Rumble Resources provides update on the RC drill program
Friday, May 04, 2018
Rumble Resources Ltd is pleased to provide an update on the scheduled RC drill program at the Nemesis Gold Project (M20/33) which is located 40km's north of Cue in the Murchison Goldfields of Western Australia. Subject to approvals and subsequent drill site preparations, it is anticipated drilling at the Nemesis Gold Project will commence mid May 2018.

Highlights

Nemesis High Grade Gold Project - M20/33

- RC drill holes will be targeting the depth extensions of the historic Nemesis Au mine for potential high-grade mineralisation.

o Between 1900-1910, the Nemesis gold mine produced 7157oz of gold from 2276 ton of ore - 98 g/t Au grade

o No drilling has tested the depth extension to the Nemesis mine workings.

- RC drill holes are planned to test areas of historic elevated Au in soil anomalism west and east of the Nemesis Au mine within the Nemesis Shear Zone.

o The Nemesis Shear Zone extends under a laterite plateau to the east and has not been drill tested. Strong Au in soil anomalism has not been drilled tested to the west.

Nemesis Shear Zone

The Nemesis shear zone is an east-west trending mineralised shear zone that forms the contact between the north sequence of mafic volcanics/BIF's and granites to the south. The shear zone occurs close to the scarp of the lateritic plateau.

The mineralisation style associated with the Nemesis Shear Zone (NSZ) is high-grade gold with quartz veining in high sulphidation (pyrrhotite/pyrite) zones in contact with BIF/mafic volcanics and granites. The NSZ is steeply dipping to the north. Sub-vertical shoots (i.e. the Nemesis mine) have generally short strike lengths with significant dip length extensions.

The Nemesis Shear Zone strikes approximately over 1.2 km within the project area and the Nemesis mine area has only been partly tested by shallow RC drilling over a strike of 160m.

Gold in soil anomalism (lag sampling) with >50 ppb Au response extends along the NSZ. Over 500m of strike remains untested by drilling including where the NSZ extends under the laterite plateau.

Nemesis Shear Zone High-Grade Gold Drill Targets

Nemesis Mine - Depth Extension


The historic workings at the Nemesis Au mine have been worked to a maximum depth of 70m with three steep plunging high-grade gold (average grade of 98 g/t Au) shoots (85deg to the east) over a strike length of 60m. The shoots are stacked and the plunge of the stacking is moderate to the east.

RC drilling along strike to the east was very shallow (maximum vertical depth of 35m) and did not test the plunging mineralisation.

Rumble plans to complete up to 3 RC drill holes targeting high-grade gold mineralisation below the current Nemesis ore shoots.

Nemesis Shear Zone Strike Extension Targeting

Rumble plans to RC drill test for potential high-grade shoots associated with the Nemesis Shear Zone along strike from the Nemesis Au Mine. Targets are east and west from the Nemesis Au Mine. The western target (500m west of the Nemesis Au Mine) lies immediately below the laterite scarp and is related to Au in soil anomalism over the Nemesis Shear Zone. The eastern target (some 300m easterly of the Nemesis Au Mine) is where the Nemesis Shear Zone is interpreted to pass under the laterite plateau. Au in soil anomalism occurs over the laterite and has not been drill tested.

About the Historic Nemesis Gold Mine

The historic production of the Nemesis gold mine was in two stages. Refer ASX announcement 6 March 2018 for further detail including open file reference.

- Mining started in 1900 and 5,538.86 oz of gold was produced from 2,075 tonnes for 83 g/t Au.

- In 1909, another 1618.14 oz of gold was produced from 201 tonnes for 250 g/t Au.

- The total production is 7157 oz of gold from 2,276 tons for an average weighted grade of 98 g/t.
