New Placer Dome Gold Corp. (TSX-V: NGLD) (OTCQB: NPDCF) (FSE: BM5) is pleased to report additional analytical results from five reverse circulation drill holes completed at the Company’s Bolo Gold-Silver Project. The second batch of holes intersected significant oxide gold and extended mineralization at depth in the South Mine Fault Zone, which remains open for expansion. The remaining four holes from the 2020 RC drill program are at ALS laboratories in North Vancouver awaiting prep and fire assays. The Bolo Gold-Silver Project is in a proven and prolific mining area within Nevada, USA.
The Bolo RC drill campaign, completed in November 2020, comprised 14 drill holes totaling 4,159 metres (13,645 feet). Seven of the ten holes for which assay results have been received to date have encountered significant oxide gold mineralization (Table 1). Laboratory assay results from four additional expansion drill holes are still pending.
The considerable length of the gold intercepts in BL20-06, and in BL20-05 above indicate that the mineralized structures hosting leachable gold in the South Mine Fault Zone have significant vertical and lateral extent. These results speak to the continuity and overall strength of the mineralized system at Bolo.
Hole BL20-10 intersected shallow oxide gold mineralization below 2019 drill hole BL19-07, which returned strong arsenic pathfinder values. A similar arsenic anomaly was encountered in BL20-10 coincident with the reported gold intercept. New Placer Dome’s technical team has established that pathfinder anomalies are a powerful vectoring tool to identify mineralized structures in the South Mine Fault Zone and elsewhere at the Bolo Gold-Silver Project.
Kris Raffle, P.Geo., and a director comments, “Our continued success in identifying oxide gold mineralization in the South Mine Fault Zone over multiple drill campaigns not only bolsters our understanding of the complex structural controls on mineralization at Bolo, but also presents the Company with a persuasive argument to explore other under-drilled or un-drilled areas of the Project with similar geological characteristics.”
|1 The true width of mineralization is estimated to be approximately 60-70% of drill width.|

RC drilling at Bolo defines a 1.2 kilometer north-south trending corridor of gold-silver mineralization containing the South Mine Fault Zone, Uncle Sam, and Northeast Extension zones. Gold mineralization at Bolo exhibits characteristics of classic Carlin-type mineralization, including strong subvertical structural control in addition to evidence of gold mineralization extending laterally at low angles within favorable silty carbonate units.

Methodology and QA/QC
The analytical work reported on herein was performed by ALS Global, Vancouver Canada. ALS is an ISO-IEC 17025:2017 and ISO 9001:2015 accredited geoanalytical laboratory and is independent of New Placer Dome and the QP. RC drill samples were subject to crushing at a minimum of 70% passing 2 mm, followed by pulverizing of a 250 gram split to 85% passing 75 microns. Gold determination was via standard atomic absorption spectroscopy finish 30 gram fire-assay analysis, in addition to 48 element ICP-MS geochemistry. For any samples assaying over 0.1 ppm gold an additional 30 gram cyanide leach analysis is completed whereby the sample is treated with a 0.25% NaCN solution and rolled for an hour. An aliquot of the final leach solution is then centrifuged and analyzed by AAS.
New Placer Dome follows industry standard procedures for the work carried out on the Bolo Gold-Silver Project, with a quality assurance/quality control program. Blank, duplicate and standard samples were inserted into the sample sequence sent to the laboratory for analysis. New Placer Dome detected no significant QA/QC issues during review of the data. New Placer Dome is not aware of any drilling, sampling, recovery or other factors that could materially affect the accuracy or reliability of the data referred to herein.
About New Placer Dome Gold Corp.
New Placer Dome Gold Corp. is a gold exploration company focused on acquiring and advancing gold projects in Nevada. New Placer Dome’s flagship Kinsley Mountain Gold Project, located 90 km south of the Long Canyon Mine (currently in production under the Newmont/Barrick Joint Venture), hosts Carlin-style gold mineralization, previous run of mine heap leach production, and NI 43-101 indicated resources containing 418,000 ounces of gold grading 2.63 g/t Au (4.95 million tonnes) and inferred resources containing 117,000 ounces of gold averaging 1.51 g/t Au (2.44 million tonnes)3. The Bolo Project, located 90 km northeast of Tonopah, Nevada, is another core asset, similarly hosting Carlin-style gold mineralization. New Placer Dome also owns 100% of the Troy Canyon Project, located 120 km south of Ely, Nevada. New Placer Dome is run by a strong management and technical team consisting of capital market and mining professionals with the goal of maximizing value for shareholders through new mineral discoveries, committed long-term partnerships, and the advancement of exploration projects in geopolitically favourable jurisdictions.
