Brightstar hits high-grade gold in final assays | Australian Markets

Brightstar Assets has recorded a best hit of 20.39m at 3.03g/t gold in ultimate assays from final 12 months’s diamond drilling marketing campaign at its Jasper Hills gold project in WA’s Japanese Goldfields.

The complete gap tells a more fascinating story with a 6.42m intercept at 2.7g/t from 184.88m previous the headline hit. The larger intercept consists of 1.36m at 9.23g/t gold from 198.21m and a pair of.34m at 7.72g/t gold from 205.53m.

The 13-hole mixed reverse circulation (RC) and diamond coring program was designed to guage areas across the $3000 optimised pit shell at Brightstar’s Lord Byron deposit, within its Laverton hub. This system included infill drilling in deeper components. It aimed to increase the company’s confidence in its geological interpretation earlier than an imminent replace to its mineral useful resource estimate.

The diamond drilling program totalled 13 drill holes, together with seven diamond tails to increase earlier 2024 RC drill holes for a whole of about 1700m of coring. Brightstar now has all of the ensuing assays at hand.

The extra benefit of the deep diamond coring implies that sound rock materials was dropped at floor to offer the best potential metallurgical and geotechnical media for mine and course of planning.

The headline 20.39m hit intercepts the principle Lord Byron mineralised physique much less than 20m under the $2500 optimised pit flooring and is the best intercept inside the $3000-shell.

It provides additional help to the continuity of mineralisation within the physique over about 40m down-dip to the present deepest three intercepts in one other gap additional down-dip.

The outlet with the deeper intercepts was collared off part however at depth it intercepts the identical part because the headline hit.

The three deep gold intercepts gave up 7.8m grading 4.07g/t, together with 1m at 10g/t gold from 238.5m, 3.6m assaying 1.21g/t and 4.4m going 2.28g/t from 264m gold on the backside of the shell. Present interpretations point out the physique would possibly bifurcate close to the design pit flooring.

A new gap across the center of that 40m no-man’s-land between intercepts and a second one about 40m under the pit flooring will decide if the obvious bifurcation is actual.

4 different diamond holes additionally present encouraging outcomes with main intercepts within the vary of 13m to virtually 23m with average grades between 1.56g/t and a pair of.53g/t gold. Three intercepts are spiced up with 0.3m, 0.6m and a pair of.7m intercepts assaying 17.3g/t, 10.3g/t and 5.83g/t gold respectively.

The company says the outcomes outline constant high-grade, south-plunging shoots offering wonderful targets for the potential enlargement of the pit shells and underground mining concerns.

These extremely encouraging outcomes reinforce Lord Byron’s place as a vital gold useful resource within the company’s portfolio. The elevated geological understanding and extra metallurgical and geotechnical knowledge will contribute to up to date development research at our Laverton hub. The outcomes spotlight vast intervals of open-pit mineable gold grades, together with discrete zones of high-grade mineralisation recognized close to the bottom of and under a $3,000/ounce optimised pit shell generated during a 2024 scoping examine.

The Lord Byron mineralisation is hosted by a package deal of amphibolite and banded iron items, that are cross-cut by the northwest-trending Bicentennial shear zone, a 100m-wide zone of shearing which hosts the deposit’s major zone.

Further mineralisation may also be recognized in supergene lodes and as main gold within the banded iron items which were deflected and truncated by the Bicentennial shear construction.

Assay outcomes have additional outlined a number of south-plunging, high-grade shoots in the principle zone of mineralisation on the deposit within the Bicentennial shear.

Inside the deposit’s 800m strike, the longitudinal part reveals that the principle zone extends for more than 200m alongside strike, and plunges at about 45 levels. It orientation is mirrored by two different shorter mineralised zones to its southeast, with one extending about 100m and the about 30m alongside strike respectively.

All three zones are open at depths under about 220m under floor. Different current drilling outcomes level to their doubtless sturdy potential for depth continuity under the present pit shells.

These observations augur effectively for future potential pit deepening and cutbacks, together with consideration of potential underground mining.

As all the time, such projections to depth are tough when the ultimate arbiter is the gold price. Whereas the yellow steel’s meteoric efficiency reveals no signal of abating, it doesn’t harm to carry future useful resource alternatives to thoughts, particularly with greater grades exhibiting up at depth.

Brightstar is now planning extra drilling at Lord Byron later this quarter to focus on the principle shoots at depth upfront of assessing its potential for future open pit cutbacks or underground mining under the deliberate open pit.
