Scallywag Exploration Results

 

Prospectivity of targets confirmed

Significant gold and multi-element geochemical anomalism detected

High-grade silver and copper mineralisation intersected

 

 

THIS ANNOUNCEMENT CONTAINS INSIDE INFORMATION AS STIPULATED UNDER THE UK
MARKET ABUSE REGULATIONS.  ON PUBLICATION OF THIS ANNOUNCEMENT VIA A
REGULATORY INFORMATION SERVICE, THIS INFORMATION IS CONSIDERED TO BE IN THE
PUBLIC DOMAIN.

Greatland Gold plc (AIM:GGP; Greatland or Company) is pleased to announce the
results of its 2022 exploration programme at its 100%-owned Scallywag project
in the Paterson region of Western Australia.  Scallywag is located adjacent
to Greatland's flagship Havieron gold-copper project which the Company
discovered in 2018.

Highlights

§ Hole A35RD001 targeting the A35 Prospect conductor intersected 2m @ 2.04g/t
Au from 70m, within a mineralised gold halo of 12m @ 0.48g/t Au from 69m
noting that the interval contains wet samples and immediately precedes a
missing sample.  Significantly, anomalous bismuth and other pathfinder
geochemistry is associated with the intersection

§ Anomalous gold, strong silver and copper plus pathfinders identified while
testing a conductor at the Pearl prospect (PPDD003) include:

-   1m @ 1,364g/t Ag and 0.35% Cu from 76m (remains open at depth)

-   1m @ 0.76g/t Au and 109ppm Bi from 251m

-   1m @ 0.1% Cu and 22.6ppm Bi from 418m

-   1m @ 50.9ppm Bi from 65m

§ These results came as a result of a ground electromagnetic (EM) survey
(follow up on the 2021 programme) which confirmed and refined several EM
conductor targets, testing of which commenced with reverse circulation (RC)
pre-collar and diamond core drilling

 

Greatland Managing Director, Shaun Day, commented:

"Our recent exploration campaign at Scallywag has delivered the most
encouraging results to date."

"At the A35 Prospect, pre-collar drilling was completed with gold
mineralisation intercepted plus important pathfinder geochemistry encountered,
including bismuth which is associated with the Havieron and Telfer gold-copper
deposits.  The high-grade silver and copper mineralisation intercepted at the
Pearl Prospect, confirms the possibility of a new style of deposit being
identified. The underlying deeper geophysical targets at both prospects are
yet to be tested but have now been prioritised for diamond drilling in 2023."

"These results, together with the continual improvement in understanding of
the buried geology, stratigraphy and structure, increase our confidence in the
prospectivity of the ground, and our ability to vector towards intrusion
related and other styles of mineralised systems at Scallywag."

Overview of the 2022 Scallywag Programme.

Exploration work in 2022 focused on drill testing prospects and anomalies
defined from previous ground EM and drilling programmes (see RNS Announcement
titled "Results from the 2021 Exploration Programme at Scallywag" dated 5
April 2022).

A specialised RC rig was used to drill pre-collars ahead of completing the
holes with a diamond rig with the aim of improving result turnarounds.  A
total of eight RC pre-collar holes for 1,238m and one diamond hole with a
total depth of 488.6m, for a total of 1,726.6m, were completed (see Table 1
and Figure 1 below).

Figure 1. Ground EM, Drilling and targets

 

The approach to drilling was influenced by unexpectedly high water inflows in
some areas, limiting the achievable depth of the pre-collars.  The diamond
rig became available late in the field season after completing other
priorities, resulting in only one hole (PDD003) completed at Scallywag.
Completion of the remainder of the RC pre-collars with diamond tails is
planned for 2023 as is follow up drilling based on the latest results.

Pearl Prospect

Following ground EM geophysical surveys, refined EM conductor targets were
generated at the Pearl prospect during the start of the field season.  In
addition to drilling two RC pre-collars to test the plate targets defined
during 2021, an additional hole was diamond drilled from surface (being
PDD003) targeting a newly identified high priority EM conductor.

Drilling intersected fine-grained, silty sandstone sediments with zones of
variably intense calcareous sandstones.  A zone of high water inflow and
extremely broken ground, thought to be a major fault or shear structure, was
intersected.   No sample was able to be collected between 77m and 151m
downhole, as a mud-rotary method was required to advance the hole due to
challenging ground conditions.

Several small metallic chips with native copper and chalcopyrite were
collected from the rubbly core at around 76 - 77m, immediately before the area
of maximum broken ground and no sample returned.  Initial portable X-ray
fluorescence (PXRF) analysis showed readings up to 17% copper, with highly
anomalous silver and tungsten. Any interpretation as to the origin and nature
of these metallic fragments would be highly speculative given the nature of
the sampling.

Subsequent laboratory assays revealed multiple instances of anomalous precious
and base metals (see Table 2 and Figure 2) including:

§ 1m @ 1,364g/t Ag and 0.36% Cu from 76m

§ 1m @ 0.76g/t Au with a 109ppm Bi from 251m

§ 1m @ 0.11% Cu from 418m

§ 1m @ 50.9ppm Bi from 65m

Table 2. Significant assays from Scallywag drilling

 

Interestingly, the high copper-silver assay interval comes from the final
recovered sample before drilling conditions forced mud-rotary drilling.  The
poor drilling conditions are likely due to a significant structure being
intersected in the hole. From the assay results at the top of the structure it
is likely that this large structure is mineralised. Mineralised shear zones
are hosts to many ore bodies in Australia and globally. Greatland is intending
to re-drill at least part of the unsampled hole interval during its 2023
program.  This will enable the Company to complete the geological picture and
more fully understand the highly encouraging metal values in the PXRF reading
and lab assays.

A35 Prospect

At the A35 Prospect, three RC pre-collars were drilled to target the deep
interpreted EM conductor plates.  Assay results for A35RD001 returned a
significant gold intersection of 12m @ 0.48g/t Au from 69m, including 2m @
2.04g/t Au from 70m, in the weathered profile, with associated geochemical
pathfinder element anomalism (see Table 2).  It must be noted that the hole
was also affected by water inflows and the majority of samples from the
mineralised zone from around 68m to 86m downhole were wet or moist and there
was potentially downhole smearing of the high gold grades.  No sample was
able to be recovered from the 72 - 73m interval.

The results are highly encouraging as the gold and base metal anomalism may
represent a supergene enrichment of primary mineralisation at depth,
potentially around the untested EM plate target, and the water inflows may
indicate a significant geological structure, also promising for transporting
and focusing gold-copper mineralising fluids.  Completion of the diamond core
tails and testing of the EM plate is a priority for the 2023 programme.

 

 

Ground EM Surveying

Detailed 1D and 2D re-processing of high priority zones within the aerial
electromagnetic datasets was completed as part of the 2022 work programme.
An additional Ground Electro-Magnetic (GEM) survey was completed over the
Pearl and A35 targets to better define the geometry and location of the
interpreted bedrock conductors, prior to drilling.  Approximately 20-line
kilometres of fixed loop GEM data were collected, over the Pearl and A35
target areas (see Figure 1).

Soil Sampling

A total of 339 soil samples were collected over the western part of the
Scallywag licence (see Figure 3).  Samples were collected mainly 100m apart,
up to 200m in places, on 300 - 800m spaced, east south east orientated,
available cleared tracks.  This work was designed to test the efficacy of the
Ultra Fine Fraction analysis method which is considered useful in areas of
sandy, thicker cover.  Results were low in tenor and inconclusive given the
small sample.  Further surface sampling options are being evaluated given the
relatively modest cover known in the north western part of the tenement.

Next Steps

The 2023 exploration programme at Scallywag is designed to complete the
testing of the mineralisation at the Pearl and A35 prospects as well as the
previously defined GEM conductors at the Swan, A35 and A34 prospects with
diamond core tails to the RC pre-collars

Infill and extensional surface geochemistry in suitable areas which follows up
results from the 2022 Ultra Fine Fraction geochemistry programme will also be
completed.

About Greatland

Greatland is a mining development and exploration company focused primarily on
precious and base metals.

The Company's flagship asset is the world-class Havieron gold-copper project
in the Paterson region of Western Australia, discovered by Greatland and
presently under development in joint venture with ASX gold major, Newcrest
Mining Limited.

Havieron is located approximately 45km east of Newcrest's existing Telfer gold
mine. The box cut and decline the Havieron orebody commenced in February 2021.
 Development continues to accelerate with record advancement achieved in the
December 2022 quarter.  Havieron is intended to leverage the existing Telfer
infrastructure and processing plant. Access to Telfer will de-risk the
development, reduces capital expenditure and lowers the project's carbon
footprint.

Greatland has a proven track record of discovery and exploration success and
is pursuing the next generation of tier-one mineral deposits by applying
advanced exploration techniques in under-explored regions.  Greatland has a
number of exploration projects across Western Australia and in parallel to the
development of Havieron is focused on becoming a multi-commodity miner of
significant scale.
