Broadway Discovers New Gold Zone at Madison and Expands Native Copper Zone

VANCOUVER, BC--(Marketwired - May 18, 2017) - Broadway Gold Mining Ltd. (TSX VENTURE: BRD) (OTCQB: BDWYF) (FRANKFURT: BGH) ("Broadway" or the "Company") is pleased to report additional assay results from the C17-08, C17-09 and C17-13 2017 from the Phase II surface drilling campaign at its 100%-owned Madison copper-gold project in the historic Butte-Anaconda mining region of Montana, USA.

Highlights of the results include:

• 1.466% Cu and 0.253 grams per tonne (g/t) Au over 20.1 meters in hole C17-13
  • Including 6.048% Cu and 0.357 g/t Au over 4.6 meters
  • Including 11.45% Cu and 0.020 g/t Au over 1.8 meters
• 1.882% Cu and 4.249 grams per tonne (g/t) Au over 3.7 meters in hole C17-09
• 0.760 g/t Au over 33.8 meters in hole C17-09
• 1.152 g/t Au over 2.7 meters in hole C17-08

"A new third deposit type, lower grade gold over longer widths within the skarn zone, has now been discovered in C17-09 west of the high-grade gold massive sulphides drilled underground," said Duane Parnham, President and CEO of Broadway Gold Mining. "We continue to confidently increase the strike length of the copper zone delivering more high grade hits. After a brief pause to analyze the drilling data, geophysical results and surface sampling, Broadway will continue with an extensive Phase III drilling program," added Mr. Parnham.

Assay Results Summary

The true thickness of the copper and gold zones have not yet been established

The complete assay results for the intervals and a drilling plan can be found on the current exploration page of the Company's website.

The surface drilling continues to expand the copper bearing jasperoid zone to the northwest, with the zone now traced 75 meters and open at both ends. The historic drilling completed through this area and along strike in both directions provided only rudimentary geological information with long intervals not previously assayed for copper. Broadway has already found significant new copper mineralization, increasing the possibility of further mineralization and open at depth.

The assaying has also identified a new type of mineralization at Madison, lower grade gold, within an epidote-diopside-garnet skarn zone, clearly evidenced in C17-09. The only noted mineralization within the auriferous horizon is pyrite, ranging from trace to locally 20%. Based on this new mineralization, the Company will review the historic database looking for similar mineralized zones.

The copper interval in C17-13 was contained within two jasperoid zones, 2.9 meters and 3.0 meters separated by a 7.2 marble interval. This interval also includes 7.0 meters of overlying polylithic breccia containing significant copper. The strongest copper mineralization was found in the upper jasperoid zone and consisted on abundant copper oxides.

The copper interval in C17-09 was centred on a 1.9 meter jasperoid containing 1% to 2% native copper. Native copper was also logged in the top 1.6 meters of the underlying hedenbergite-jasper skarn. The top 0.15 meters of the interval included epidote skarn.

A longer 33.8 meter and a shorter 11.0 meter interval of epidote-diopside-garnet skarn carrying interesting gold values, was also intersected in C17-09. The two zones appear to carry pyrite in concentration ranging from trace to 20%, largely as clots and blebs. Interestingly, there does not appear to be a relationship between the more auriferous sections and the percentage of sulfides. This is a style of mineralization previously unknown at Madison.

The gold interval in C17-08 was contained largely within an epidote breccia containing 1% to 7% pyrite.

All analyses were completed at the ALS Minerals Laboratory in North Vancouver, British Columbia, an ISO/IEC 17025:2005 certified facility. Broadway is utilizing a program of third-party standards and blanks inserted at regular intervals through the sample stream as its QA/QC program. AK Drilling, Inc. of Butte, Montana is the contractor performing the surface drilling programs.

Sample Preparation and Quality Control

Supervision, organization and splitting of drilling core samples were undertaken by company personnel. Samples were collected at three-foot intervals from half core samples. Samples were catalogued by Broadway geologists and stored in a secure location. Certified reference standards were placed in the sample stream of each drill hole at random intervals. Blank material was also inserted at random intervals. Samples were packed into rice bags, zap strapped and securely stored until they were turned over to the local trucking company for transport to the ALS Minerals Laboratory in North Vancouver, B.C.

Laboratory Quality Assurance/Quality Control

Quality control samples from the lab include numerous control blanks, duplicates and standards. Reference standards used include OREAS-904, OREAS-45b, OGGeo08 and PGMS25. No issues were noted with analytical accuracy or precision.

Assay Techniques

Three different assay procedures were designed by ALS Minerals for the samples, based on the presence of copper sulfides or oxides, and native copper. The standard assay procedure of Au-ICP21 and Cu-ICP61 was applied to most of the samples. Au-ICP21 is a 30 gram fire assay with an ICP-AES finish. ICP61 is a four acid digestion of a one gram sample with an ICP finish. Samples with visible copper mineralization received a Cu-OG62 copper analysis, a four acid digestion of a 0.5 grams sample with ICP-AES finish. OG62 has a copper range from 0.001 to 40%, while the ICP61 analysis has a copper maximum range of 10,000 ppm. Samples with visible native copper received a duplicate Cu-OG62 analysis that included a WSH-22 procedure where the pulverizers are cleaned with barren material after every sample. Over-limit copper values from the ICP61 analyses received an OG62 procedure to determine the final Cu grade.

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.
