Rockfire Resources plc
("Rockfire" or the "Company")
Near-surface gold extended eastwards at Plateau
Rockfire Resources plc (LON: ROCK) the gold and base metal
exploration company, is pleased to announce that Reverse
Circulation ("RC") drilling, which was completed in June 2020, has
extended the footprint of gold mineralisation at the Company's
100%-owned Plateau Gold Deposit ("Plateau"), part of the Lighthouse
tenement in North Queensland, Australia. Mineralisation continues
to adhere to the Mt Wright model in the upper levels of the
mineralising system.
Highlights:
-- Gold mineralisation has been extended another 60 m east of
all previous drilling within the top 200 m from surface. Gold
remains open towards the east and at depth.
-- A shallow, infill drill hole (BPL035) has intersected 82 m @
0.4 g/t Au (from surface). Highlights from this interval
include:
o 6 m @ 2.9 g/t Au (from 59 m), from within:
o 9 m @ 2.2 g/t Au (from 56 m), from within:
o 23 m @ 1.0 g/t Au (from 43 m), from within:
o 40 m @ 0.7 g/t Au (from 25 m)
-- Hole BPL035 also intersected strong silver results including
10 m @ 22.4 g/t Ag (from 55 m), which includes 6 m @ 32.4 g/t Ag (
1.0 oz/t silver ).
-- BPL036 is the most easterly hole drilled so far and has
extended mineralisation another 60 m to the east, demonstrating
that the gold mineralising system remains active at shallow levels.
This hole has intersected 135 m @ 0.2 g/t Au (from 103 m),
including 5 m @ 1.0 g/t Au (from 145 m).
-- Another in-fill hole (BPL037) has returned an extensive
interval of 103 m @ 0.3 g/t Au from 29 m. Highlights from this hole
include:
o 4 m @ 1.0 g/t Au (from 29 m),
o 6 m @ 1.0 g/t Au (from 108 m),
o 4 m @ 1.0 g/t Au (from 129 m),
o 5 m @ 1.5 g/t Au (from 188 m), and
o 4 m @ 1.0 g/t Au (from 234 m)
-- Hole BPL037 also intersected elevated silver results,
including 85 m @ 5.0 g/t Ag (from 28 m) which includes 5 m @ 15.5
g/t Ag (from 108 m) and 5 m @ 12.8 g/t Ag (from 79 m).
-- Zones where visible sulphides above 20% have been observed
during logging of the drill chips have returned the best grades
(e.g. 6 m @ 2.9 g/t Au in Hole BPL035).
-- These results are the last from five shallow in-fill and
extension RC holes drilled in June 2020. A table detailing the
drill collars is provided below.
-- The current diamond drilling programme targeting down to
approx. 500 m vertical depth is still proceeding on time and within
budget, and an update on this exploration will be provided in the
coming weeks.

David Price, Chief Executive Officer of Rockfire commented:
"These infill holes are in line with our expectations for grade
and width in the top 200 m from surface and continue to indicate a
very extensive gold mineralising system at depth. These latest
results extend the mineralised envelope another 60 m to the east,
opening up the opportunity to find more gold at depth towards the
east."
"The silver results indicate that we are in the upper levels of
the mineralising system and form a very important part of the
mineralogical model we are developing. With the price of silver
improving, the silver at Plateau may contribute to the economics as
a by-product, should gold production eventuate."
"These five shallow holes will all contribute to our
mineralisation model which will be used to estimate a resource
upgrade, expected towards the end of the calendar year. In the
meantime, our deeper drilling at levels around 500 m below surface
is continuing both on time and within budget. I look forward to
updating the market of our progress in the coming weeks."

About the Plateau Gold Deposit
The Plateau Gold Deposit is located approximately 50 km
southeast from the gold mining centre of Charters Towers in
Queensland, Australia. Plateau is near two operating gold mines,
the +3 M oz Pajingo Gold Mine (17 km west) and the +10 M oz
Ravenswood/Mt Wright Gold operations (47 km north-east).
Plateau is a breccia/rhyolite hosted gold system, comprising
similar geology and mineralisation to that seen at the nearby Mt
Wright gold mine. Rockfire is targeting a gold system similar to Mt
Wright.
At surface, Plateau hosts gossanous and jasperlitic veins and
gold-bearing breccias. The breccias lie at the margin of a rhyolite
intrusive complex, with gold hosted by veined and brecciated
rhyolite.
