presence of anomalous gold and copper grades, the
length of the porphyry intercepts and Whole Rock Analysis of the
core from Phase III drilling now support our belief that Madison is
capable of hosting a large hydrothermal system and concentrating
sufficient gold, copper and sulphur to form a significant
deposit.”
Based on Whole Rock Analysis interpretation
performed by Rex McLachlin, Consulting Senior Geologist for Childs
Geoscience, analysis of local intrusive rocks encountered in the
Phase III drilling show compositions consistent with a gold-rich or
gold-copper-rich productive magmatic-hydrothermal system.
Noteworthy attributes include evidence of high-pressure
fractionation of hornblende from a hydrous, calc-alkaline magma.
Such magma is capable of forming both large hydrothermal systems as
well as concentrating sufficient gold, copper, sulphur and water to
form a deposit.
Mr. McLachlin notes, “The latite porphyry at
Madison has low Y and Zr levels and high Nb, Th and Ba levels
indicating the system is highly prospective for copper and
particularly gold. Gold-productive magmas have higher than average
Nb/Zr ratios in 98% of cases and higher Th/Zr ratios in 80% of
cases. The geology at Madison is well above average for both of
these ratios. Similarly, Madison exhibits significantly lower Zr
levels than comparable barren calc-alkaline suites, which is
typical of known copper, copper-gold and gold porphyry
deposits.”

Seven holes totaling 2,323 meters have now been
drilled to complete Phase III as Broadway aggressively and
systematically tests IP targets highlighted during the
property-wide survey completed in 2017.
Final drilling assay results have been reported
for C17-27 with results confirming the presence of anomalous gold,
silver, manganese, lead and zinc. The anomalies are found in
sections of core exhibiting weak phyllic alteration halos around
quartz-calcite-pyrite micro-veinlets where enriched metal grades
exist relative to the background values found in the propylitically
altered latite as shown in Table 1.

Broadway is currently planning a follow-up
program to define the core of the porphyry system through
ground-based geophysical surveys, geologic mapping, soil and rock
chip sampling and drilling. The Company also intends to re-focus on
adding to the underground high-grade copper-gold skarn resource in
and around the historic Madison Mine.

About Broadway Gold Mining Ltd.
Broadway Gold Mining Ltd. is a resource company
focused on development-stage projects with advanced exploration
potential. The company owns a 100% interest in the Madison
copper-gold project located in the Butte-Anaconda mining region of
Montana, USA. The Madison project is permitted for exploration and
contains a past-producing underground mine that Broadway has
refurbished. While actively expanding known copper and gold zones
that remain open for development in the mine's perimeter, the
company's exploration program has identified new anomalies across
its extensive land package that provide compelling drill targets
that are believed to be associated with large-scale porphyry
mineralization.
