CORNISH METALS CONTINUES TO INTERSECT HIGH GRADE TIN, COPPER, SILVER AND ZINC AT UNITED DOWNS
Cornish Metals Inc. has released assay results from two diamond drill holes, UD21-006 and UD21-008, which are part of the continuing drill program at the United Downs copper-tin project, Cornwall, United Kingdom.

True thicknesses of the mineralized intercepts are estimated to range between 20 and 50 per cent of the drilled lengths. Further drilling is required to establish true thickness of the structures. (2) Copper equivalent was calculated using: copper price of $9,800/tonne, tin price of $37,000/t, zinc price of $3,400/t and silver price of $24/ounce.
Richard Williams, chief executive officer, stated: "These results continue to demonstrate the presence of multiple mineralized structures within the UD lode target area. The intercepts in the latest holes do not appear to be part of UD lode itself but represent new subparallel zones of mineralization, including some exceptionally high tin grades. This is the first time we have encountered high-grade zinc mineralization, which occurs as coarse black sphalerite, and also note the high silver grades associated with the copper-rich zones. Additional drilling is required to understand the geometry and scale of these zones.
"The continued discovery of new mineralization by the current drilling underscores the prospective and underexplored nature of the United Downs area for near-surface tin, copper, zinc and silver. The drill program continues and results will be reported as and when received."
Geology and mineralization
The geology at United Downs comprises metasediments (locally termed killas), which overlie an intrusive granite body. All the historic copper mines within the area (United mines and Consolidated mines) and the historic tin, copper and zinc mines (Mount Wellington and Wheal Jane) exploited mineralization hosted entirely within killas.
The mineralization is primarily hosted in narrow, steeply dipping vein or lode structures, and consists of cassiterite (tin), chalcopyrite (copper) and sphalerite (zinc) with other copper minerals such as chalcocite and bornite occasionally present.
United mines and Consolidated mines, located 200 m south and 400 m north of UD lode, respectively, operated between the early 1700s and the 1870s, mining high-grade copper ores (reported grades of 7.5 per cent copper) to depths of up to 500 m below surface.
Mount Wellington and Wheal Jane mines exploited similar structures located along strike from the historic mining at United Downs, where tin, copper and zinc mineralization was mined and processed until 1978 and 1991, respectively. Wheal Jane was mined to a depth of approximately 500 m below surface whereas Mount Wellington only reached approximately 200 m depth before closing. Mount Wellington is located within Cornish Metals' mineral rights and was still in mineralization when the mined closed.
Technical information
Drilling at United Downs is being performed by Priority Drilling Company Ltd. using an Epiroc Christensen CT14 diamond drill rig. Mineralized zones were drilled in NQ (76-millimetre diameter) to recover a 48 mm diameter drill core. Core recovery was greater than 95 per cent. The core was logged, split and sampled by Cornish Metals personnel. The samples, comprising half core, were sent for assay to ALS, Loughrea, Ireland. Sample preparation involved crushing to 70 per cent less than two mm, riffle split and pulverized to 85 per cent less than 75 microns. The analytical method used was X-ray fluorescence (XRF) following a lithium borate fusion. Samples were assayed for with this technique include copper, tin, tungsten, zinc and arsenic. A multielement four-acid digestion ICP-AES (inductively coupled plasma atomic emission spectroscopy) analysis was also carried out to further characterize the mineralization and alteration assemblages. Overlimit assays on Ag were carried out using a three-acid digest and a hydrochloric acid leach ICP-AES analysis. A comprehensive quality assurance/quality control program using standards, duplicates and blanks was included within the sampling program.

Mr. Mihalop (MCSM, BSc (honours), MSc, FGS, MIMMM, CEng) is chief operating officer for Cornish Metals and has sufficient experience relevant to the style of mineralization and type of deposit under consideration and to the activity that he is undertaking to qualify as a competent person as defined under the JORC (Joint Ore Reserves Committee) code (2012) and as a qualified person under National Instrument 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.
