Reported the second set of assays from the diamond drilling programme conducted by Cornish Lithium at the United Downs project earlier in 2020.

Highlights included multiple zones of copper and / or tin mineralisation have been intersected, and mineralisation extends over at least 750 metres (“m”) vertical extent and is open along strike and to depth.

Cornish Metals Reports Multiple Copper and Tin Drill Intersects From United Downs Including 4.04 metres grading 4.44% Copper and 2.06% Tin

VANCOUVER, British Columbia, Nov. 18, 2020 – Cornish Metals Inc. (TSX.V: CUSN) (“Cornish Metals” or the “Company”) is pleased to report the second set of assays from the diamond drilling programme conducted by Cornish Lithium at the United Downs project earlier in 2020.

HIGHLIGHTS

  • Multiple zones of copper and / or tin mineralisation have been intersected
  • Mineralisation extends over at least 750 metres (“m”) vertical extent and is open along strike and to depth
  • Identification of at least five new zones of copper and / or tin mineralisation
  • The two drill holes reported here were drilled to test for lithium in brines, yet discovered new zones of copper / tin mineralisation highlighting the regional potential for new discoveries
  • All mineralised zones are tabulated below:

Richard Williams, CEO, stated “These results add further confidence to the exploration potential at United Downs between and beneath the former copper producing United Mines and Great Consolidated Mines. This drilling has identified at least five new zones of copper and / or tin mineralisation that have not previously been recognised.”

.

BACKGROUND

  • Following the recent successful exploration drilling at South Crofty, which demonstrated high-grade tin mineralisation at depth including 2.6 m at 10.33% tin (“Sn”),, Cornish Metals has now assayed the remainder of the core drilled by Cornish Lithium earlier in the year at United Downs, located 8km east of South Crofty.
  • Cornish Lithium drilled two deep diamond drill holes (GWDD-001 and GWDD-002) to test for lithium in brine potential on Cornish Metals’ mineral rights area at United Downs.
  • The two drill holes were collared approximately 200 m apart and were drilled towards the south between the historic United Mines (to the south) and Great Consolidated Mine (to the north).
  • Map 1 shows the collar locations and traces of the drill holes in relation to surrounding mines and mine workings.
  • On April 15, 2020, the Company reported high-grade copper / tin mineralisation in drill hole GWDD-002 (14.69 m grading 8.45% copper (“Cu”) and 1.19% Sn between 90.6 m – 105.29 m downhole depth) from a zone referred to as Lithium Lode. See company news release dated April 15, 2020.
  • Due to COVID restrictions, the Company was unable to log and sample GWDD-001 and the remainder of GWDD-002 until recently.

.

GWDD-001

GWDD-001 was drilled to a total downhole depth of 1,097.4 m. Based on knowledge of the historic workings and the dominant orientation of the mineralised structures mined in the area, this drill hole was collared in the footwall of the Lithium Lode (high-grade copper / tin) (see drill section here). The hole intersected 6.91 m grading 0.81% copper which is believed to be the down dip extension of “Hot Lode”, one of the principal structures exploited by the historic United Mines.

.

GWDD-002

GWDD-002 was also drilled towards the south and was collared approximately 200 m west of GWDD-001 (see plan map here). In total, it intersected six different mineralised zones, including two new high-grade copper / tin zones:

  • The previously reported “Lithium Lode” returned 14.69 m grading 8.45% Cu and 1.19% Sn.
  • One of the newly discovered lodes returned 4.04 m grading 4.44% Cu and 2.06% Sn.
  • Further drilling is required to establish the three-dimensional relationships between these structures and the historic workings.

.

GEOLOGY AND MINERALISATION

The United and Great Consolidated mines operated between approximately 1757 and 1872 and were principally high-grade underground copper mines (grades reported to be in the order of 7% copper).

The exploration hypothesis for United Downs is that significant high-grade tin potential exists beneath the proven area of copper mineralisation, as demonstrated by South Crofty and several other economically mineralised areas of Cornwall.

ABOUT CORNISH METALS

Cornish Metals (formerly Strongbow Exploration Inc) completed the acquisition of the South Crofty tin and United Downs copper / tin projects, plus additional mineral rights located in Cornwall, UK, in July 2016. The additional mineral rights cover an area of approximately 15,000 hectares and are distributed throughout Cornwall. Some of these mineral rights cover old mines that were historically worked for copper, tin, zinc, and tungsten.
