Greatland Gold has announced that multiple pieces of gold have been recovered from
surface in the first few days of field work at its 100% owned Black Hills licence in the
Paterson region of Western Australia.
Further to the announcement of 18 June 2018, field work commenced earlier this week at
the Black Hills licence. The field team commenced work at the Saddle Reefs area collecting
rock chip samples and locating historical access. Their observations reveal the area is
obviously prospective with numerous indications of mineralisation in bedrock. Gossanous
samples have been collected from outcrop and gold nuggets have been found within thin
sand cover at the prospect. Primary gold mineralisation has also been located in bedrock
where gold pieces in rock chip samples are present. These finds are significant considering
the short time field crews have been active at the site. Only 150 metres of strike at Saddle
Reefs has been covered so far and the remaining several hundred metres will be traversed
over the next week. Rock chip samples are being collected and will be analysed with
standard chemical assay techniques, and a further update will be provided in due course.
A photo of recently collected samples, including gold pieces in bedrock and gold nuggets,
from the Black Hills licence can be found under the ‘Black Hills’ section of the Paterson
project page on the Company’s web site at www.greatlandgold.com/paterson/.
The Black Hills gold project covers 25 square kilometres and is located in the Paterson
Region of Western Australia and lies adjacent to the Company’s Havieron licence. Previous
work by companies including Newcrest Limited has outlined several zones of gold
mineralisation in rocks equivalent to those of the large Telfer gold deposit (27m oz) which
lies 30km to the west. Management believes that the gold mineralisation identified to date
on the Black Hills licence may extend into the north western portion of Greatland’s Havieron
Gervaise Heddle, Chief Executive Officer, commented: “We are very pleased by the rapid
discovery and collection of gold from surface within days of the field work commencing.
These early results from Greatland’s first and ongoing exploration campaign at Black Hills far
exceed our initial expectations.
“We are currently reviewing a range of options to accelerate exploration at Black Hills and
we look forward to providing a further update in due course.”
Overview of Paterson Project and Black Hills licence
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 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 (27m oz
gold) and Nifty (2m t copper). 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 Black Hills licence, E45/4512, lies 30 km east of the large Telfer gold mine (27m oz).
Black Hills is a granted exploration licence that covers 25 square kilometres and sits adjacent
to the Company’s Havieron exploration licence. The Black Hills licence is regarded as having
high potential to host gold deposits similar to Telfer. There has been a reasonable amount of
historical exploration work at Black Hills with several discrete zones of mineralisation
identified over 5km of strike. Rock chip samples have returned up to 90g/t gold, and
commonly 20g/t gold, with free (visible) gold in places. Drill intercepts include 3m at 9.14g/t
gold from 26m downhole (incl. 1m at 21.2g/t from 27m (CBR073)), 1m at 10.0g/t gold from
16m (CBH138), 1m at 4.93g/t from 12m (CBH071) and 1m at 3.12g/t from 37m (NBH004).
Historical drill spacing appears quite broad with holes at least 400m apart, some up to 600m.
Gold prospects identified to date extend from Black Hills into the north western parts of the
Havieron licence. Proterozoic sandstone and carbonate rocks of the Yeneena Group
formations are present, including the Telfer Formation, in a domal structure which is the
equivalent geology to that of the large Telfer gold deposit (27m oz) located 30km to the
A large amount of historical surface exploration data for the Black Hills area has been
compiled and merged into the Company’s database. This is the first time all data has been
merged and interrogated with modern technologies. Gold mineralisation has been outlined
at several prospects throughout the licence including Saddle Reefs, Eastern, Rogers and
Northern Granites (within an area of 6.5km x 2km).
Strong surface gold mineralisation is present at the Saddle Reefs prospect with rock chips
including 55.6g/t, 20.0g/t, 19.65g/t, 18.45g/t and 17.0g/t over an area of approximately
1,400m x 800m. The zone has a north-westly trend and sporadic drilling with results
including 3m at 9.14g/t gold from 26m downhole, including 1m at 21.2g/t from 27m, in hole
CBR073. This zone is in the core of an anticlinal feature and, overall, is gold prospective over
a strike length of approximately 3km.
At the Eastern prospect a linear zone of gold mineralised stratigraphy is apparent over a
strike of approximately 4km. Surface rock chip results include 1.9g/t gold, 1.2g/t gold and
1.0g/t gold. Broad spaced drilling along the zone has returned results including 1m at 10.0g/t
gold from 16m (CBH138), 1m a 4.93g/t from 12m (CBH071) and 1m at 3.12g/t from 37m
(NBH004). The mineralisation appears to track along a structural contact and the focus will
be on identifying the higher grade mineralisation along this trend.
The other prospects of Rogers and Northern Granites show prospective gold mineralisation
at surface with rock chip results including 50.2g/t and 10.45g/t at Rogers and 6.9g/t at
Northern Granites. Drill testing is limited but results have included 1m at 1.48g/t from 38m
(NBH008) at Rogers and 1m at 2.35g/t gold from 5m (CBH253) at Northern Granites.
As announced to market on 18 June 2018, the Company commenced field work at Black Hills
early this week. The field team has been initially tasked to work at the Saddle Reefs area
collecting rock chip samples and locating historical access. Productivity so far has been good.
The host sequence of Proterozoic sandstones and limestones outcrop through relatively thin
sand cover and their observations reveal the area is obviously prospective with numerous
indications of mineralisation in bedrock. Gossanous samples have been collected from
outcrop and gold nuggets have been found in thin sand cover at the prospect, along with a
primary source of gold mineralisation in bedrock where gold pieces in rock chip samples are
present. These finds are significant considering the limited time field crews have been active
at the site. Rock chip samples are being collected and will be analysed with standard
chemical assay techniques.
