Latest Drilling Results at Havieron Highlight Potential Bulk Tonnage Target

On track to deliver initial resource at Havieron in Q4 2020 as footprint of mineralisation is extended with the expansion of a new mineralised breccia zone

Greatland Gold plc (AIM:GGP), the precious and base metals exploration and development company, is pleased to provide an update on Newcrest's drilling campaign at Greatland's Havieron deposit in the Paterson region of Western Australia.

The new breccia zone ("Northern Breccia"), identified in step out drilling in the north west part of the Havieron deposit, continues to expand with further drilling. Currently, the Northern Breccia has a footprint of ~300m x 100m x 300m open at depth and highlights a broad bulk tonnage target.

Greatland notes the release of an ASX announcement titled "Exploration Update" by Newcrest Mining Ltd ("Newcrest") earlier today.

Highlights

·      Further excellent results from the Northern Breccia highlight the potential for a broad bulk tonnage target at Havieron.

·      Importantly, higher grade zones related to massive sulphide mineralisation are also observed within the Northern Breccia.

·      Infill drilling results continue to demonstrate geological and grade continuity within the high-grade crescent sulphide zone and surrounding breccia.

·      Latest drill results provide additional support to the ongoing investigation of both high-grade selective and bulk mining methods.

·      These results further advance the geological understanding of the system and indicate further potential for additional breccia and higher-grade sulphide style mineralisation in the less explored Northern Breccia region.

Next Steps

·    On track to deliver an initial resource for Havieron in calendar Q4 2020.

·    Exploration programmes at Havieron continue, with both infill drilling to deliver a resource and step out drilling to define the extent of the mineralised system.

·    Environmental and baseline studies progressing to support potential commencement of decline at Havieron by end of calendar year 2020 or early 2021, subject to market and operating conditions and receipt of all necessary permits, consents and approvals.

·    Continuing to investigate potential to achieve commercial production within two to three years from commencement of decline.

Gervaise Heddle, Chief Executive Officer of Greatland Gold plc, commented: "The expansion of the new Northern Breccia zone is an important development that highlights the potential for a bulk tonnage mining operation at Havieron. Significantly, excellent results from step out drilling to date indicate the presence of higher-grade, massive sulphide mineralisation within the breccia bodies, which are yet to be fully defined by drilling and remain open at depth.

"As Newcrest's ongoing exploration programmes continue to define the extent of the mineralised system, we are also pleased to confirm the expected delivery of an initial resource at Havieron in Q4 2020. Alongside the progress at Havieron, we are continuing with our exploration plans at our other assets in the Paterson region and look forward to providing the market with further updates."

Analytical results for HAD031W1, HAD043W2, HAD047, HAD048, HAD055W1, HAD065, HAD068W2, HAD069, HAD070, HAD072, HAD073, HAD074, HAD075, HAD076, HAD077, HAD078, HAD079, HAD080, HAD081, HAD082 have been received and are announced today. Selected significant intercepts are presented in Table 1.

Further Information on Newcrest Drilling and Operations at Havieron

Exploration activities at Havieron are operated by Newcrest under a Farm-in Agreement with Greatland. The Havieron deposit is centered on a magnetic anomaly located 45km east of Telfer. Exploration drilling by Greatland during 2018 resulted in the discovery of significant gold and copper mineralisation under 400m of post mineral cover. Newcrest commenced drilling at Havieron during the June 2019 quarter.

A further 22,155m of new drilling has been completed since 30 June 2020 for a total of 98,698m of drilling by Newcrest. Results reported today are from a further 20 holes including wedges. Significant results are presented in Table 1. Infill and step out drilling results announced today are considered excellent.

At Havieron, exploration programs have focused on an infill drilling program to deliver an initial resource, and step out drilling to define the extent of the Havieron mineralised system. Additional drilling results since the 30 June 2020 Quarterly Exploration Report have validated the expanded extent of the Havieron mineralised system and drilling continues to define the new "Northern Breccia" mineralised zone.

Overall, the step out drilling has defined a 650m x 350m NW trending ovoid shaped variably mineralised breccia. On the margins of the breccia is a higher grade sulphide zone.

The new breccia zone, the "Northern Breccia", identified in step out drilling in the north west continues to expand with further drilling. Currently the Northern Breccia has a footprint of ~300m x 100m x 300m open at depth and highlights a broad bulk tonnage target. Importantly internal higher grade zones related to massive sulphide mineralisation are also observed within this breccia. These results further advance the geological understanding of the system and indicate further potential for both additional breccia and higher grade sulphide style mineralisation in this less explored region. 

Infill drilling in the south-east continues to demonstrate geological and grade continuity over the upper 600m vertical extent of the high grade crescent sulphide zone and surrounding breccia with infill hole HAD077 returning 127.6m @ 2.0g/t Au, 0.33% Cu from 551m including 29.8m @ 6.7g/t Au, 0.86% Cu from 616m. Ongoing infill drilling is nearing completion, focused on the delivery of an initial resource in calendar Q4 2020.

The high grade sulphide zone forms an ovate shape with a south-eastern and north-western closure. The mineralisation is best developed in the south-eastern closure.

·    In the south-eastern closure:

·    The upper levels of the system (-170m to -400mRL) have an internal unfolded strike of 550m, an average width estimate of 20m and a height of 230m.

·    The mid level of the system (-400m to -600mRL) has an internal unfolded strike of 400m, an average width estimate of 20m and a height of 200m.

·    The lower levels (-600m to -800mRL) where drill tested, has the crescent zone which tapers in strike length to 200m, with a width of approximately 20m and a height of 200m.

·    Breccia mineralisation adjoining the Crescent zone continues to deliver strong results including HAD077.

·    In the north-western closure:

·    Initial drill testing indicates the sulphide zone mineralisation is thinner and irregular (typically averages <5m, with rare 10m intercepts).

·    At this early stage additional drill testing is required to determine ore shoot distribution.

·    Mineralisation on the limbs between the south-east and north-west closure is irregularly developed.

Infill drilling of the south-east arcuate sulphide Crescent zone (with nominal drill spacing of 50 - 100m laterally, and 100m vertically) is nearing completion to support the delivery of an initial resource in Q4 2020.

Ongoing extensional drilling has confirmed and further expanded the footprint of the northern breccia hosted mineralisation. Previously reported drill holes HAD066 and HAD046W1 intersected a new breccia zone returning 128.7m^^ @ 1.0g/t Au and 0.13% Cu from 734.1m (HAD066) and 134.6m^^ @ 2.5g/t Au and 0.07% Cu from 923m (HAD046W1). Importantly hole HAD046W1 internal to this interval returned a higher grade zone including 27.3m^^ @ 10g/t Au and 0.13% Cu from 944.7m associated with more intense sulphide development. Drilling in the reporting period has continued to define this mineralised northern breccia zone. Additional results during the reporting period include HAD047, 309m @ 0.99g/t Au, 0.07% Cu from 915m including 44m @ 3.3g/t Au, 0.15% Cu from 1157m and HAD078, 208.6m @ 1.2g/t Au, 0.22% Cu from 832.4m including 10.4m @ 4.0g/t Au & 0.11% Cu from 1002.6m.

^^ previously reported 11 June 2020

Mineralisation at the Havieron deposit remains open to the north-west, has been observed to over 1,000m below post mineral cover, and remains open at depth. The extents of the Havieron system are still to be defined.

Ongoing drilling will be supported by surface exploration activities including ground and airborne geophysics. A 31 line kilometre seismic survey has recently been completed to de-risk development activities and provide a better understanding of the regional geological and mine scale structural setting.  Acquisition of SKYTEM over the JV Blocks is being considered.

Studies are ongoing and include mining methods, hydrogeology, geotechnical, metallurgical, engineering and environmental to support delivery of a mineral resource estimate in Q4 2020.

Newcrest continues to investigate the potential to commence an exploration decline at Havieron by the end of calendar year 2020 or early 2021, subject to market and operating conditions and receipt of all necessary permits, consents and approvals, along with the potential to achieve commercial production within two to three years from commencement of decline.

Newcrest has implemented and maintained measures to reduce and mitigate the risk of the COVID-19 pandemic to its project workforce and key stakeholders. Potential impacts of the COVID-19 pandemic on the drilling activity at Havieron are being actively managed and considered as part of the studies underway. There have been no COVID-19 cases at Havieron.

Stage 3 of the Farm-in is progressing including ongoing exploration drilling and studies to support early development options. Currently, nine drill rigs remain operational. A 100 person camp is on-site to support ongoing operations. In order to complete Stage 3 of the Farm-in Agreement, Newcrest must spend an additional US$25 million and deliver a Pre-Feasibility study for the Havieron project.

Additional drill hole information is presented in Appendix I and tabulated drill hole intercepts are presented in Appendix II.

Deposit mineralisation is hosted by metasedimentary (meta-sandstones, meta-siltstones and meta-carbonate) and intrusive rocks. Gold and copper mineralisation is hosted in breccia, vein and massive sulphide replacement styles, typical of intrusion-related and skarn types of mineralisation. The main sulphide mineral assemblage contains well developed pyrrhotite-chalcopyrite and pyrite. Alteration assemblages associated with mineralisation are amphibole-carbonate-biotite-sericite-chlorite. Higher grade gold zones (+10g/t Au) are often associated with quartz/chalcopyrite-pyrite veining.

Background to Havieron and Farm-in Agreement with Newcrest

In March 2019, Greatland entered into 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 discovery in the Paterson region of Western Australia. Newcrest has the right to earn up to a 70% interest in a 12-block area within E45/4701 that covers the Havieron target by spending up to US$65m. Newcrest may acquire an additional 5% interest at the end of the Farm-in period at fair market value.

Newcrest has completed Stage 2 of the Farm-in Agreement. In accordance with the terms of the Agreement, Newcrest has earned a 40% interest in the Havieron Project. Newcrest is now progressing Stage 3 work programs including ongoing exploration drilling and studies to support early development options. In order to complete Stage 3 of the Farm-in, Newcrest must incur an additional US$25 million in expenditure and deliver a Pre-Feasibility study for the Havieron Project. If Newcrest successfully completes Stage 3, Newcrest will earn an additional 20% Farm-in Interest (cumulative 60% Farm-in interest).

During the Farm-in and Havieron Joint Venture periods, Newcrest will have a right of first refusal over the remainder of the Havieron licence. During the Farm-In period, Newcrest will have a right of first refusal over Greatland's Black Hills and Paterson Range East licences.

The Farm-in Agreement includes tolling principles reflecting the intention of the parties that, subject to a successful exploration programme and feasibility study, the resulting joint venture ore will be processed at Telfer, located 45km west of Havieron.

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 precious and base metals. The Company has six main projects; four situated in Western Australia and two in Tasmania.

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 deposit in the Paterson region of Western Australia. Newcrest has the right to earn 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.
