NQ Minerals Increase in total gold resources at Beaconsfield gold mine

NQ Minerals Plc (AQSE:NQMI), the base and precious metals producer from its flagship Hellyer Gold Mine in Tasmania Australia, has today announced that total gold Resources at the Beaconsfield Gold Mine in Tasmania have increased to 1.454 million tonnes at 10.3 g/t for 483,000 ounces of gold.

Importantly, this new Beaconsfield Resource is calculated only for the section of the mine from 415 metre level down to 1,500 vertical metres, and the ore body remains open at depth. The deepest hole returning 2.5 m at 32.4 g/t gold. No resources have yet been calculated for the rich upper section of the mine which was mined from 1877 – 1914. Historically this upper section of the mine recovered 855,000 ounces of gold at 24 g/t during this period.

A review by Tasmanian independent consultants Pitt & Sherry of the metallurgical accounts available at the Beaconsfield mine site indicates that there is approximately 67,000 ounces of contained gold in Beaconsfield’s Tailings Dam #1. The tailings comprise a mixture of flotation tailings and leached tailingsfrom Beaconsfield’s operations from 1999-2012. The Beaconsfield operation experienced a number of equipment failures and process plant design deficiencies that resulted in poor recoveries in the first 3 years of operation. An assessment is underway to determine the ability to economically reprocess some or all of the tailings based on processing and knowledge advancements.

Key Points

·    Total Resource at the lower section of Beaconsfield Gold Mine in Tasmania, Australia, increased to 1.454 million tonnes grading 10.3 grams per tonne (g/t) for 483,000 ounces of gold.

·    An additional 67,000 ounces of gold potential exists in Tailings Dam #1.

·    Significant additional gold potential still to be assessed in the upper section of the old Beaconsfield Mine workings from surface to the 415 metre level plus the orebody remains open at depth below 1,500 metres.

·    “Beaconsfield is a rich gold deposit with genuine scale. The deposit is open at depth and there is significant potential to increase these resources with further drilling.” – NQ Minerals Plc’s Chairman David Lenigas.

David Lenigas, NQ’s Chairman, stated:

“The publishing of this new resource statement clearly demonstrates the huge underlying potential at Beaconsfield and highlights the immense scope for ongoing growth in the gold inventory as NQ moves this mine forward back in to production. In this regard, we believe that Beaconsfield offers a genuine opportunity for the Company to rapidly develop a high-quality gold asset not only for its shareholders but for Tasmania in general. We are almost complete with our due diligence process on this asset and are focused on bringing this famous and iconic Tasmanian gold mine back into production.”

About the Beaconsfield Gold Mine

The Tasmania Mine (Now referred to the Beaconsfield Gold Mine) is located 40 km north-west of Launceston in the town of Beaconsfield in Tasmania, Australia. The Tasmania Mine area is covered by Mining Lease 1767P/M.

Mining at Beaconsfield is centred on the Tasmania Reef. Prospectors discovered the Tasmania Reef in 1877. Mining between 1877 and 1914 yielded 854,600 ounces of gold at an average grade of 24.3 g/t. During this time, mining occurred between surface and 455 metres. Eventually, dewatering difficulties caused mine closure.

Modern exploration commenced in 1970. In the early 1990’s, a joint venture was established between Allstate Explorations and Beaconsfield Gold NL and a feasibility study commissioned. Following this study, production re-commenced in 1998 after 84 years of inactivity with around 1.8 million ounces of gold recovered since 1877.

The 350,000 tonne per annum capacity gold processing plant is currently under care and maintenance.

NQ is acquiring the Beaconsfield Gold Mine as previously announced on 21 February 2020.

NQ plans to re-open the mine by developing a new modern mine 3.6 km decline access into the Beaconsfield Mine from surface to reconnect into the existing mine workings at the 430 metre level. This new decline will be capable running large modern mining equipment and men/materials/rock from surface to anywhere in the mine environment and will allow for efficient low cost operations into the future.

Details of New JORC 2012 Mineral Resource Estimate

An independent review of the underground gold resources available at Beaconsfield has been Groundwork Plus Pty Ltd for Pitt & Sherry on behalf of NQ Minerals Plc.

Note: The full Mineral Resource Estimate Report is available on the NQ’s website. This Report also includes the JORC tables required for the reporting of Mineral Resource Estimates.

The grade estimates have been classified in accordance with the guidelines set out in the Australasian Code for Reporting of Mineral Resources and Ore Reserves (JORC Code, 2012). Resource categories were assigned based on geological interpretation, data quality, data density and estimation quality. The following table represents the Mineral Resource as at 30 April 2020 for the Tasmania Mine. The resource has been compiled by Troy Lowien as a Competent Person as required by the JORC Code.

The Resource estimate for the Tasmania Mine has been classified as Indicated and Inferred Mineral Resources in accordance with guidelines as set out in the Joint Ore Reserves Committee (JORC) Code (2012). Resource categories have been defined using definitive criteria determined during the validation of the grade estimates, with detailed consideration of the JORC Code categorisation guidelines.
