Vancouver, British Columbia, Canada – Tuesday, April 27, 2021 – ZincX Resources Corp. (“ZincX” or the “Company”, TSX Venture Exchange: ZNX, US: ZNCXF, FRA: A2JLRM ) is pleased to provide additional detail about the previously announced 2021 Akie Drill Program totaling approximately 2,000 metres scheduled to begin in late May to early June.
2021 Drilling Program
The 2021 drill program will consist of three holes totalling approximately 2,000 metres of drilling with a primary objective of acquiring mineralized drill core samples for advanced metallurgical testing. The holes will target specific areas of the deposit to provide variability of the deposit across its strike and width. This material will be used to further investigate the metallurgical response of the mineralization with a focus on enhancing the recoveries and boosting concentrate grades for both zinc and lead; using state-of-the-art metallurgical testing facility owned by Tongling Non-Ferrous Metals of China (Tongling).
The three drill holes will target the Cardiac Creek deposit’s high-grade core focused on the northwest, central and southeast areas. The specific targets have been selected to achieve two objectives; the Company’s primary objective of acquiring additional material for metallurgical testing; and provide valuable infill information to be used in future assessments of the deposit.
The first of the three planned drill holes will target the northwest area of the high-grade core proximal to historical drill holes A-07-51, A-13-107, and A-17-132. These three historical holes all yielded high-grade results including 23.42 metres (TW) of 12.40% Zn+Pb and 15.1g/t Ag in hole A-07-51; and 28.67 metres (TW) of 10.38% Zn+Pb and 14.2g/t Ag in hole A-17-132. The hole is currently planned for a total depth of 640 metres.
The second planned drill holes will target the central area of the high-grade core in the vicinity of A-06-35, A-17-127 and down-dip of A-05-30. The central area has yielded some very high-grade results including 25.06 metres (TW) of 14.70% Zn+Pb and 23.98g/t Ag in A-05-30, and 12.97 metres (TW) of 10.71% Zn+Pb, and 16.03g/t Ag in A-06-35. Information obtained from the second of three holes will yield valuable information from this area which has produced some of the highest grades encountered in the deposit. The hole is planned for a total depth of 740 metres.
The final planned hole will target the southeast area of the high-grade core surrounded by A-05-33, A-06-40, and A-13-105. Recent drill results include 13.77 metres (TW) of 10.54% Zn+Pb and 16.01g/t Ag in A-05-33, and 10.36 metres (TW) of 8.52% Zn+Pb and 11.55g/t Ag in A-06-40. This drill hole is planned for a depth of 475 metres.
Additional drill targets and/or exploration activity will be contemplated as budget and time constraints allow.
2018 Metallurgical Testing
The Company previously announced metallurgical test results in conjunction with the Cardiac Creek PEA. At the time, the Company fully expected metallurgical testing to be an iterative process and this year’s work will continue to seek improvements to bolster the significant value of the Cardiac Creek deposit. The inherent value of the Cardiac Creek deposit is largely driven by the zinc, as the contained zinc to lead ratio of the deposit is greater than 5 to 1. It is anticipated that additional work by Tongling at their state-of-the art test facility in Tongling, China, will enhance recovery and grade, particularly with respect to improvements in lead recovery and consequent silver recovery.
Results from locked cycle testing with a primary grind size of 56µm K80 and lead and zinc regrind sizes of 10 and 14µm K80, respectively, showed:
- Flotation testing on the global composite indicated that a conventional reagent scheme produced clean, marketable concentrates
- Zinc Concentrate: Zinc was 89% recovered into a concentrate grading 52.4%
- Lead Concentrate: Lead was 46% recovered into a concentrate grading 45%
- Saleable concentrates can be produced for both Zn and Pb
- No potential impurity or penalty elements were identified in the concentrates
- Dense Media Separation (DMS) separation was very efficient at rejecting barren gangue and improving recovery of lead and zinc; average global composite rejection was 25% of the feed mass
This work clearly demonstrated using DMS and conventional milling and floatation techniques can produce clean, saleable concentrates for both zinc and lead with no penalty elements. The tests were performed by Base Metallurgical Laboratories Ltd of Kamloops, British Columbia, under the supervision of principal metallurgist Tom Shouldice, P.Eng. Assistance and program design was provided by Kelly McLeod, P.Eng. of JDS Energy and Mining Inc. of Vancouver, BC.
