Leigh Creek assay results support the successful infill drilling at Paltridge North

Strategic Minerals plc (AIM: SML; USOTC: SMCDY), a producing mineral company actively developing projects prospective for battery materials, is pleased to announce the assay results from the full diamond drill programme at Paltridge North and the first diamond drill hole from Rosmann East. The Paltridge North assays support the historic results and highlight areas of higher-grade copper (including 1m @ 8.7%). The Initial Rosmann East hole extends mineralisation significantly below the existing pit floor and an additional 6 holes have been completed with results to follow.

Highlights:-

· Paltridge North infill diamond drill programme has been completed with the aim of providing metallurgical test samples, testing historic drilling and geotechnical testwork

· 8 of the 10 holes intersected significant copper mineralisation including malachite, azurite, chalcocite and native copper

· Significant intersections include;

o PND18-04: 26.2m @ 1.14% Cu, including 11.2m @ 1.85% Cu

o PND18-06: 28.4m @ 1.17% Cu, including 4.3m @ 3.6% Cu

o PND18-07: 24.0m @ 1.15% Cu, including 8.9m @ 2.8% Cu

· 6 of the 10 holes have an intersection average of 1.34% which is significantly greater than the resource average of 0.81%

· Reinforces previous Paltridge North resource model estimate

· Rosmann East extension drilling has been completed with 7 diamond drill holes testing below existing pit floor

· First Rosmann East hole provides strong support for continued mineralisation 60m below existing pit floor and 30m below previous drilling, with RED18-01 returning 69m @ 0.37% Cu

· Results from other holes at Rosmann East, which have targeted known areas of higher grade, will be released when available.

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

"The Paltridge North deposit assays, arising from the first diamond drilling programme for 32 years, have delivered better than expected results and provide the SML Board confidence that Paltridge North could be a significant copper producer in the near future.

"Additionally, the assays from the first hole at the Rosmann East deposit support potential additional mineralisation below the existing open pit floor. This is good news due to the ease of accessibility to this ore.

"Management and the Board look forward to restarting the Mountain of Light operations in the first half of 2019 and moving into long term, higher volume production at a later date."

1.1 Paltridge North Infill Drill Programme

Ten PQ3 (83mm diameter) diamond drill holes, for a total of 496.2m, were completed at Paltridge North in August 2018 with the aim of providing metallurgical samples, resource confirmation and geotechnical data for the feasibility study due for completion in the latter half of 2019. The assays have been received as part of the metallurgical testwork and are summarised below.

1.2 Results

The full assay results are now available and are summarised in the table below. All holes intersected oxide copper mineralisation (malachite and azurite) as expected, and eight holes continued into chalcocite mineralisation, with some native copper being observed in the core. The mineralised intersections contain a number of high grade intervals with a best of 1m at 8.7% Cu in PND18-07.

[1] Intervals are downhole however most holes are drilled perpendicular to the deposit orientation

3 PND18-01 has not been assayed in order to provide typical core for viewing and assessment by potential mining contractors

The Paltridge North deposit is a relatively flat tabular deposit hosted in a fine-grained siltstone. Mineralisation has varied from predominantly copper oxide minerals, malachite and azurite, in the upper levels of the deposit grading into a relatively sharp contact where the copper minerals are predominantly chalcocite with some minor native copper observed in the drill core. Only minor bornite and chalcopyrite have been identified in core to date.

6 of the 10 holes assayed have an average intersection grade of 1.34% which is significantly greater than the current resource average of 0.81%. Given the infill nature of the drilling, this may not reflect an equivalent uplift in the resource grade but provides encouragement for high grade zones in the Paltridge North deposit.

1.3 Further Work

The results are generally of the grade and width predicted by the existing resource model and therefore provides confidence that the historic drilling is representative of the Paltridge North deposit. An updated resource model, which will incorporate these results, is in the process of being generated with a new resource estimation expected for completion in March 2019. The results will be released when they become available.

Metallurgical testwork on the samples obtained from the drilling is ongoing.

1.4 Rosmann East Drilling

Seven PQ3 diamond holes for a total of 675.2m were completed at Rosmann East in January 2019 with the aim of testing for extensions to existing copper oxide and chalcocite mineralisation zones beneath the existing open pit. This drilling is also designed to provide metallurgical samples and geotechnical information for a feasibility study on the Rosmann East deposit. The shallow nature and proximity to the Mountain of Light processing plant makes mineralisation from Rosmann East an attractive ore source for initial production.

1.5 Results

Assay results for the first hole, RED18-01, are now available and are tabulated below. This hole was drilled from the existing pit floor and intersected low grade chalcocite mineralisation (with minor pyrite, chalcopyrite and bornite) from 11m through to 72m, then an 8m wide zone of oxide mineralisation (malachite and azurite) against a faulted contact with an intrusive diapiric breccia.

Table 2 - Rosman East RED18-01 Assay Results

These results support and expand on the previously reported results from the two reverse circulation holes drilled from the bottom of the Rosmann East pit in October 2018:

· RERC18-01: 12-62, 50m at 0.43% Cu

· RERC18-02: 13-67, 54m at 1.41% Cu

RED18-01 demonstrates that copper mineralisation extends to at least 60m below the current pit floor and approximately 30m below the previously deepest known mineralisation.

Notes to Editors

Strategic Minerals Plc is an AIM-quoted, operating minerals company actively developing projects prospective for battery materials. It has an operation in the United States of America and development projects in the UK and Australia. The Company is focused on utilising its operating cash flows, along with capital raisings, to develop high quality projects aimed at supplying the metals and minerals being sought in the burgeoning electric vehicle/battery market.

In September 2011, Strategic Minerals acquired the Cobre magnetite tailings dam project in New Mexico, USA, a cash-generating asset, which it brought into production in 2012 and which continues to provide a revenue stream for the Company. This operating revenue stream is utilised to cover company overheads and invest in development projects orientated to supplying the burgeoning electric vehicle/battery market.

In January 2016, the portfolio was expanded 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 earth elements. The Company has since acquired all shares in Central Australian Rare Earths Pty Ltd. In September 2018, the Company entered contracts for the sale of certain CARE tenements that have been identified as gold targets.

In May 2016, the Company entered into an agreement with New Age Exploration Limited and, in February 2017, acquired 50% of the Redmoor Tin/Tungsten project in Cornwall, UK. The bulk of the funds from the Company's investment were utilised to complete a drilling programme that year. The drilling programme resulted in a significant upgrade of the resource. The 12-hole 2018 drilling programme has been completed and the subsequent resource update was announced in February 2019.

In March 2018, the Company completed the acquisition of the Leigh Creek Copper Mine situated in the copper rich belt of South Australia and is currently working to bring this into operation in 2019.
