The A12 Prospect lies on the Jugan - Sirenggok mineralisation trend approximately 1 km WSW of Jugan, where it appears to have been dextrally displaced by 250 - 350m across northwest oriented cross-fault tend. This cross-fault trend forms the current known boundary for Jugan Deposit mineralisation in that direction. Fault displacements are known to post-date mineralisation, and A12 may represent a fault displaced continuation of an originally more extensive zone of Jugan mineralisation.
The A12 Prospect will be drilled for the first time in the Company's upcoming drilling program scheduled to commence imminently. Conceptually, the extension of mineralisation to the southwest beyond the Jugan Deposit is supported by the A12 Prospect exhibiting similar, but not identical, geological and geophysical anomaly signatures.
Importantly, differences between the signatures suggest that A12 may be even more prospective than Jugan because: The modelled EM anomaly of A12 is volumetrically significantly larger than the equivalent coincident with the Jugan Deposit.
Surface outcrops at A12 include silica rich lithologies, including jasperoid floats, suggesting local exposure to silicia rich fluid alteration making the
A12 appears to have been subjected to more extensive epithermal alteration.
Geological mapping (altered silica-rich float outcrops), geochemical surveys (soil Au, As and Hychip) and geophysical surveys (Dighem, magnetic and IP), across the A12 Prospect display similar styles of signature to those recorded across the adjacent Jugan Deposit. However, the presence of silica alteration at the surface of A12 is not recorded across the surface of the Jugan Deposit. Either the A12 structural block has been uplifted, or alternatively, it has been exposed to more pervasive silicification because extensive drilling results show that such silica alteration is only evident in the Jugan Deposit at depths greater than 150 m subsurface. Both explanations raise the possibility that the host
Besra's upcoming drilling program will include drill testing strike extensions of the Jugan mineralisation into the A12 Prospect precinct.
