Significant Intercept of 31 m at 6.1 g/t Au at Sorowar – Pigiput Trend
Highlights
Assay results have been received for the first 13 resource definition, exploration and sterilisation drill
holes (SDH570 to SDH582) from the FY25 Simberi drill program, significant intercepts from the
Sorowar – Pigiput Trend include:
o SDH576: 31 m @ 6.1 g/t Au from 35 m, including 8 m @ 20.1 g/t Au from 53 m, including
4 m @ 37.8 g/t Au from 54 m,
o SDH578: 45 m @ 1.5 g/t Au from 5 m,
o SDH580: 25 m @ 1.9 g/t Au from 17 m, including 3 m @ 8.2 g/t Au from 35 m,
o SDH581: 31 m @ 1.7 g/t Au from 96 m, including 8 m @ 3.9 g/t Au from 111 m,
o SDH582: 20 m @ 2.3 g/t Au from 21 m, including 8 m @ 4.2 g/t Au from 25 m and 19 m @
2.8 g/t Au from 50 m, including 14 m @ 3.5 g/t Au from 52 m.
• Resource definition holes SDH576 and SDH582 both intersected significant near-surface higher-
grade mineralisation, extending vertically between 15 m and 40 m below the sulphide Ore Reserve
pit design.
• Mineralisation intersected in both SDH576 and SDH582 remains open along strike to the southeast
and down dip.
St Barbara Limited (“St Barbara” or the “Company”) (ASX: SBM) is pleased to announce the completion of
24 diamond drill holes from the proposed 62 hole FY25 sulphide drilling program, with assay results returned for the first 13 holes (including sterilisation drill holes SDH572, SDH577 and SDH579)
These include the first new results reported from the Sorowar – Pigiput Trend since June 2024 (refer to the ASX release on 17 June 2024 titled “More Encouraging Assay Results from Sorowar – Pigiput Mineralised Zone”). This series of results forms part of the FY25 resource definition, exploration and sterilisation drill program comprising 62 holes for 9,000 m that commenced on 1 July 2024 at the Simberi Operations in Papua New Guinea (PNG). The program includes approximately 4,750 m of resource definition drilling at both the Sorowar-Pigiput Trend and the Samat deposit; and approximately 4,250 m of exploration and sterilisation drilling testing in six further areas. Drilling is progressing ahead of schedule with approximately 40% of the overall program completed.
St Barbara Managing Director and CEO Andrew Strelein said:
“The decision to move quickly to follow up on the FY24 discovery of the new Sorowar – Pigiput mineralised zone has been rewarded with hole SDH576 returning 31 metres at 6.1 g/t Au from just 35 metres, including 8 metres at 20.1 g/t Au.”
“This assay result is another very encouraging broad intercept at shallow depth in this new mineralisation
zone between Sorowar and Pigiput pits, located immediately below the sulphide Ore Reserve pit design.
Hole SDH533, drilled as part of our FY24 program, is located 27 m immediately up-dip and forms part of the same trend, and returned 45 metres at 2.2 g/t Au from 0 metres including 10 metres at 5.1 g/t Au from 26 metres. An additional hole is planned to test the mineralisation 40 metres down dip from hole SDH576, some 50 metres below the sulphide Ore Reserve pit design.”
“Hole SDH582 included 20 metres at 2.3 g/t Au from 21 metres and 19 metres at 2.8 g/t Au from 50 metres
and is another very encouraging intercept at shallow depth in between Sorowar and Pigiput pits, located
between 15 and 40 metres vertically below the sulphide Ore Reserve pit design.”
“The shallow high-grade mineralisation intersected in both SDH576 and SDH582 remains open along strike to the southeast and down dip to the southwest.”
“During the December quarter we anticipate the return of assay results for the remainder of the 24 resource definition, exploration and sterilisation holes drilled to date at Sorowar – Pigiput trend and Pigibo North. The sterilisation and exploration holes have been proposed to close out the mineralisation boundaries and are important for the finalisation of pit designs and waste deposition plans.”
