Assay results have been received from two drill holes targeting mineralisation proximal to the Joremeny Adit and two holes targeting mineralisation beneath the Pivo Zone Road cutting.
The drill holes completed proximal to the Joremeny Adit have acted to assist with understanding the structural and lithological setting of mineralisation. Five drill holes specifically targeting the cobalt-nickel sulphide mineralisation within the Joremeny Adit target have been planned. Drilling of these cobalt-nickel sulphide targets proximal to the Joremeny Adit will be commencing in the second week of January.
Channel sampling of mineralised structures parallel to the Pivo Zone has confirmed that multiple zones of mineralisation extends beyond the road cutting and changes in nature to being enriched in silver-copper-antimony.
Lidar survey data has been acquired across Dobsina and has provided a high accuracy digital terrain model (“DTM”). This DTM is utilised for a multitude of purposes including the accurate identification of historical adit entry points, location/extent of historical waste dumps, detailed site based topographic information and infrastructure planning. An interpretation of the location and extents of historical waste dumps has commenced.
Initial 3D modelling of the northern underground adit development across the Zemberg-Terezian Vein system has been completed.
DRILLING OF JOREMENY TARGET
The drilling of the Joremeny Target has further supported the structural and lithological model for targeting mineralisation. The aims of drilling included to determine and refine the structural/lithological model for targeting mineralisation and understand the geometry of mineralisation.
Based on the previous geological mapping and channel sampling completed in 1992, mineralisation within the Joremeny Adit ranges in thickness from 0.3m to 2.5m. The

refurbishment of the Joremeny Adit underway at present will provide significant further understanding with respect to the geometry and extent of mineralisation. In addition, it is proposed that extensive underground drilling is to be completed in conjunction with detailed underground mapping and channel sampling.

PLANNED DRILLING ACROSS JOREMENY ADIT TARGET
Five diamond drill holes have been planned to be completed across the Joremeny Adit, specifically focusing on areas proximal to cobalt-nickel sulphide mineralisation identified in previous underground channel sampling1.
CHANNEL SAMPLING AND DRILLING OF PIVO ZONE
Channel sampling has been completed along strike of the Pivo Zone which has identified multiple mineralised structures. These mineralised structures, occurring along strike from the Pivo Zone are enriched in silver – copper – antimony at surface. This style of mineralisation along strike from the Pivo Zone is typical of what has been previously described in terms of metal zonation with the mineralisation transitioning to cobalt-nickel dominant at depth. Significant results from channel sampling of trenches includes:
