Multiple High-Grade Hits with Visible Gold Intercepted at Cork Tree Well

Brightstar Resources Limited (Brightstar or the Company) (ASX: BTR) is pleased to announce the initial assay results from the first two diamond drillholes at Cork Tree Well (CTW) within the Laverton Gold Project (LGP). These two holes, as part of a broader 20 hole program1, were completed in January 2024 with satisfying progress being made by Brightstar’s diamond drilling contractor and geology team.


HIGHLIGHTS

  • Assays received from first two diamond holes completed at Cork Tree Well with numerous high grade gold assays up to 172.41g/t Au returned
  • Multiple instances of visible gold observed in cut core supports high grade results
  • Intercepts returned include 34.4m at 7.94g/t Au from 43.5m (CTWMET004), including
    • 8.4m at 13.47g/t Au from 43.5m, and
    • 3m at 7.05g/t Au from 54m, and
    • 15.6m at 8.23g/t Au from 58m
  • CTWMET004 was drilled in the virgin Delta deposit at Cork Tree Well North, with the gold mineralisation entirely contained with a mafic metadolerite and quartz breccia unit
  • The Delta deposit remains completely open at depth, with the deepest hole previously drilled intercepting 31m @ 2.12g/t Au from 172m beneath the current open pit shell
  • Assays received from CTWMET002 below the historical open pit at Cork Tree Well include:
    • 6.5m at 1.42g/t Au (from 104m)
    • 1.65m at 1.82g/t Au (from 112m)
  • Two remaining holes (CTWMET003 and CTWMET001) prioritised for expedited turn- around, with another 16 holes pending drill completion & processing for PFS workstreams

Brightstar’s Managing Director, Alex Rovira, commented“These holes were the first diamond holes drilled at Cork Tree Well by Brightstar, with our understanding of the geological model and mineralisation styles defined by over 28km of previous Brightstar RC drilling being enhanced by the knowledge being gained from this +2,000m diamond core program currently in progress.

We have reinforced our view that the gold mineralisation at Cork Tree Well is structurally hosted, with a mafic metadolerite host rock observed in CTWMET004 at Delta, whilst gold mineralisation returned in CTWMET002 is positioned within a chert-breccia horizon in the sedimentary package underneath the shallow historically mined open pit.

Due to the high grades returned, several re-assays were completed to cross-check the veracity of the initial result in certain cases, with multiple high-grade re-assays and visible gold supporting a coarse-grained nuggety gold mineralisation model at Delta.

In order to provide sufficient rock mass for the metallurgical test work purposes across all oxidation states at the Delta (oxide, transitional and fresh), CTWMET004 was drilled sub-parallel to the ore body at Delta. Importantly, Delta is still open at depth with the deepest hole in the vicinity, SDR126001, returning 31m at 2.12g/t Au2 highlighting the immense potential for high grade depth extensions.

Given the inaugural diamond drilling results thus far, we remain of the view that we’ve barely scratched the surface at Cork Tree Well, with strong potential to build on the existing 303koz @ 1.4g/t Au Mineral Resource3 both at depth with high-grade plunging shoots and strike extensions targeting the structurally-controlled mineralised trends across geological units.

We look forward to updating our stakeholders with more information on our diamond program, including the expedited assays for CTWMET001 and CTWMET003. These four diamond holes will form the basis for metallurgical testwork within our Pre-Feasibility Study4 which envisages the broader Cork Tree Well project to form the baseload ore feed to our wholly owned processing plant and associated infrastructure located ~30km south of Laverton”.

Due to the nuggety and high-grade nature of the gold mineralisation observed in CTWMET004, multiple samples had repeat assays completed following from best QA/QC laboratory practice. The repeat fire-assays provided additional analytical insight into the nuggety nature of mineralisation in addition to the visible gold observed. Where multiple repeat assay runs occurred, an average of the results has been used in the reporting in Table 1 above and within this announcement. The full break-down of the re-assayed samples are outlined below in Table 2. Repeat assays were not conducted on all fire-assay samples and significant intercepts reported in this announcement will be re-evaluated following from planned additional analyses using a larger sample mass, towards a better representation of the mineralisation at Cork Tree Well and within the ‘Delta’ deposit.

Brightstar will be conducting continued analysis into the effects of the nuggety gold at Cork Tree Well, and specifically within the ‘Delta’ deposit, in future drilling programs. Metallurgical analyses in addition to re- assaying more samples using additional analytical methods (incorporating a greater sample mass) will assist with continued understanding of the nature of mineralisation. Additional analytical methods will commence with screen fire assaying to identify and better quantify the presence of coarse gold with photon analyses considered in conjunction with screen fire assaying processes.

Top 10 Gold Reserves by Country

Gold is one of the most important metals on the planet. For millennia it has been used in jewelry, art and currency, capturing the collective imagination as a thing of wonder. Gold's association with royalty and wealth has inspired explorers and treasure hunters alike, who put themselves at risk for a chance to strike it rich.

Today, gold's hold on us as a precious metal is no less powerful. Still used for jewelry and as a store of wealth, the metal also has a variety of modern industrial and electronic applications.

Even though gold seems to be everywhere, in reality it's a finite resource. Only 244,000 metric tons of gold have ever been mined, and two-thirds of that has been extracted since 1950. Comparing that amount to the more than 700 million metric tons of copper that have been pulled from the ground provides an idea of how precious a resource gold truly is.

A Guide to Investing in Physical Gold (Updated 2024)

Gold is known as an attractive safe-haven investment and has been used to store wealth during volatile times through history.

It has interesting currency-like tendencies, and retains its purchasing power better than paper currencies.

For that reason, gold market analysts typically recommend that investors build a diversified portfolio with a portion of their wealth in gold bullion. Here the Investing News Network explains what's involved in building and managing a physical gold portfolio.
