BANYAN GOLD CORP. (“Banyan” or the “Company”) is pleased to announce gold recovery results from detailed metallurgical test work completed as part of the 2017 Hyland Gold Project Main Zone exploration program.
Banyan engaged Kappes Cassiday & Associates of Reno, NV ('KCA') to conduct metallurgical bottle roll and column leach test work on samples collected from dedicated metallurgical diamond drill holes; HY17-073, HY17-074 as well as one bulk composite sample towards determination of gold leach recoveries that may be obtainable using heap leach methods. Average gold recoveries from the three column leach tests were 86% (full details below) on 12.5 milimetre crushed material; tests were conducted over a 58 day period. Importantly, the test work also demonstrated strong leaching kinetics with a range of 73-87% of the ultimate recovery occurring within the first week of leaching.
“The recoveries and leach kinetics from a course crush are highly encouraging and confirm the Hyland Main Zone could be exploited as an open pit, heap leach operation”, said Tara Christie, President and CEO. “These results represent the first ever advanced recovery test-work completed on the Main Zone and deeply validate a potential scenario for economic extraction of gold mineralization from this deposit as an open-pit, heap leach operation. This potential is further validated by the recently announced $505M financing by Victoria Gold Corp. to fully fund the Eagle Gold Mine to commercial production as Eagle is a northern, open-pit, heap leach deposit with attractive economics. ”
The results of the three 2017 metallurgical column leach tests are summarized below:
Gold (Au) Column Leach Tests
Avg. Head Assay
Extracted % Au after 58 Days
% Au Extracted Recovered after 7 days
HY-17-073M - Oxide
HY-17-074M - Oxide
Bulk - Oxide
The results of column leach tests are consistent with previously reported (News release January 8, 2018), 96-hour bottle roll tests on three composite oxide samples reported average gold recoveries of 83.3% on the three oxide samples at a P80 0.15mm crush size.
Based on the strength of these column leach tests, a more robust metallurgical program will be accelerated as part of a larger 2018 Hyland Gold Project exploration program.
Towards that end, the Company has initiated a 2018 mobilization program to preposition fuel, drilling consumables and related exploration equipment. This winter 2018 mobilization effectively begins the 2018 Main Zone and Hyland Property exploration and will allow for an efficient and cost effective targeted 2018 mineral exploration program.

Chain of custody
Three oxide samples from dedicated diamond drill holes HY17-073 and HY17-074 from the 2017 Hyland Gold Project exploration program were sent for metallurgical testing by Kappes Cassiday & Associates of Reno, NV ('KCA'). Drill core samples were collected and sealed in poly bags at Banyan’s core processing facilities at the Hyland Gold Project. All these samples were delivered by Banyan personnel or a dedicated expediter and shipped directly to KCA in Reno, NV.
