Drilling hits high-grade gold under Plateau resource

Rockfire Resources plc (LON: ROCK), the gold and base-metal explorer, is pleased to announce that high-grade gold has been intersected in the final two drill holes to test beneath the gold resource at the Company's 100%-owned Plateau Gold Deposit in Queensland, Australia.

-- 1 m @ 18.4 g/t Au in drill hole BPL012 is the second-highest gold grade encountered in drilling at Plateau;

   --    12 m @ 2.5 g/t Au, including 5 m @ 4.8 g/t Au (from 61 m), in hole BPL012; 
   --    10 m @ 2.0 g/t Au, including 4 m @ 4.2 g/t Au (from 65 m), in hole BPL019; 
   --    Further geophysics is planned to extend the survey completed in November 2019; 

-- These intersections extend the mineralisation at depth and are expected to expand the current resource estimate of 41,000 ounces of gold;

-- All drill holes in the October 2019 drilling program hit potentially economic gold grades and potentially mineable widths;

   --    Modelling of mineralisation will be updated to include results from recent drilling; 

-- Additional reverse circulation (RC) drilling is planned to extend gold mineralisation along strike and at depth.

Please refer to the following link to view the drill hole locations.

David Price, Chief Executive Officer of Rockfire, commented:

"We're delighted that drilling beneath the Plateau resource has hit such excellent grades and widths. These results demonstrate that gold mineralisation extends deeper and provides strong growth potential for the resource."

"These deeper intersections are only 65m from surface and are still well within depths possible for open pit mining. There are operating gold processing plants nearby, so should any future toll treatment possibility eventuate, the costs of processing may materially reduce. I should clarify that no discussions have been instigated with the owners of these facilities at this point in time."

"With all holes in this drilling campaign intersecting outstanding gold grades and widths, we are confident that our understanding of the geology and mineralisation is improving with each hole drilled. Additional geophysics will be undertaken to expand our interpretation at depth."

"Targets for growth of the gold resource have been clearly identified and Rockfire plans to recommence drilling as soon as possible. The recent exercise of warrants has provided additional drilling capital and our technical team has already started planning for the next phase of drilling."

About the Plateau Gold Deposit

The Plateau Gold Deposit is located in Queensland Australia, approximately 50 km southeast from the gold mining centre of Charters Towers. Plateau lies 17 km east of the operating Pajingo Gold Mine (+ 3 M oz Au), and 47 km southwest of the +10 M oz Au Ravenswood gold mining operations, including Mt Wright. Plateau is a breccia-hosted gold system, comprising similar geology and mineralisation to that seen at the nearby gold mines, Mt Wright and Kidston. Rockfire is targeting another Mt Wright-style and size of deposit.

At surface, Plateau hosts gossanous and jasperlitic veins and gold-bearing breccia at the margin of a felsic (rhyolite) plug. The deposit is under-explored but historical drilling has returned intervals of high-grade gold from a distinct circular magnetic feature. This feature is partly demagnetised and truncated by a linear northeast fault with associated polymict breccia, gossan and chalcedonic and jasperoidal silica flooding.

Previous drilling campaigns have intersected encouraging drilling intersections including 89 m @ 1.57 g/t Au from 61 m (hole PL102), 11 m @ 2.0 g/t Au from 44 m (hole PLP127) and 22 m @ 1.9 g/t Au from 39 m (BPL002).

A single, deep diamond hole drilled by Newcrest Mining in 2007 intersected 300 m @ 2.2 g/t Ag (hole PLDD06001), which highlights the potential size of the mineralised system at depth. This hole provides clear evidence that a large mineralised gold +/-silver system exists deeper below current drilling levels.

Plateau Exploration History

In 1985, Esso Australia Ltd drilled 876 m of core drilling (in 3 holes), 350 m of percussion drilling (in 4 holes) and 126 m of pre-collar drilling for a total of 1,352 m. Impressive drilling results were encountered close to surface, including: 3 m @ 4.87 g/t Au, 3 m @ 3.38 g/t Au, 89 m @ 1.57 g/t Au, 5 m @ 2.77 g/t Au, and 40 m @ 1.37 g/t Au. A total of 1,260 m of trenching was undertaken during the 1985 field season with results including 40 m @ 1.37 g/t Au (Trench 3700 E). Esso also sampled the surface rocks at Plateau, which returned a 116 g/t Au assay.

In 1988, City Resources Ltd drilled 30 reverse circulation drill holes for 1,670 m at Plateau. Values up to 16 g/t Au were intersected in drilling which tested gold mineralisation down to 60 m vertical depth. Best results from this drilling include: 8 m @ 3.03 g/t Au, 10 m @ 5.01 g/t Au, 14 m @ 2.44 g/t Au, 6 m @ 3.20 g/t Au, and 4 m @ 4.79 g/t Au.

In 2007, Newcrest Mining Limited drilled a single 853.7 m deep diamond drill hole (PLDD06001). This hole was designed to test mineralization at depth beneath the shallow mineralisation at Plateau. PLDD06001 intersected 300 m @ 2.2 g/t Ag but only low-grade gold. The drill hole intersected breccia between 150 m and 520 m below surface, confirming that the breccia is much larger than the surface expression suggests. This hole is now thought to have intersected the very edge of the projected mineralised lode, but likely too far to the west to encounter significant gold. A second hole was planned by Newcrest further to the east but this hole was never drilled.

In late 2017, Rockfire Resources plc drilled 11 drill holes for 2,111 m of reverse circulation drilling. This drilling successfully encountered 10 m @ 1.9 g/t Au, 22 m @ 1.86 g/t Au and 10 m @ 1.37 g/t Au. Significant silver was also encountered including 43 m @ 4 g/t Ag.
