ZincX Resources Provides Update on Metallurgical Test Work By Tongling

Rhea-AI Summary

ZincX Resources Corp. provides an update on metallurgical testing for the Cardiac Creek deposit. Ongoing tests, overseen by strategic partner Tongling Non-Ferrous Metals, aim to enhance recovery and concentrate grades of zinc and lead from drill core samples. The work includes waste disposal tests and flotation analysis. The 2021 diamond drill program yielded over 500 samples, with significant mineralization observed. The latest updates indicate a strong focus on improving the economic viability of the project, supported by robust results from a previous Preliminary Economic Assessment (PEA).

Positive

• Ongoing metallurgical testing expected to improve recovery rates and concentrate grades.
• Previous PEA indicates a robust economic outlook with a 35% pre-tax IRR and $649M NPV at 7% discount rate.
• Successful 2021 drill program recovered over 500 HQ drill core samples with significant mineralization.

Negative

• None.

VANCOUVER, BC / ACCESSWIRE / November 7, 2022 / ZincX Resources Corp. ("ZincX" or the "Company", TSX Venture Exchange:ZNX, OTCQB:ZNCXF, FRA:M9R) is pleased to provide an update on the detailed metallurgical test work that is underway on the Cardiac Creek drill core samples collected from the 2021 diamond drilling program. The samples were shipped to China in Q1 2022. The test work is being conducted at the Hunan Research Institute and the work is being overseen by the Company's strategic partner Tongling Non-Ferrous Metals of China (Tongling).

The Company has been informed by Tongling that the initial phase of the planned metallurgical test work is currently underway on the drill core. This includes waste disposal tests such as photoelectric waste disposal, centrifugal waste disposal and decarbonization via flotation. Additional test work of the material is ongoing. The Company is anticipating receiving additional information in the coming weeks.

The test work will include the following phases: (1) elimination of carbonaceous gangue on lead-zinc-silver flotation; (2) lead-zinc flotation test; (3) beneficiation wastewater treatment and reuse test; (4) mineral processing product inspection; (5) analysis of tailings dry heap storage method; and (6) mineral processing technology and economic evaluation.

Mr. Peeyush Varshney, President and CEO commented,

"We are delighted to be working with our strategic partner Tongling to further enhance both the metallurgical characteristics and economical potential of the deposit. We look forward to further updates from Tongling on the ongoing metallurgical test work that is being carried out on the drill core from the Cardiac Creek deposit."

The 2021 Drill Program

The Company completed a large-diameter HQ diamond drill program in 2021 consisting of five holes totalling 2,669 metres with an objective of acquiring mineralized drill core samples for advanced metallurgical testing. The drill holes targeted specific areas of the deposit along the northwest, down-dip, and southeast boundaries of the High-Grade core in order to provide samples that tests the variability of the deposit across its strike and width. All five holes successfully tested the Cardiac Creek Zone with excellent recovery of thick intervals of sphalerite-galena-barite mineralization. Greater than 500 HQ drill core samples were submitted and analyzed. A total of six individual metallurgical samples were selected, two from hole A-21-156B and one from each of the remaining drill holes. Individual samples averaged 228 kilograms and the total combined weight is in excess of 1350 kilograms. These samples will be used to continue to investigate the metallurgical response of the mineralization with a focus on enhancing recoveries and boosting concentrate grades for both zinc and lead.

The Akie Zn-Pb-Ag Project

The 100% owned Akie property is situated within the Kechika Trough, the southernmost area of the regionally extensive Paleozoic Selwyn Basin and one of the most prolific sedimentary basins in the world for the occurrence of SEDEX zinc-lead-silver and stratiform barite deposits.

Drilling on the Akie property by ZincX Resources since 2005 has identified a significant body of baritic-zinc-lead SEDEX mineralization known as the Cardiac Creek deposit. The deposit is hosted by siliceous, carbonaceous, fine-grained clastic rocks of the Middle to Late Devonian Gunsteel Formation.

The Company updated the estimate of mineral resources at Cardiac Creek in 2018, as follows:

5% Zinc Cut-Off Grade					Contained Metal:
Category	Tonnes (million)	Zn (%)	Pb (%)	Ag (g/t)	Zn (B lbs)	Pb (B lbs)	Ag (M oz)
Indicated	22.7	8.32	1.61	14.1	4.162	0.804	10.3
Inferred	7.5	7.04	1.24	12.0	1.169	0.205	2.9

The Company announced robust positive results from the 2018 Preliminary Economic Assessment (PEA). The PEA envisages a conventional underground mine and concentrator operation with an average production rate of 4,000 tonnes per day. The mine will have an 18-year life with potential to extend the life-of-mine (LOM) through resource expansion at depth. Key parameters for the PEA are as follows:

Parameter	Base Case1
Tonnes Mined	25.8 Mt
Mined Head Grades	7.6% Zn; 1.5% Pb; 13.08 g/t Ag
Tonnes Milled	19.7 Mt
Milled Head Grades (after DMS2 upgrade)	10.0% Zn; 1.9% Pb; 17.17 g/t Ag
Total Payable Metal (LOM)	$3,960M3
Initial CAPEX	$302.3M including $45.7M contingency
LOM Total CAPEX	$617.9M including $58.5M contingency
All-in Total OPEX	$102.4 per tonne milled
Pre-Tax NPV7%	$649M
Pre-Tax IRR	35%
Pre-Tax Payback	2.6 years
After-Tax NPV7%	$401M
After-Tax IRR	27%
After-Tax Payback	3.2 years

1. The base case used metal prices are calculated from the 3-year trailing average coupled with two year forward projection of the average price; and are: US$1.21/lb for zinc, US$1.00/lb for lead and US$16.95 for silver. A CDN$/US$ exchange rate of 0.77 was used. The NPV discount rate is 7%. 2. DMS = dense media separation. 3. All dollar amounts expressed in Canadian dollars.

The PEA is considered preliminary in nature and includes mineral resources, including inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves. Mineral resources that are not mineral reserves have not yet demonstrated economic viability. Due to the uncertainty that may be attached to mineral resources, it cannot be assumed that all or any part of a mineral resource will be upgraded to mineral reserves. Therefore, there is no certainty that the results concluded in the PEA will be realized.

Kechika Regional Project

In addition to the Akie Project, the Company owns 100% of eight of eleven large, contiguous property blocks that comprise the Kechika Regional Project including the advanced Mt. Alcock prospect. The Kechika Regional Project also includes the Pie, Yuen and Cirque East properties which the Company maintains a significant 49% interest with partners Teck Resources Limited (TSX: TECK.B) and Korea Zinc Co. Ltd holding 51%. These properties collectively extend northwest from the Akie property for approximately 140 kilometres covering the highly prospective Gunsteel Formation shale; the main host rock for known SEDEX zinc-lead-silver deposits in the Kechika Trough of northeastern British Columbia. These projects are located approximately 260 kilometres north northwest of the town of Mackenzie, British Columbia, Canada.
