TORONTO, March 20, 2023 /CNW/ - Excellon Resources Inc. (TSX: EXN) (OTCQB: EXNRF) (FRA: E4X2) ("Excellon" or the "Company") is pleased to announce the initial diamond drilling results from the recently completed 2022-2023 exploration program at its Oakley property in Idaho, USA ("Oakley"). Assays from additional six drill holes are still outstanding.
Centerra (U.S.) Inc. ("Centerra"), a wholly owned subsidiary of Centerra Gold Inc. (TSX:CG and NYSE:CGAU), has an option to earn up to a 70% interest in Oakley by, among other things, spending US$7 million in exploration expenditures on the project by May 2026. At the end of February 2023, Centerra had spent US$4.5 million to earn an initial 51% interest in Oakley.
Highlights
"These intercepts extend mineralization by more than 120 metres (m) from the nearest drill hole and represent a significant step towards unlocking the potential of the Blue Hill Creek claims," stated Jorge Ortega, Vice President Exploration at Excellon. "We are encouraged by these initial results as they demonstrate that the deposit is open to the south and the west, and confirm the outstanding opportunity to increase the currently defined inferred mineral resource estimate (163,000 oz Au; 9,972,000 tonnes (t) @ an average grade of 0.5 g/t Au)1".

Drilling at Cold Creek focused on testing mineralization within the Tertiary Conglomerate unit that hosts mineralization at Oakley to the south of the currently defined mineralization footprint. Although weakly mineralized conglomerates were encountered, no significant Au values were reported. At Blue Hill Creek, the assay results for three diamond drill holes have been received. BHC-22-01 tested the location of the mineralization-bounding Tertiary Conglomerate/Paleozoic Limestone contact and did not intersect significant mineralization. Both BHC-22-02 and BHC-22-03 intersected wide mineralized zones east of the previously identified mineralization, indicating that the Tertiary Conglomerate unit extends 100 metres deeper than anticipated, which significantly increases the potential of the area to host mineralization.

The drill results contained in this news release have been prepared in accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101") of the Canadian Securities Administrators ("CSA"). True widths of cited intercepts are unknown.
Oakley drill core samples are prepared and assayed by Bureau Veritas lab ("BV") at Elko, Nevada. BV is accredited to ISO/IEC 17025:2017. Assay turnaround times have been impacted recently by a worldwide increase in demand for laboratory services. Centerra has a comprehensive quality assurance and quality control ("QA/QC") program supervised by a Qualified Person, as defined in NI 43-101.
The sampling of, and assay data from, the core sampling and reporting are monitored through a QA/QC program designed according to best industry practices. Samples from HQ drill core are selected by Centerra geologists and cut into halves at the project site. Half of the core is retained at the site for reference purposes. Samples are labelled and packed into sealed plastic bags which are grouped into larger fibre bags for shipping. A formal chain-of-custody procedure is in place for the security of samples from project to laboratory.
Samples are shipped by Centerra staff to the BV laboratory in Elko, Nevada. Samples then undergo crushing to 70% passing 10 US Mesh (2mm), rotary split of 250 grams, a 50-gram sub-sample is selected for analysis. Fire assay with atomic absorption spectrometry for gold is performed at Reno, Nevada BV facility, and ICP-MS 36 multi-element analysis is performed at Vancouver, British Columbia BV laboratory.
Mr. Jorge Ortega, P. Geo, Vice President Exploration of the Company and a Qualified Person, as defined in NI43-101, reviewed, verified and approved the scientific and technical information contained in this news release.
The Oakley Project is a gold-silver exploration prospect located 21 km south of Oakley, Idaho. The Oakley project totals 2,833 hectares. The exploration targets include hot-spring style low-sulfidation epithermal mineralization hosted by tertiary rocks as well as the potential for low-sulfidation Carlin-style epithermal mineralization hosted within Basin-and-Range Palaeozoic sediments. The property lies along the western flank of the Albion Mountains, part of the Albion-Raft River-Grouse Creek Metamorphic Core Complex. Oakley contains multiple targets, including Cold Creek, Blue Hill Creek and Matrix Creek. The Oakley Project's mineralization at Blue Hill Creek is comparable to Liberty Gold's Black Pine project, also in southern Idaho, currently with an indicated mineral resource estimate of 2.613 M Au oz (157,267,000 t @ an average grade of 0.52 g/t Au and inferred mineral resource estimate of 0.48 M Au oz (35,150,000 t @ an average grade of 0.43 g/t Au). The Black Pine mineral resource estimate was reported using a constraining resource pit at a cut-off grade of 0.20 g/t Au. As reported by Libery Gold, metallurgical testing at Black Pine is positive, averaging an 80.8% gold recovery for oxidized ore on column leach tests.2

Until mineral deposits are actually mined and processed, mineral resources must be considered as estimates only. Mineral resource estimates that are not classified as mineral reserves do not have demonstrated economic viability. The estimation of mineral resources is inherently uncertain, involves subjective judgement about many relevant factors and may be materially affected by, among other things, environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant risks, uncertainties, contingencies and other factors described in the foregoing Cautionary Statements. The quantity and grade of reported "inferred" mineral resource estimates are uncertain in nature and there has been insufficient exploration to define "inferred" mineral resource estimates as an "indicated" or "measured" mineral resource and it is uncertain if further exploration will result in upgrading "inferred" mineral resource estimates to an "indicated" or "measured" mineral resource category. The accuracy of any mineral resource estimates is a function of the quantity and quality of available data, and of the assumptions made and judgments used in engineering and geological interpretation, which may prove to be unreliable and depend, to a certain extent, upon the analysis of drilling results and statistical inferences that may ultimately prove to be inaccurate. The quantity and grade of "inferred" mineral resource estimates are uncertain in nature and there has been insufficient exploration to define "inferred" mineral resource estimates as an "indicated" or "measured" mineral resource and it is uncertain if further exploration will result in upgrading "inferred" mineral resource estimates to an "indicated" or "measured" mineral resource category. Mineral resource estimates may have to be re-estimated based on, among other things: (i) fluctuations in mineral prices; (ii) results of drilling and development; (iii) results of geological and structural modeling including stope design; (iv) metallurgical testing and other testing; (v) proposed mining operations including dilution; and (vi) the possible failure to receive and/or maintain required permits, licenses and other approvals. It cannot be assumed that all or any part of a "inferred", "indicated" or "measured" mineral resource estimate will ever be upgraded to a higher category including a mineral reserve.
The mineral resource estimates declared by the Company were estimated, categorized and reported using standards and definitions using Canadian Institute of Mining, Metallurgy and Petroleum Definition Standards for Mineral Resources and Mineral Reserves (the "CIM Standards") in accordance with NI 43-101 of the CSA, which governs the public disclosure of scientific and technical information concerning mineral projects by Canadian issuers such as Excellon.
The terms "mineral resource", "measured mineral resource", "indicated mineral resource" and "inferred mineral resource" as disclosed by the Company are Canadian mining terms defined in the CIM Standards (collectively, the "CIM Definitions") in accordance with NI 43-101. NI 43-101 establishes standards for all public disclosure that a Canadian issuer makes of scientific and technical information concerning mineral projects. These Canadian standards differ from the requirements of the United States Securities and Exchange Commission (the "SEC") applicable to United States domestic and certain foreign reporting companies under Subpart 1300 of Regulation S-K ("S-K 1300"). Accordingly, information describing mineral resource estimates for the Company's projects, including Oakley, may not be comparable to similar information publicly reported in accordance with the applicable requirements of the SEC, and so there can be no assurance that any mineral resource estimate for the Company's projects would be the same had the estimates been prepared per the SEC's reporting and disclosure requirements under applicable United States federal securities laws, and the rules and regulations thereunder, including S-K 1300. Further, there is no assurance that any mineral resource or mineral reserve estimate that the Company may report under NI 43-101 would be the same had the Company prepared such estimates under S-K 1300.
Information regarding the Black Pine project in this news release was obtained from the noted third party source. The accuracy and completeness of such third-party project disclosure is not guaranteed and Excellon makes no representation as to the accuracy of such data. The Company accepts no responsibility for referenced third-party sources and shall have no liability arising from, such sources.
