Encouraging Redmoor Phase 1 Drilling Results

Joint Venture Partners Commit to Phase 2

 

Strategic Minerals plc (AIM: SML; USOTC: SMCDY), the diversified mineral production and development company, is pleased to announce the results from the first 10 holes of the Phase 1 diamond drilling programme at the Redmoor Tin-Tungsten Project being undertaken through its joint venture vehicle Cornwall Resources Limited ("CRL").

 

HIGHLIGHTS

               

·  Successful high-grade tin and tungsten intersection in Johnson's Lode and in Kelly Bray Lode

 

·  Great Southern Lode re-interpreted as a high-grade part of the Sheeted Vein System ("SVS")

 

·  Encouraging results from discrete high-grade zones within the SVS mineralisation

 

·  SVS high-grade zone widths and grades exceeding CRL's expectations. Exceptional intercepts include:

 

CRD007:

14.8 m @ 1.00 % SnEq from 245.7 m, including 2.5 m @ 3.39 % SnEq from 257.9 m

CRD009:

17.5 m @ 0.68 % SnEq from 265.9 m, including 3.1 m @ 1.97 % SnEq from 280.3 m

CRD009:

28.2 m @ 0.81 % SnEq from 298.8 m, including 7.0 m @ 1.89 % SnEq from 317.5 m

CRD010:

11.1 m @ 0.57 % SnEq from 113.3 m, including 3.1 m @ 1.19 % SnEq from 121.3 m

 

·  Re-examination of historical (1980's) drilling results has identified 31 significant intercepts within SVS high-grade zones

 

· Phase 2 exploration re-focused on further defining the high-grade zones within the SVS as these are potentially an economically attractive target for underground mining

 

·  CRL's joint venture partners, have committed a further £150,000 to continue the first three additional holes in Phase 2 and have committed to complete an additional 3 holes should they be required

 

·  All drilling is expected to be completed and reported upon in Q4, with a Resource Update expected to be released in Q1 2018

 

·  Ongoing positive community support with Cornwall Council extending drilling consent to 31 October 2017

 

 

Commenting, John Peters, Managing Director of Strategic Minerals, said:

               

"The initial 10 holes of the 2017 drill programme at Redmoor have shown encouraging results causing the joint venture to re-assess the most beneficial drilling targets for Phase 2.  The results have caused a re-focus in our thinking that the high-grade zones within the sheeted vein system may prove a superior underground mining prospect when compared to the original, narrow, high-grade lodes.

 

"The team at Redmoor has done an outstanding job and has recommended a further three to six holes for Phase 2 exploration.  This proposal has been agreed to by both joint venture parties and is now progressing.

 

"We look forward to bringing the market further news on the progress at Redmoor later this year and in the first quarter of 2018."

 

2017 Drilling Programme

 

Phase 2 drilling is expected to be completed by the end of October 2017.  The remaiming Phase 1 and Phase 2 results (18-21 holes in total, including the first 10 Phase 1 holes reported here) are expected to be reported on in Q4 2017 with an updated Resource Estimate expected in Q1 2018.

SVS High-Grade Zone Significant Intercepts

 

CRD007:

14.8 m @ 1.00 % SnEq from 245.7 m, including 2.5 m @ 3.39 % SnEq from 257.9 m

CRD009:

17.5 m @ 0.68 % SnEq from 265.9 m, including 3.1 m @ 1.97 % SnEq from 280.3 m

CRD009:

28.2 m @ 0.81 % SnEq from 298.8 m, including 7.0 m @ 1.89 % SnEq from 317.5 m

CRD010:

11.1 m @ 0.57 % SnEq from 113.3 m, including 3.1 m @ 1.19 % SnEq from 121.3 m

 

The thicknesses quoted above, and all other thicknesses in this report are, unless otherwise stated, apparent thicknesses. Estimated true thicknesses are shown in Appendix 1. For convenience, intersections are also expressed in terms of a calculated tin equivalent value1 (SnEq). While the ideal orientation to drill the SVS is orthogonal to the dominant vein orientation, one hole (CRD007) was drilled to investigate the dip-extent of the zone, and returned comparable thickness and grade to that of nearby holes drilled perpendicular to the dominant vein. 

 

Holes CRD008 and CRD006 tested for a western extension of GSL / SVS. Low-grade but anomalous mineralisation was intersected, which is interpreted evidence of continuity of the SVS mineralising system in this area. CRL's geologists believe that, due to a combination of 25˚ westward plunge and possible movements on cross-cutting NNW-SSE faults, the high-grade zones of the SVS are deeper at this distance to the west; it is possible that a deeper hole beneath the profile containing CRD008 and CRD006 might identify additional higher-grade mineralisation further to the west of that currently defined.

 

[1] Equivalent metal calculation notes; Sn(Eq)% = Sn%*1 + WO3%*1.43 + Cu%*0.40. Commodity price assumptions: WO3 US$ 33,000/t, Sn US$ 22,000/t, Cu US$ 7,000/t. Recovery assumptions: total WO3 recovery 72%, total Sn recovery 68% & total Cu recovery 85% and payability assumptions of 81%, 90% and 90% respectively.

 

South West Minerals Historical Drilling: SVS High-Grade Zone Significant Intercepts

 

SVS High-Grade Zone Exploration Potential

High-Grade Lodes

 

Johnson's Lode

 

Great South Lode

 

Great South Lode is a narrow, high-grade lode which outcrops south of the SVS and which dips to the north and is believed to have been historically mined over only a limited extent.

 

Kelly Bray Lode

 

Kelly Bray Lode is a narrow high-grade lode which outcrops further to the north of Johnson's Lode and which dips to the south and has been historically mined over a length of over 400 m and to a depth of approximately 300 m.

 

Only one significant intercept within Kelly Bray Lode has been drilled so far in the 2017 drilling programme.  This was CRD004, detailed in Appendix 1 (b), which showed an intercept of the Kelly Brade Lode for  0.6 m @ 0.95 % SnEq from 212.3 m.

Notes to Editors

 

Strategic Minerals Plc is an AIM-quoted, diversified mineral development and production company with projects in the United States of America, the UK and Australia. The Company is focused on acquiring and developing cash generative, high quality projects which meet local market demand for commodities and utilising this cash flow to undertake value added exploration. 

 

In September 2011, Strategic Minerals purchased its first cash generating asset; the Cobre magnetite tailings dam project in New Mexico, USA which it brought into production in 2012 and which continues to provide a revenue stream for the Company. The portfolio was expanded in January 2016 with the acquisition of shares in Central Australian Rare Earths Pty Ltd, which holds tenements in Western Australia and the Northern Territory that are prospective for cobalt, gold, nickel sulphides and rare earths. The Company has since acquired all shares in Central Australian Rare Earths Pty Ltd. In May 2016, an additional exploration asset was acquired when the company entered into an agreement with New Age Exploration Limited to acquire up to 50% of the Redmoor Tin/Tungsten project in Cornwall, UK. This 50% acquisition has now been completed and drilling at the project has commenced.

1CRD003 targeted at Kelly Bray Lode, failed to identify a lode structure due to intersecting a significant cross course. Prior to this encountered a previously unknown zone of anomalous, northerly dipping sheeted veins.

2CRD004 targeted at the western extension of Kelly Bray Lode, intersected an unanticipated void space with copper impregnation on the margins. True thickness is from sample + void geometrically adjusted for dip of interpreted lode. This is interpreted to be Blair's Lode

3CRD008, investigating the western extent of the SVS hit mineralisation beneath an unexpected 6.10 m void. This is 150 m from the nearest known workings. True thickness unknown, but likely to be wider than intersection thickness due to adjacent mined out void.
