Cornish Metals Releases Assay Results for No. 4, No. 8 and Roskear B Lodes as Part of the South Crofty Tin Project Metallurgical Drill Programme

VANCOUVER, British Columbia, July 04, 2023 (GLOBE NEWSWIRE) — Cornish Metals Inc. (TSX-V/AIM: CUSN) (“Cornish Metals” or the “Company”), a mineral exploration and development company focused on its South Crofty tin project in Cornwall, United Kingdom, is pleased to announce assay results from the recently completed metallurgical drill programme at South Crofty Tin Project, Cornwall, UK.

Richard Williams, CEO of the Company stated: “On a global perspective these are high grade tin assay results, but they reflect typical widths and grades of the tin mineralisation we have encountered and mined historically at South Crofty and serve to confirm and add further confidence to the Mineral Resource estimate we have for the No. 4, No. 8, and Roskear B Lodes. We look forward to receiving the results from the metallurgical studies for these areas, including diluted head grades, ore sorting amenability, gravity release and paste backfill studies, which are expected by the end of Q3, 2023.”

The assays results for this drilling are presented below and can be viewed in the long sections of No. 4, No. 8 and Roskear B Lodes through the links.

The metallurgical drill programme comprised fourteen parent and daughter drill holes targeting No. 4 and No. 8 Lodes, and fourteen parent and daughter holes targeting the Roskear Lode. Visible tin mineralisation was observed in all 28 drill holes. Three holes from each Lode were assayed for tin and the rest of the full drill intercepts were used for metallurgical studies.

Drilling has also now been completed into the North Pool Zone and the Dolcoath lodes with four parent and 29 daughter holes respectively. Assay and metallurgical results from these holes will be released when received.

ABOUT CORNISH METALS

Cornish Metals is a dual-listed company (AIM and TSX-V : CUSN) focused on advancing the South Crofty high-grade, underground tin project through to delivery of a Feasibility Study, as well as exploring its additional mineral rights, all located in Cornwall, South West England. The former producing South Crofty tin mine is located beneath the towns of Pool and Camborne, and closed in 1998 following over 400 years of continuous production. Since acquiring the project in 2016, Cornish Metals has completed and published maiden NI 43-101 Mineral Resources for South Crofty using the vast archive of historical production data and more recent drilling completed between 2007 and 2013. Additionally, Cornish Metals has undertaken extensive pilot-scale water treatment trials and successfully applied for and received the necessary environmental permits to abstract, treat and discharge mine water in order to dewater the mine. Planning permissions for the operation of the mine and re-development of the surface facilities have been secured and construction of the water treatment plant is currently well underway.

An updated Mineral Resource was completed in June 2021 as summarised below:

South Crofty Summary (JORC 2012) Mineral Resource Estimate
Area Classification Mass (‘000 tonnes) Grade Contained Tin / Tin Equivalent (‘000 tonnes) Increase in contained Tin / Tin equivalent from 2016 MRE
Lower Mine Indicated 2,084 1.59% Sn 33 10.2%
Inferred 1,937 1.67% Sn 32 129.8%
 
Upper Mine Indicated 277 1.01% SnEq 3 9.5%
Inferred 493 0.93% SnEq 5 8.0%

The Mineral Resource Estimate for South Crofty (see news release dated June 9, 2021), is available in a report titled the “South Crofty Tin Project Mineral Resource Update”, dated June 7, 2021, authored by Mr. N. Szebor, CGeol (London), EuroGeol, FGS, of AMC Consultants (UK) Ltd, can be accessed on the Company’s SEDAR page.

TECHNICAL INFORMATION

Drilling at South Crofty was performed by Priority Drilling Company Ltd using an Atlas Copco CS14 Surface Diamond Drill Rig and an Atlas Copco U6 deep hole underground Diamond Drill Rig. The mineralised zones were drilled in NQ (76 mm diameter) to recover a 48mm diameter drill core. Core recovery was greater than 95%. The core was logged, split via core saw, and sampled by Cornish Metals personnel. The samples, comprising quarter core, were sent for assay at ALS Minerals, Loughrea, Ireland. Sample preparation involved crushing to 70% less than 2mm, riffle split and pulverised to 85% less than 75 microns. The analytical method used for copper, tin, tungsten, zinc and arsenic was X-ray florescence (XRF) following a lithium borate fusion. A multi-element 4 Acid Digestion ICP-AES analysis was also carried out to further characterise the mineralisation and alteration assemblages. Comprehensive Quality Assurance / Quality Control programme using standards, duplicates and blanks was included within the sampling programme.

The technical information in this news release has been compiled by Mr. Owen Mihalop. Mr. Mihalop has reviewed and takes responsibility for the data and geological interpretation. Mr. Owen Mihalop (MCSM, BSc (Hons), MSc, FGS, MIMMM, CEng) is Chief Operating Officer for Cornish Metals Inc. and has sufficient experience relevant to the style of mineralisation and type of deposit under consideration and to the activity which he is undertaking to qualify as a Competent Person as defined under the JORC Code (2012) and as a Qualified Person under NI 43-101. Mr. Mihalop consents to the inclusion in this announcement of the matters based on his information in the form and context in which it appears.
