Interim Report

For the six months to 30 June 2023

Below are Great Western Mining Corporation PLC's Annual Report and Financial Statements for the half year ended 30 June 2023.

Great Western Mining Corporation PLC ("Great Western" or "the Company") explores for, appraises and develops mineral resources on its claims in the state of Nevada, USA but currently has no revenues from its operations.  Accordingly it is reporting a loss after tax of €527,985 for the half year ended 30 June 2022 (30 June 2022: €448,652; 31 December 2022: €792,263).  At the end of the period Great Western's net assets were €8,845,494 (30 June 2022: €9,191,466; 31 December 2022: €8,618,024) with no debt apart from trade creditors in the normal course of business.  Net current assets were €609,925 (30 June 2022: €1,304,459; 31 December 2022: €418,084).

During the half year, Great Western's principal focus has been on the construction of a mill to process gold and silver concentrates from tailings, spoil heaps and stockpiles which are present in abundance on the Company's claims.  In parallel, since the start of the work season two geologists have been working continuously in the field conducting sampling and mapping, initially over the Olympic Gold Project and subsequently in the Huntoon Valley area where the emphasis has been on copper prospects.  A single hole was drilled at the OMCO Mine prospect (Olympic Gold Project) with a diamond core rig.  Since the period end an RC rig has been moved to Mineral Jackpot, using the new mountain road constructed by the Company in 2022, where drilling was halted for mechanical reasons but will resume as soon as the drill crew is available.  In January the Company conducted a placing of new shares for cash which raised £800,000 before expenses and since the period end conducted a further placing to raise £500,000 before expenses.

Process Mill

Great Western is in a 50-50 joint venture with local mining contractor Muletown Enterprizes LLC.  The joint venture is known as Western Milling LLC and has been set up to establish a milling operation for producing precious metal concentrates.  The project, which is due on production this year, has faced some strong headwinds during the period and since the period end.  Notably, Nevada faced a severe winter which lasted over two months longer than the average, including late season heavy snowfalls, followed by heavy rainfall and mudslides in the spring and, more recently, a severe and unusual tropical storm.  Operationally, environmental regulations call for the concrete required as a base for the milling plant to be laid in one continuous pour to prevent possible pollution of the subsoil.  It has proved logistically extremely difficult to achieve this single pour, due to a lack of material in the area and local labour shortages.  However, this concrete pour was satisfactorily completed in September, allowing for commencement of plant assembly on site for first production, which can commence once Western Milling has been issued with a permit from the state environmental authorities.  Upon filing an application early in the year, the joint venture was advised that there would be a 6-month wait for approval but in August was further notified that this period would be delayed for 2-3 months due to personnel shortages and pressure of work at the regulator. Such approval waiting times are beyond the Company's control, but the joint venture is not aware of any problems with its application.  In the meantime, all steps will be taken to ensure that producing operations can commence as soon as the approval has been received.  

Geology - Field Work and studies

Coinciding with the late start of the work season, two American geologists joined Great Western's US payroll working under the direction of the Company's Exploration Manager, Dr. James Blight, with an initial task of carrying out sampling and mapping over the Company's claims and to achieve a better understanding of outlying claim areas.  This field work will continue until at least the end of October and a wealth of very interesting new data has already been acquired for analysis.  At the Olympic Gold Project, the large, undrilled Rhyolite Dome prospect in the south of the claims group is proving to be of great interest and a potential candidate for geophysical studies followed by drilling.  More recently, extensive sampling and mapping has been carried out in the Huntoon Valley and at the M4 prospect where only limited drilling has so far been carried out by Great Western.  

Copper Potential

Great Western's claims are rich in a variety of minerals.  Recently the Company's focus has been on the potential of precious metals but in an earlier era the Company drilled approximately 5,000 feet (1,524 metres) of hole in the search for copper, mostly on the M2 claims in the Black Mountains Group but to a limited extent also on the M4 claims and in the Huntoon Valley on the Crown Point claims.  An independent resource study, prepared in compliance with JORC, was commissioned for the M2 programme and this reported, on a partly inferred/partly indicated basis, 4.28 million tonnes grading at 0.45% copper, effectively 19,000 tonnes of copper.  While a material quantity, a viable commercial development requires a greater volume than this which, in the Company's opinion, can be achieved by drilling over a considerable distance in both a northwesterly and southeasterly direction from the existing mapped resource.  In addition, there is an area within the existing reported resource at M2 which was not drilled in the past due to permitting limitations, now resolved.  Away from M2, the field work currently ongoing provides strong indications, yet to be proved by drilling, of similar sized potential deposits in the Huntoon Valley and at the M4 prospect.   

For ease of understanding, the resource and prospects at M2, the prospect at M4 and the Huntoon Valley prospect, which are adjacent to one another, have collectively been designated the 'Huntoon Copper Project' ('HCP'), for exploration as a single entity, even though linkage between the three has not been (and may not be) established.  

While Great Western may drill electively on the HCP, the scale of its potential calls for capital are beyond the capability of a company of Great Western's size to raise in its own right.  Great Western has talked to and hosted several third parties with a view to participating in the HCP but has yet to secure a partner.  The intensive work conducted by the Company this year, which is ongoing, is aimed at providing a stronger basis for a tie-up with a third party.  In October, a well-reputed consultant specialising in copper prospects of this nature will visit the HCP to review the work over the last year and make recommendations for the next steps.     

Drilling

In April, a diamond core rig was used to twin the successful RC hole which identified the OMCO vein in 2022, in an attempt to improve the quality of the result achieved with an RC rig at the previous hole.  The results were satisfactory and confirmed the discovery, being similar to the original hole but not improved with the use of diamond core. The next stage of drilling is likely to be carried out with an RC rig which is less expensive than diamond core. In July an RC rig was mobilised to Mineral Jackpot on the 14 km access road constructed by the Company in 2022.  There were mechanical issues with this rig, not previously used by the Company, and work was suspended waiting on parts and repairs.  Drilling will continue once the rig is operational and a crew is available.

Looking Forward

The Company's immediate objective is to bring the processing mill on to production  this year.  Great Western will attempt to capitalise on the significant work carried out over the HCP this year and once the 2023 programme has been completed, analysed and reviewed, will launch a new initiative to source a partner for ongoing exploration, appraisal and potential development. No further drilling is likely to be initiated in 2023 beyond the current programme at Mineral Jackpot but prioritisation of gold and silver targets will be reviewed during the winter, once the process mill is up and running.
