Tribune Resources (ASX: TBR) has provided an update of drilling at its Adiembra prospect, in the Japa gold project in Ghana.
The Reverse Circulation and Diamond Core drilling program at the Japa Project which commenced in December 2019 continued throughout the March Quarter. The drilling program was designed to more clearly define mineralisation within the Adiembra prospect through infill drilling and testing both lateral and depth extensions to the system, ultimately enabling a Mineral Resource estimation to be prepared.
Gold mineralisation at Adiembra is hosted by narrow quartz and quartz-pyrite veins which crosscut a sequence of shale, siltstone, sandstone and phyllite in a regular orientation almost normal to the strike of the rock package.
Drilling by Tribune to date has defined mineralisation within a very broad system over 1400 metres long, up to 700 metres wide and to a maximum depth of 255 metres below surface. Within this large system, mineralisation is concentrated within two distinct lodes, Adiembra West and Adiembra Central. Adiembra West has a strike length of over 1250 metres and ranges from 40 to 80 metres in width whilst Adiembra Central has a strike length of over 1400 metres and ranges from 60 to 180 metres in width. Both lodes are open along strike and at depth.
During the March Quarter a total of 22,441 metres were drilled in 127 holes including 4,924 metres of diamond core and 17,517 metres of RC percussion. Details of these holes are presented in Table 2. The program to date has confirmed the orientation and tenor of mineralisation defined by previous drilling campaigns and has enhanced the understanding of the structural controls on gold distribution through the Adiembra deposit.
