Award of Tambo South tenement

ECR Minerals plc (AIM: ECR), the gold exploration and development company focused on Australia, is pleased to announce that it has been awarded Exploration Licence EL007486 ("EL007486" or the "Tambo South Licence") in Victoria, a tenement located directly to the South of its Tambo project.

Highlights

·    New licence considerably extends the Tambo project area with the two tenements covering a contiguous strike of 47km

·    Gold, tungsten and copper have all been historically reported in the Tambo South Licence area

·    Neighbouring Haunted Stream Goldfield has recorded encouraging drilling results on a shear zone that is believed to pass into the Tambo South Licence area

·    Under explored alluvial prospects tie into ECR's growing expertise from its Queensland projects

EL007486, which has been granted for an initial 5-year term, covers an area of 322 km². The majority of the title encompasses Crown Land and ECR has also signed a standard Native Title Agreement with the Gunai-Kaurnai People.

The Tambo South Licence is situated approximately 35km NE of the township of Bairnsdale in the eastern part of Victoria, Australia, also known as 'Gippsland'. Minerals historically reported to be contained within EL007486 include gold, tungsten and copper. This new title abuts ECR's existing Tambo licence (EL007484) and importantly both tenements cover a contiguous strike of 47km.

Figure 1 illustrates the regional shear zones which are thought to pass through both titles EL007484 and EL007486.

Initial analysis by ECR has identified the following areas of interest:

1.    Haunted Stream Fault: Hosts the historic Haunted Stream Goldfield which lies outside the western boundary of the new title EL007486. Drilling at this Goldfield was undertaken by First Au Ltd (ASX: FAU) with intercepts including 0.2m @ 36.88 g/t Au and 10.7m @ 3.05 g/t Au.  The ECR board believes that this same shear zone passes into EL007486.

2.    Tambo Crossing: Historical reporting of the mining of Wolframite (Fe-Mn Tungsten) in numerous shallow small pits within the EL007486 tenement.

3.    Mt Elizabeth: Mt Elizabeth is an acid intrusive geology. Previous explorers in the 1970s and 1980s, including Freeport and CRA, identified the outer contact of this intrusive to be anomalous in base metals (primarily copper).

4.    Shady Creek: The south western region of the new EL007486 title has recorded previous alluvial gold workings. This area has seen little attention in the way of targeted modern exploration.

5.    Peters Creek: This area south of Mt Elizabeth in the new EL007486 title and on the postulated strike of the Haunted Stream Fault has notable alluvial and sulphide rich gold deposits.

Planned Exploration

The first phase of exploration is planned to include grassroots stream sampling, rock chip sampling and LIDAR (Light Detection and Ranging) acquisition. The Company's focus will be within areas on the projected shear zones. The ECR board is currently determining the best way to include EL007486 into its existing work programme, where the key priorities remain Raglan, Blue Mountain and Lolworth.

ECR's Chairman, Nick Tulloch, commented: "We are pleased to confirm the extension of our Tambo project area with the award of this new tenement - an application that we had been seeking for some time in conjunction with our project planning for this region.

"EL007486, or Tambo South, is considered to host multiple opportunities and increasing activity within the Gippsland area supports our thesis that our new tenement can expand ECR's operations, including potentially through a largely under-explored alluvial opportunity.

"Across our other projects, I am pleased to report continuing operations at Raglan in Queensland alongside further planning for forthcoming activities at Blue Mountain and Lolworth.  We also expect to publish our annual report later this week which will include a more detailed review of our strategy."

Furthermore, it has also submitted a licence application at Kondaparinga which is approximately 120km² in area and located within the Hodgkinson Gold Province, 80km NW of Mareeba, North Queensland.

Following the sale of the Avoca, Moormbool and Timor gold projects in Victoria, Australia to Fosterville South Exploration Ltd (TSX-V: FSX) and the subsequent spin-out of the Avoca and Timor projects to Leviathan Gold Ltd (TSX-V: LVX), ECR Australia has the right to receive up to A$2 million in payments subject to future resource estimation or production from these projects. 

ECR Australia also has approximately A$76 million of unutilised tax losses incurred during previous operations.
