Greatland Identifies New Drill Targets at Scallywag

 

Geophysical surveys identify four new high-priority targets within the Scallywag prospect in the Paterson region

 

Greatland Gold plc (AIM:GGP), the precious and base metals exploration and development company, is pleased to announce that results from geophysical surveys have outlined several new high-priority targets at its 100% owned Scallywag prospect in the Paterson region of Western Australia.

 

The Scallywag gold-copper prospect area sits within Greatland's Havieron licence (E45/4701), approximately 6km west of the 12 block area under a Farm-in Agreement with Newcrest. Scallywag is an elongate magnetic feature with a strike length of more than 6km. As announced on 15 August 2019, Greatland recently completed an Induced Polarisation ("IP") survey across the northern part of the Scallywag prospect, and an infill ground gravity survey across the entire prospect area. Results from the IP and ground gravity surveys have been received and are reported today.

 

Highlights

 

·     Multiple chargeability responses identified from six IP traverses that were completed over 2km of strike.

·     Several high-priority drill targets identified from a review of IP, gravity and magnetic data:

Kraken: A high intensity 'bulls-eye' magnetic anomaly with the same amplitude, character and depth extent as observed at Havieron. IP results indicate a strong chargeability anomaly coincident with the Kraken magnetic anomaly.

Barbossa: A large 2km by 1km residual gravity anomaly located in a structural corridor 3.5km west of the hinge of the Scallywag dome. Barbossa has semi-coincident gravity and IP chargeability anomalies.

Blackbeard: An elongate 2.6km by 400m ultra-high intensity magnetic anomaly with a coincident moderate amplitude gravity feature. The IP chargeability response at Blackbeard is observed over 800m of strike.

London: Located in a gravity low interpreted to be an intrusive rock within the hinge zone of the Scallywag antiform. The London target IP response is seen over 400m of strike as discrete chargeability anomalies.

·   Greatland expects to drill test these four targets during the next field season and will be conducting additional IP surveys over the southern portion of the Scallywag prospect area at that time.

 

Gervaise Heddle, Chief Executive Officer, commented: "We are very pleased that these results have successfully generated multiple new high-priority drill targets at Scallywag, many of which share similar geophysical characteristics to Havieron. The identification of this first round of high-priority drill targets further reinforces our view regarding the prospectivity of the Scallywag prospect area itself and the Paterson region more generally, a region which we believe could hold multiple tier-one gold-copper deposits. We plan to accelerate drilling of these new targets in the next field season, while also carrying out additional work over Scallywag's southern area to identify further targets."

Overview of Paterson Project

 

The Company's Paterson project comprises the Havieron, Paterson Range East, and Black Hills licences, located in the Paterson region of northern Western Australia. The three licences collectively cover more than 385 square kilometres and are prospective for Telfer style gold-copper deposits, and Havieron style gold-copper mineralisation.

 

In March 2019, Greatland signed a Farm-in Agreement with Newcrest Operations Limited ("Newcrest"), a wholly-owned subsidiary of Newcrest Mining Limited (ASX:NCM), to explore and develop Greatland's Havieron gold-copper project in the Paterson region of Western Australia. Newcrest has the right to acquire up to a 70% interest in a 12-block area within E45/4701 that covers the Havieron target by spending up to US$65m.

 

Greatland's drilling campaigns at Havieron have yielded excellent results to date, including:

·     HAD005:       103m @ 3.5g/t Au and 0.93% Cu from 459m; and

                        128m @ 7.4g/t Au and 0.54% Cu from 660m

·     HAD006:       54m @ 2.7g/t Au and 0.79% Cu from 471m; and

                        179.1m @ 1.4g/t Au and 0.47% Cu from 547.9m

·     HAD008:       67m @ 2.0g/t Au and 0.91% Cu from 426m

 

Recent drilling by Newcrest under the current Farm-in arrangement has returned:

·     HAD012:       43m @ 7.9g/t Au, 0.83% Cu from 900m

·     HAD013:       100.9m @ 2.0g/t Au, 0.48% Cu from 479m

·     HAD014:       244.6m @ 2.0g/t Au, 0.40% Cu from 450m

·     HAD017:       45.0m @ 7.1g/t Au and 0.08% Cu from 1077m

·     HAD018:       96.4m @ 4.5g/t Au and 0.14% Cu from 916.4m

 

The Paterson region is currently one of the most active exploration areas in Australia.  Recent exploration success achieved by Greatland (Havieron) and Rio Tinto (Winu) demonstrates the region has been underexplored, particularly the extensive areas under cover.

 

It is widely recognised that additional gold-copper discoveries in the Paterson will come from areas under cover, and that geophysics is a critical component of the discovery process. For example, Greatland's exploration success at Havieron was largely driven by the application of detailed aeromagnetic and ground gravity geophysical data sets and subsequent modelling.

 

Scallywag Prospect

 

The Scallywag prospect lies approximately 6km west of the Havieron prospect within the Havieron licence. The Scallywag prospect is located within E45/4701 and 100% owned by Greatland.  Limited historic drilling in the immediate area around Scallywag did not intersect basement.

 

Scallywag is a large, elongate magnetic anomaly with a strike length of more than 6km. It is interpreted to be a folded metasedimentary sequence under approximately 50-100m of cover. Geophysical programmes completed to date by Greatland include reprocessing of existing 50m line spaced aeromagnetic data and collection of ground gravity (400m x 200m). MMI sampling over the Scallywag prospect was completed in late Q3 2018 at a sample spacing of 400m x 200m. MMI results from Scallywag displayed discrete elevated gold, copper, silver and arsenic MMI responses along the western parts of the target area over a strike length of approximately 6km. Supporting pathfinder elements of cerium, lanthanum, iron and lead were 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, 280ppb lanthanum and 240ppb lead. Response of certain groupings (or suites) of elements over parts of the Scallywag target are similar to those that were seen in MMI sampling over the Havieron prospect.

 

Ground gravity has recently been completed over the Scallywag area and across the remainder of the Havieron licence E45/4701 (with the exception of the 12 block area within E45/4701 subject to the Farm-in Agreement with Newcrest). Approximately 1,180 gravity stations were collected which have finalised 200m x 200m gravity coverage across the Scallywag prospect itself. This data has better defined basement structures and lithological contacts when combined with detailed aeromagnetic data. From these data sets Scallywag is interpreted to be an antiformal (dome-like) feature of metasedimentary rocks analogous to those at Havieron and Telfer (Lamil Group, Paterson Province). Both magnetic and gravity data have undergone 3D modelling to assist IP survey planning and drill targeting.

 

An IP programme has been completed over the northern third of the Scallywag prospect covering approximately 2km of the 6km of strike. The IP technique can detect disseminated sulphide mineralisation that may be associated with gold-copper mineralisation like that seen at the Havieron prospect. Six IP traverses were completed over 2km of strike. Traverses were between 400m and 800m apart with a minimum line length of 1.6km and maximum of 4.8km. Multiple chargeability responses were identified from the six traverses. 

 

The IP data has been integrated with other data sets such as gravity and magnetics resulting in the identification of multiple targets; magnetic anomalies with IP response, gravity anomalies with IP response, structural targets with IP response and individual IP chargeability targets. From these, four high-priority  targets have been initially selected: Kraken, Barbossa, Blackbeard and London. Details of these targets are outlined below.

 

New Drill Targets within Scallywag Prospect

 

Kraken: A high intensity 'bulls-eye' magnetic anomaly with the same amplitude, character and depth extent as observed at Havieron. Kraken has a structural location in the interpreted hinge of the Scallywag antiform. IP results indicate a strong chargeability anomaly coincident with the Kraken magnetic anomaly.

 

Barbossa: A large 2km by 1km residual gravity anomaly located in a structural corridor 3.5km west of the hinge of the Scallywag dome. Barbossa has semi-coincident gravity and IP chargeability anomalies.

 

Blackbeard: An elongate 2.6km by 400m ultra-high intensity magnetic anomaly with a coincident moderate amplitude gravity feature. The IP chargeability response at Blackbeard is observed over 800m of strike. The chargeability response increases in intensity toward the north.

 

London: Located in a gravity low interpreted to be an intrusive rock within the hinge zone of the Scallywag antiform. The London target IP response is seen over 400m of strike as discrete chargeability anomalies. 

 

Greatland expects to drill test these four targets during the next field season. Concurrent with these drilling activities Greatland will be undertaking additional IP traverses over the southern portion of the Scallywag prospect and drilling will continue to test any further targets generated.

Notes for Editors:

 

Greatland Gold plc is a London Stock Exchange AIM-listed (AIM:GGP) natural resource exploration and development company with a current focus on gold, copper and nickel exploration projects.

 

The Company has six main projects; four situated in Western Australia and two in Tasmania.  All projects are 100% owned by Greatland.

 

In March 2019, Greatland signed a Farm-in Agreement with Newcrest Operations Limited, a wholly-owned subsidiary of Newcrest Mining Limited (ASX:NCM), to explore and develop Greatland's Havieron gold-copper project in the Paterson region of Western Australia. Newcrest has the right to acquire up to a 70% interest in a 12-block area within E45/4701 that covers the Havieron target by spending up to US$65 million.

 

Greatland is seeking to identify large mineral deposits in areas that have not been subject to extensive exploration previously. It is widely recognised that the next generation of large deposits will come from such under-explored areas and Greatland is applying advanced exploration techniques to investigate a number of carefully selected targets within its focused licence portfolio.

 

The Company is also actively investigating a range of new opportunities in precious and strategic metals and will update the market on new opportunities as and when appropriate.

Criteria

Explanation

Commentary

Sampling techniques

•    Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling.

•    Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used.

•    Aspects of the determination of mineralisation that are Material to the Public Report. In cases where 'industry standard' work has been done this would be relatively simple (eg 'reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay'). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information.

Section 2 Reporting of Exploration Results

(Criteria listed in the preceding section also apply to this section.)

 

Criteria

Explanation

 

Mineral tenement and land tenure status

•    Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings.

•    The security of the tenure held at the time of reporting along with any known impediments to obtaining a license to operate in the area.

•    The Scallywag Prospect is located within the following Exploration License:

•    E45/4701 (granted)

•    Twelve (12) blocks of E45/4701 are subject to farm-in by Newcrest Operations Limited (over the Havieron Prospect). 

•    Newcrest Operations Limited holds right of first refusal as per Farm-in Agreement dated 12th March 2019.

•    No known impediments exist, including a license to operate in the area.

Exploration done by other parties

•    Acknowledgment and appraisal of exploration by other parties.

•    Exploration in the region of the Scallywag Project has involved the following companies:

•    The Havieron tenement was first explored in the mid 1980's by Newcrest. The company held the license from 1986 to 1998 and under a Joint Venture with Normandy Exploration ltd from 1998 to 2001.

•    The area was briefly held by Croesus Mining NL in 2001-2002 who carried out an historic data review but no ground work and reverted back to Newcrest from 2003-2009. The area was not worked again until 2013 when Ming Gold undertook an historic data review and remodelling with a view to evaluating preliminary resource potential.

•    The majority of historic work on the Scallywag area was thus carried out by Newcrest who carried out detailed airborne magnetics, radiometrics and DTM, Landsat data; geochemistry; BLEG and soil vapour surveys; drilling; RAB, aircore and RC, which failed to penetrate the Phanerozoic cover. Six diamond drill holes over the Havieron target (~5km east of Scallywag), all of which penetrated the Permian-Proterozoic basement.

•    During 2017 Greatland Pty Ltd undertook detailed ground gravity and MMI surface geochemistry surveys over Scallywag. 

 

Geology

•    Deposit type, geological setting and style of mineralisation.

•    Paterson Province Geological Setting:

•    Proterozoic meta-sedimentary rocks. 

•    Targeted Mineralisation styles include:

•    Iron Oxide Copper Gold (IOCG) and Iron Sulphide Copper and Gold (ISCG). 

•    Intrusive Related (IRG) and Skarn-style gold and copper.

•    Orogenic (vein and reef style) gold;

•    Carlin-style gold.

Drill hole Information

•    A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes:

•    easting and northing of the drill hole collar

•    elevation or RL (Reduced Level - elevation above sea level in metres) of the drill hole collar

•    dip and azimuth of the hole

•    down hole length and interception depth

•    hole length.

•    If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case.

•    No drilling has been completed at this stage of the exploration program.

 

Data aggregation methods

•    In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated.

•    Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail.

•    The assumptions used for any reporting of metal equivalent values should be clearly stated.

•    This release has no reference to previously unreported drill results.

Relationship between mineralisation widths and intercept lengths

•    These relationships are particularly important in the reporting of Exploration Results.

•    If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported.

•    If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg 'down hole length, true width not known').

•    This release has no reference to previously unreported drill results.

Diagrams

•    Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views.

•    This release has no reference to previously unreported drill results.

•    Diagrams including plan maps, perspective and section views are provided with this report.

Balanced reporting

•    Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results.

•    The company believes this announcement is a balanced report, and that all material information has been reported.

 

Other substantive exploration data

•    Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples - size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances.

•    Previous exploration results included in this announcement can be found on the company website: www.greatlandgold.com

 

Further work

•    The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling).

•    Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive.

•    Planned further work includes drill testing of selected target areas.  These targets have been selected based on magnetic, gravity, induced polarization and surface geochemical data.
