Paterson Project - MMI Results from Scallywag Target

Greatland detects copper, silver, gold and supporting pathfinder elements in first round of MMI sampling over large Scallywag target

Greatland Gold plc (AIM:GGP), the precious and base metals exploration and development company, is pleased to announce results of Mobile Metal Ion ("MMI") sampling over the Scallywag gold and copper target.

The Scallywag target, located within the Company's 100%-owned Havieron licence, consists of several magnetic anomalies over a large area of approximately 6km by 4km, each with the potential to host gold, silver and/or copper mineralisation. MMI sampling over the Scallywag target was completed in late Q3 2018 and the results are reported below.

The Scallywag target was selected for the first phase of a new exploration programme in the Paterson designed to test the multiple regional targets, many with a similar geophysical signature to Havieron, that were identified by a review of regional geophysical and geochemical data conducted last year by Greatland (see announcements dated 13 August 2018 and 17 August 2017). Greatland's first drilling campaign at the Havieron target (6km east of Scallywag), returned excellent results including 121m at 2.93g/t gold and 0.23% copper from 497m (HAD001).

Highlights of MMI sampling results:

· Copper, silver and gold MMI responses detected along the western parts of the target area over a strike length of approximately 6km;

· Multiple pathfinder element responses (including arsenic, cerium and lanthanum) were also detected along this trend with several clusters of samples displaying a strong multi element response;

· Highest results returned from MMI sampling included 2750ppb copper, 8ppb silver, 0.4ppb gold, 50ppb arsenic, 480ppb cerium and 280ppb lanthanum;

· The grouping patterns of certain elements, as seen in the MMI response over parts of the Scallywag target, are similar to those patterns seen in MMI and drill assays from the Havieron prospect.

Further interpretation of MMI results from Scallywag will be carried out in conjunction with detailed aeromagnetic and ground gravity data to refine targets prior to drill testing.

Gervaise Heddle, Chief Executive Officer, commented: "We are very pleased with the results from the first phase of our regional exploration programme which have reinforced the potential for Scallywag to host copper, silver and gold mineralisation. Scallywag represents a high priority target for further exploration given the large size of the target, its relative proximity to Havieron, and its potential to host the prospective basement sequence under relatively shallow cover at probable depths of around 50m."

"The Paterson region remains relatively underexplored and our licences host multiple large magnetic anomalies, similar in scale and structural setting to the Havieron target. We intend to continue our systematic programme of regional exploration over the course of the next 12-18 months."

The Paterson project covers more than 385 square kilometres in the Paterson region of Western Australia and includes the three licences of Havieron, Paterson Range East and Black Hills.

Limited historical drilling was conducted by Newcrest Mining Limited ("Newcrest") at Havieron during the 1990s and early 2000s where six holes were drilled, all of which intersected significant alteration and gold plus copper anomalism. Thick lower grade zones of gold and copper were intersected by Newcrest and gold grades within these peaked at 15.4g/t and copper to 2.5%.

In April and May of 2018, Greatland carried out its maiden drill campaign at the Havieron target which yielded excellent results including 121m at 2.93g/t gold and 0.23% copper from 497m (HAD001).

Overview of Paterson Project and Havieron licence including Scallywag target

The Company's Paterson project, comprising the Havieron and Paterson Range East licences, and the Black Hills licence, is located in the Paterson region of northern Western Australia. The three licences collectively cover more than 385 square kilometres prospective for iron-oxide-copper-gold ("IOCG") deposits and Telfer style gold deposits.

The Paterson region hosts several large gold and copper deposits such as Telfer and Nifty. The region has been subject to more recent exploration which has outlined several other deposits including Magnum (Au), Calibre (Au), O'Callaghans (Cu) and Maroochydore (Cu).

The region is remote, however infrastructure is good with several operating mines, roads, formed tracks and rail networks nearby which branch out from the regional industrial hub of Port Hedland 500km to the west.

The Paterson Province is the northern portion of the Proterozoic Paterson Orogen. More recent exploration throughout several Proterozoic Orogens within the western parts of the Australian continent has resulted in the discovery of the large Tropicana gold deposit and the large Nova nickel-copper deposit. Globally these Proterozoic Orogens are highly prospective for large deposits, and are often under-explored.

Alteration and mineralisation of those targets which have been drill tested at Havieron and Paterson Range East display similarities to IOCG-type deposits. Examples of these are the large Olympic Dam and Ernest Henry deposits in central and eastern Australia.

Initial airborne data outlined the Havieron target as covering approximately 1,000m x 1,000m. Depth to top of target is around 400m with these depths easily achieved with modern drilling equipment. Six drill holes were completed by Newcrest Mining Ltd between 1991 and 2005, all of which intersected significant hematite alteration and gold, plus copper anomalism. Thick lower grade zones of gold and copper have been intersected and gold grades within these peak at 15.4g/t and copper to 2.5%.

Following Greatland's review of regional geophysical and geochemical data over the Paterson project approximately fifty IOCG-type targets were identified in the broader region, with around half in ground held by the Company. The setting of these licences is on the western margin of a Proterozoic basin which ranges in depth from less than 100m below surface to more than 400m below surface. Basement rocks of the basin are predominantly calcareous rich sandstones intruded by several late stage granitic bodies exploiting basin margin faults which have also provided a focus for ore fluids. Historically, several of these targets have been subject to initial first-pass work and show promise at hosting mineralisation as seen at Havieron. The geophysical signature of these targets is very similar to that at Havieron. Basement rocks do not outcrop and Greatland has employed modern geophysical and geochemical methods to define targets prior to drill testing. The Scallywag target was identified from this regional review and hosts several magnetic anomalies over an area of approximately 6km x 4km with potential to host gold and/or copper mineralisation.

MMI sampling and ground gravity over the Havieron target was completed in late 2017 at an initial sample and station spacing of 200m x 200m. Additionally ground gravity was completed over the Scallywag target at a station spacing of 400m x 200m. Results of ground gravity and MMI work at Havieron outlined several targets with the peak gravity response not tested by existing drilling. Gravity data confirms a north-west structural trend of basement carbonate sediments which is mirrored by the surface MMI response. Clusters of elevated gold, silver, arsenic, copper and iron in MMI results are proximal the peak co-incident gravity and magnetic response. An elevated MMI response in pathfinder elements (cerium, lanthanum, uranium and lead) to the immediate SE of Havieron suggests primary basement mineralisation may be present along strike in a structural contact for up to 1.5 kilometres. Peak MMI responses over Havieron were 4ppb silver, 70ppb arsenic, 25ppb gold, 834ppb cerium, 710ppb copper, 53ppm iron, 284ppb lanthanum, 860ppb lead and 112 ppb uranium. Elevated pathfinder elements detected by the MMI survey support the view that Havieron may be an Iron Oxide Copper Gold type system. Gravity results from Scallywag show gravity highs co-incident with the magnetic targets over approximately 6km of strike.

Forward modelling of detailed aeromagnetic data (50m line spacing and 40m mean terrain clearance) and detailed ground gravity data (100m x 100m and 100m x 200m station spacing) over the Havieron target was completed by independent geophysical consultants in February 2018. Results of forward modelling defined a primary body approximately 600m x 600m across with a depth extent from 400m to 900m below surface resulting in a potential volume of more than 240,000,000 cubic metres. Results of forward modelling are indicative only as geophysical models are ambiguous, however modelled bodies were constrained to known physical rock properties and therefore potentially represent the core of the mineralised system at Havieron. Forward modelling suggests that of the six historic drill holes completed at Havieron only two intersected the target. Those two holes intersected only the very top of the mineralised system but returned over 100m of mineralisation (HAC9101) and over 50m of mineralisation (HAC9201) peaking at 15.4g/t gold and 2.5% copper within broad, lower grade intercepts.

In April and May of 2018, Greatland carried out its maiden drill campaign at the Havieron target completing four vertical core holes for a total of approximately 2,438m of drilling. Greatland's drill locations were designed to intersect the mineralised system at Havieron near to historical drill holes HAC9101 and HAC9201. Newcrest's historic drill holes HAC9101 and HAC9201 were vertical and drilled to depths of 533m and 528m respectively.

A plan showing the Havieron geophysical target and drill holes can be found at: http://greatlandgold.com/paterson/ 

Each of the four vertical core holes (HAD001-HAD004) penetrated recent desert sands and clays from surface to approximately 10-14m then Permian sandstones to 403-430m where the Proterozic target sequence was encountered. From top of Proterozoic, altered biotite rich rocks and calcareous sediments were intersected. Hydrothermal breccias and silica flooded mineralised zones persisted throughout. Laboratory analytical results returned peak gold of 137.69g/t and copper to 4.11% (HAD001). Broad mineralised intercepts of 121m at 2.93g/t gold and 0.23% copper from 497m, including 11.5m at 21.23g/t gold and 0.67% copper from 568.5m were noted (HAD001), and 21m at 3.79g/t gold 0.44% copper from 418m (HAD003). Holes HAD002 and HAD004 appeared to be in the periphery of the system; grades increasing with depth. These results demonstrate the large scale of the mineralised system at Havieron and the potential for high grades of gold and copper.

A new drill campaign at Havieron commenced on schedule in mid September 2018 (as announced 17 September 2018) and includes plans for approximately 6,000 metres of drilling to further determine the extent of mineralisation at Havieron. The new drill programme is expected to take ten weeks to complete. Downhole geophysical surveys will also be commissioned and executed during this time.

The first hole of Greatland's second drilling campaign at Havieron (HAD005) is complete. The hole was designed to provide structural and stratigraphic information along with indications of depth extent of the mineralised system at Havieron. HAD005 was collared 200m west of HAD001, angled at 70 degrees toward grid east, and projected to intersect mineralisation as seen at depth in HAD001. Geological inspection of HAD005 confirmed the hole has intersected approximately 239m of significant mineralisation, visibly similar to that previously intersected in HAD001, to a depth of 781m downhole (see Announcement dated 1 October 2018).

The Scallywag target lies approximately 6km west of the Havieron prospect within the Havieron licence. The Scallywag target, as defined by detailed aeromagnetics (50m line spacing) and ground gravity (400m x 200m) covers an area of approximately 6km x 3km. Interpretation of aeromagnetic and gravity data shows a large scale folded and faulted sequence of prospective Proterozoic basement rocks under some 50m of recent cover. MMI sampling over the Scallywag target was completed in late Q3 2018 at a sample sapcing of 400m x 200m; results have been returned and are reported here.

MMI results from Scallywag display discrete elevated gold, copper, silver and arsenic MMI responses along the western parts of the target area over a strike length of some 6km. Supporting pathfinder elements of cerium, lanthanum, iron, lead and uranium are also coincident along this trend with several clusters of samples displaying a strong multi element response. Highest results returned from MMI sampling were 8ppb silver, 50ppb arsenic, 0.4ppb gold, 480ppb cerium, 2750ppb copper, 33ppm iron, 280ppb lanthanum, 240ppb lead and 335ppb uranium. Response of certain groupings (or suites) of elements over parts of the Scallywag target are similar to those seen in MMI and drill core from the Havieron prospect.

Further interpretation of MMI results from Scallywag will be carried out in conjunction with detailed aeromagnetic and ground gravity data to refine targets prior to drill testing.
