"A12" Target a Potential Significant Jugan Deposit Extension
- The Jugan Deposit contains 960 koz @ 1.56 g/t Au (JORC 2012), within the wider Bau Gold Project which hosts a total gold Resource of 73.6 Mt @ 1.43 g/t for 3.3Moz1.
- A significant new gold anomaly, 'A12', has been identified along strike and circa 1km from the large Jugan Deposit.
- A12 exhibits similar geophysical and geochemical signatures to the Jugan Deposit only significantly larger in scale and possibly more prospective.
- Unlike the Jugan Deposit, the surface outcrops of A12 exhibit extensive silica alteration, suggesting A12 host rocks have been more susceptible to space forming brittle fracture and consequently potential for enhanced mineral endowment.
- The A12 Prospect is planned to be drilled in the upcoming drilling programs, with rigs mobilising shortly.
- Besra will commence its drilling program at the Bau Gold Field within two weeks, and this will include investigating strike extensions of the Jugan mineralisation within the A12 Prospect precinct.
Perth, October 26, 2021 - Besra Gold Inc. (ASX: BEZ) ("Besra" or the "Company") announces the identification of a significant new gold anomaly in close proximity to the Jugan Deposit. The Jugan Deposit contains 960 koz @ 1.56 g/t Au (JORC 2012), within the wider Bau Gold Project which hosts a total gold resource of 73.6 Mt @ 1.43 g/t for 3.3Moz.
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 (Figure 1). 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 (Figures 2 & 3).
Figure 1 - A12 lies approximately 1 km from Jugan along a WSW trending localised mineralised corridor defined by the Jugan - Sirenggok deposits.

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 Pedawan Shale host rocks more susceptible to brittle fracture with potential for greater mineralisation endowment.
- 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 Pedawan Shale lithologies at A12 were more susceptible to brittle deformation following silica alteration with the consequential potential for the endowment of higher mineralisation grades occurring closer to the surface.
Besra's upcoming drilling program will include drill testing strike extensions of the Jugan mineralisation into the A12 Prospect precinct.
