Rumble Resources Ltd. announced that the maiden reconnaissance drilling program at the Braeside Project (E45/2032), located in the Pilbara region of Western Australia, has discovered significant base metal mineralisation indicative of a large porphyry related base metal mineralising system. The discovery of significant high grade zinc mineralisation such as 4m at 9.64% Zn, 0.41% Pb near surface from 32m within a 28 metre wide zone of mineralised alteration at the Devon Cut Prospect in the first ever reconnaissance RC drilling conducted at the Braeside project is outstanding. RC Drilling Programme Summary: The RC drilling programme tested thirteen (13) targets over a strike length of 34km within granted tenement E45/2032. A total of 19 angled RC drill-holes were completed for 2004m. First pass assaying involved both single and composite samples (holes were selectively sampled to expedite assay results - some holes are yet to be sampled). A total of 240 RC chip samples were submitted to Intertek Genalysis Labs in Maddington, Western Australia for multi-element using four acid digestion with ICP-OES and ICP-MS analytical finish. Re-split of composite samples and RC drill holes not yet sampled will be assayed January-February 2018. Targeting of the RC drilling was based on exploration completed by Rumble June-November 2017. Drill targets included: High grade base metal grab sample locations within regional base metal in soil anomalism; Close to or beneath small scale artisanal workings; EM conductors defined by VTEM with ground TEM follow up. RC Drilling Significant Results Summary: Devon Cut Prospect - (single RC drill-hole - BRRC019 - 88m depth). High grade Zn mineralisation: 4m at 9.64% Zn, 0.41% Pb near surface from 32m; High grade zone within broad elevated Zn and Pb alteration (silica-sericite) zone - Altered zone 28m at 1.69% Zn from 28m (0.18% Zn lower cut-off); Mineralisation completely open. Barker Well Prospect - (single RC drill-hole BRRC036 -124m depth). Significant Pb and Zn mineralisation: Very wide alteration down-hole (120m) including silica-sericite-chlorite; Significant and elevated Pb and Zn mineralisation includes - 2m at 3.6% Pb from 6m; Within broad altered andesitic basalt zone of 14m at 0.75% Pb (0.15% Pb lower cut-off); Elevated Pb and Zn associated with alteration includes: 21m at 0.21% Pb from 23m (lower cut-off 0.15% Pb); 24m at 0.13% Zn from 96m (lower cut-off 0.1% Zn). Mineralisation completely open. Cassius Clay Prospect-: Significant Pb and Zn mineralisation: Three RC drill-holes tested high grade surface mineralisation with small workings; Narrow Pb and Zn intercepts include: BRRC009 (depth - 100m) - 1m at 2.55% Zn, 2.68% Pb from 45m; 70m intercept of silica - sericite +/- Kspar +/- hematite alteration. Mineralisation completely open. Ragged Hills North -: Significant Pb and Zn mineralisation: Four RC drill-holes tested high grade base metal surface mineralisation north of the Ragged Hills Historic Pb mine; 600m of strike tested. Narrow Pb and Zn intercepts include: BRRC001 (depth - 158m) - 2m at 3.4% Pb from 25m; 55m intercept of silica +/- sericite +/- Kspar +/- hematite +/- chlorite alteration; BRRC003 (depth - 100m) - 2m at 3.08% Zn, 2.98% Pb from 60m; 40m intercept of silica - sericite - hematite alteration; BRRC006 - (depth - 88m) 3m at 2.19% Zn, 0.95% Pb from 49m; 30m intercept of silica - sericite +/- Kspar +/- hematite alteration; Mineralisation open to north and at depth. Mt Brockman Prospect- (single RC drill-hole BRRC020 71m depth): Significant Pb mineralisation: BRRC020 - 1m at 5.31% Pb from 44m; 55m intercept of silica - sericite +/- hematite +/- chlorite +/- magnetite alteration; Mineralisation completely open. Of the thirteen targets tested, five targets (Devon Cut, Barker Well, Ragged Hills North, Cassius Clay and Mt Brockman) returned significant base metal mineralisation (Devon Cut returned high-grade Zn mineralisation). A further 4 targets (RC Drill-holes - BRRC008, BRRC021, BRRC022 and BRRC037) returned elevated Zn and Pb (>1000ppm Zn and Pb).
