Greatland Gold PLC (AIM:GGP) Exploration Programme Commences at Ernest Giles East


Greatland Gold plc (AIM:GGP), the precious and base metals exploration and development company, is pleased to announce that a Mobile Metal Ion (“MMI”) surface geochemistry survey has begun at Ernest Giles East. In addition, a ground gravity survey across Ernest Giles East is expected to commence within the next few weeks. Results of the exploration programme are expected to be disclosed in September 2017.

Surface Geochemistry and Ground Gravity Surveys Seek to Demonstrate Prospectivity of Virtually Unexplored New Eastern Licences


·     Exploration work seeks to demonstrate the broader potential for gold mineralisation;

·     Greatland’s technical team has begun a 3.2 kilometre by 400 metre spaced MMI survey, and the Company expects to commence a 1.6 kilometre by 200 metre spaced gravity survey across the same area within the next few weeks;

·     Results from these surveys will be used to establish gold exploration targets on these new licences for follow up work and drilling.

The Ernest Giles East area covers approximately 600 square kilometres, including a large 80km long north-south trending sequence of rocks which represent an extension of the gold prospective Ernest Giles greenstone sequences. This exploration programme follows on from recent significant developments at the project including the identification of two large zones of gold mineralisation (announced 12 and 19 January 2017) at the Meadows target in the south-west corner of the project, and an agreement with Newmont Exploration Pty Ltd, a subsidiary of Newmont Mining plc (NYSE:NEM), one of the world’s largest gold producers (announced 16 May 2017).

Gervaise Heddle, Chief Executive Officer, commented“This survey is a natural progression following successful demonstration last year of the presence of large zones of gold mineralisation on the Western side of the Ernest Giles project. We hope that this new exploration programme will highlight the prospectivity of the new Eastern licences, licence areas where virtually no modern exploration has taken place, and confirm our belief in the potential of this exciting new gold district to host several multi-million ounce deposits.”

Overview of Ernest Giles Project

The Ernest Giles project is located in central Western Australia, covering an area of more than 1,800 square kilometres that includes over 200km of strike of gold and nickel prospective rocks. The area is covered by desert sands and sediments, making it virtually unexplored. The region is home to several successful exploration discoveries such as Tropicana (AngloGold ASX:AGG), which contains over 7 million ounces, and Yamarna/Gruyere (Gold Road Resources ASX:GOR), with over 6 million ounces. The Company is targeting large +5m ounce deposits and clusters of several camp-type +1m ounce gold discoveries at Ernest Giles.

Earlier drill programmes by the Company at Ernest Giles intersected gold mineralisation and large alteration systems in wildcat drilling of blind structural targets defined by airborne geophysics. This was considered a major achievement for such a large prospective area with virtually no historical work.

In late 2016, the Company completed a comprehensive broad spaced Reverse Circulation “RC” drilling programme at Meadows in the south-east of the project area which tested several large areas based on work completed by the Company and earlier work by Western Mining Corporation. This RC drill programme comprised 23 holes for 5,581m. Holes were drilled on a broad spaced grid pattern of 1,600m x 800m.

Mineralisation was observed in 13 of the 23 holes and several holes exhibited gold anomalous zones over tens of metres, peaking at 0.78g/t gold with mineralisation at end of hole. Two large zones of mineralisation were identified; Western 6km x 1.5km and Eastern 2km x 1.5km. Additional 1m sampling of several intercepts was undertaken to confirm preliminary results and better define mineralisation with many significant gold results returned up to 2g/t. Results confirmed mineralisation is present over a large area at Meadows and suggest that Greatland has discovered a new gold province in this largely unexplored region.

In late 2014, the Company completed a restricted programme of MMI surface geochemistry over several target areas which were outlined from interpretation of detailed aeromagnetics. Sample spacing was at a nominal 800m x 200m. Results from this sampling were positive over the Meadows area (peaking at 68ppb gold), and at the Empress area. At Empress many samples returned +5ppb gold, which is quite high for MMI results, plus several above 40ppb gold peaking at 338ppb gold at the eastern extremity of three consecutive sample lines potentially outlining a significant anomaly 3km long by 1km wide which remains open to the east.

It should be noted that the Ernest Giles project area covers over 1,800 square kilometres and is host to a number of other high priority targets such as Wishbone (a high priority structural target), and Maple (a coincident MMI and structural target in the west of the project area).

The recent acquisition of additional ground sees Greatland dominating the landholding in the region. Over 800 square kilometres of new acreage was acquired to cover extensions of known prospective sequences which are an integral addition to the project. Success from previous work over recent months has demonstrated the potential of the region to host very large mineralised systems and securing further ground is an important step for the overall development of the project.

A detailed airborne survey was recently acquired over the new areas, particularly over the northern sequences and the newly acquired Ernest Giles East block which includes a 600 square kilometres area covering an 80km long north-south trending sequence of rocks that represents a continuation of the gold prospective greenstone sequence.

A comprehensive ground gravity survey was completed over parts of the Western licences at a station spacing of 1,600m x 200m. Data was collected over the Empress, Wishbone and greater Meadows area. The ground gravity data integrated with airborne magnetics has highlighted several additional targets conducive to gold mineralisation at each of the areas surveyed.

Greatland has commenced initial work over the Eastern block. The Eastern block, covering 600 square kilometres, represents an extension of the gold prospective Ernest Giles greenstone sequences. Work includes geological reconnaissance along with broad spaced gravity traverses and orientation MMI sampling. Gravity work will be carried out initially at a nominal station spacing of 1,600m x 200m. Orientation MMI sample traverses will be completed on 3,200m x 400m centres with results to be assessed in conjunction with aeromagnetic and gravity data. We expect integration and review of these data sets to be complete during September.

Greatland’s successful efforts to date have highlighted the potential of the Ernest Giles project to host several, very large, mineralised systems.

In May 2017, Greatland entered into an agreement with Newmont Exploration Pty Ltd, a subsidiary of Newmont Mining Corporation (NYSE:NEM) over the Ernest Giles project.
