Mother Lode is a privately owned and registered Australian company. The company has 4 exploration permits which are in the historical gold and copper fields of Queensland, with a further 1 application pending.
EPM 25342 TEN MILE CK (Granted 2014)
The permit lies 150km NW of Cairns within the headwaters of the Palmer River, the richest historic alluvial goldfield in Queensland. Since granted, exploration by Mother Lode for hard rock sources has culminated in the discovery of an ore-shoot within the 400m long Munukurru Quartz Reef. The style of gold mineralisation at Munukurru is orogenic with bonanza gold grades in rock chips assaying 3,187.0 g/t Au, 85.7 g/t Au and 66.7 g/t Au.
EPM 25987 WHITE’S CK (Granted 2016)
The permit lies some 7km SW of Ten Mile Ck EPM 25342. Orogenic style Au-As mineralisation occurs in quartz veins, stockworks and breccias all within a distinctive 5km long x <300m wide belt of quartz arenite. Rock chip sampling at the Nganjirr prospect within the arenite unit has returned assays up to 8.56 g/t Au and 16.2 g/t Au.
EPM 25970 DRY RIVER (Granted 2015), EMP 27304 BELLEVUE COPPER (Application)
These EPMs cover the OK Copper Mining district 70km NNW of Chillagoe, Queensland. VMS style Cu-Zn-Au mineralisation, seen as gossan bands on the surface, occurs in steeply dipping lenses within the favourable OK Member stratigraphy. It has over 15km strike length from Hobblechain Creek prospect in the north to the old OK South mine near the southern boundary of EPM 25970. 10 separate prospect areas have been identified and scout drill targets have been proposed to test the combined 1.8km gossan lens exposures mapped to date. Outcrop rock chip sampling by Mother Lode has returned assays of;
· 11.4 g/t Au at Hobblechain Creek prospect
· 19.4 g/t Au and 14.5% Cu from Windmill Creek prospect
· 19.1% Cu from the closed mine at Hamill
· 5.2% Cu from old closed OK South mine
· 6.2% Cu from old closed OK North mine
Best immediate resource potential occurs at OK North where over 1,100m of gossan bands (1-5 m wide) have been mapped in 2-3 parallel lenses within an 850m segment of the 100m wide receptive OK Mine Sequence stratigraphy. This zone coincides with known strong IP anomalism from earlier geophysical surveys. Limited historic drilling at OK North has confirmed the VMS lenses persist to over 430m depth below the surface with a best intercept of 9m @ 4.2% Cu, 2.6% Zn and 1.49 g/t Au from 160-169m downhole.
EPM 27089 DIMBULAH COPPER (Granted 2019)
The Exploration Permit Application covers all mineralisation and old workings associated with the Dimbulah porphyry copper prospect located 11km WSW of Dimbulah town. Previous explorers attracted to this porphyry copper deposit (including Anglo American, BP Minerals and CRA Exploration) conducted approximately 2,800m of drilling in 50 shallow holes between 1972 and 1993. A pre-JORC resource estimate of 20 million tonnes grading 0.25% Cu has been previously reported. Best copper intersections (including 9.1m @ 0.62% Cu from 160.6-169.7m depth in hole DMB1 and 21m @ 0.75% Cu from 9.0-30m depth in hole RC91PH16) are associated with zones of silicification and elevated As geochemistry. The presence of silica-alunite alteration capping surrounding mountains suggests the current level of erosion is just below the base of a once extensive porphyry lithocap.
