Drilling Continues to Define Larger Scale to Burns Au Cu System

Lefroy Exploration Limited (ASX: LEX) (“Lefroy” or “the Company”) is pleased to provide a progress report for the two-hole diamond drill program underway at the Burns Au-Cu intrusion-related mineral system. Burns is within the Company’s wholly owned Eastern Lefroy Gold Project, located 70km southeast of Kalgoorlie. The first hole, LEFD006, has been completed to a downhole depth of 1245.8m, with the second hole, LEFD007a, located 240m to the south now underway.


  • The EIS co-funded diamond drill hole, LEFD006, has been completed to a downhole depth of 1245.8m. This is the deepest hole completed at Burns to date.
  • LEFD006 intersected a suite of diorite-porphyry units over a broad 195m downhole interval, from 710m to 905m. These units are broadly grouped as the Central Porphyry, and has established that the vertical continuity of the intrusive system previously found by shallower drilling extends to 1000m from surface and that it remains open for further extension along strike and at depth
  • In addition, the hole has established four key geological domains, including the Central Porphyry suite, which when combined define a 600m width to the intrusive system and provide further evidence that Burns is a large-scale mineral system.
  • Each of the four geological domains has a different alteration and mineralisation assemblage, which evidences that Burns is a multi-stage mineral and porphyry system.
  • Core samples from LEFD006 have been submitted in batches to the laboratory, with first results expected in September
  • The second diamond drill hole, LEFD007a, is at 231m downhole, with a planned 500m hole depth. LEFD007a is 240m south of LEFD006 and has intersected multiple intervals containing native copper within the altered Western Basalt (see below).
Lefroy Exploration Managing Director Wade Johnson said “This is an exciting phase of drilling at Burns where we are now demonstrating the larger scale of the alteration zonation and the extent of the multiphase porphyry intrusions, which extend to at least 1000m below surface. There is a large body of altered rock outboard of the Central Porphyry, with a width of at least 600m, which now extends at least 240m to the south of LEFD006, as observed in LEFD007a. We continue to believe it is indicative of a mineralised, hydrothermal, Archean- age porphyry system, with an alteration footprint that is broader than we have anticipated.”

Burns is a new and unique style of an intrusion-related, gold (Au)-copper (Cu)-molybdenum (Mo)-silver (Ag) mineral system, hosted by Archean age rocks in the Eastern Goldfields Province (EGP) of Western Australia. LEX is aiming to advance the understanding of the scale and genesis of the system through this deep drilling program.

The gold, copper, silver (and lesser molybdenum) mineralisation, hosted by multiple, diorite-porphyry intrusives and high-magnesium basalt, are considered by the Company to be a new and unique style of gold-copper mineralisation near Kalgoorlie, located within a land holding dominated by LEX.

Editor's Picks: Gold Price Breaks US$3,400, Silver Added to Draft US Critical Minerals List

The gold price was on the rise this week, breaking through US$3,400 per ounce once again.

It's been pushed higher by US dollar weakness, as well as Federal Reserve turmoil.

President Donald Trump has been pressuring Fed Chair Jerome Powell to cut interest rates for months, and on Monday (August 25) the situation developed further when Trump posted a letter on his social media platform Truth Social. In it, he said he was removing Lisa Cook from her position on the central bank's board of governors due to allegations of mortgage fraud.

Top 5 Canadian Mining Stocks This Week: Trifecta Shines with 117 Percent Gain

Welcome to the Investing News Network's weekly look at the best-performing Canadian mining stocks on the TSX, TSXV and CSE, starting with a round-up of Canadian and US news impacting the resource sector.

Statistics Canada released its second-quarter gross domestic product (GDP) figures on Friday (August 29). The data showed that the Canadian economy shrank 0.4 percent in the second quarter and declined 1.6 percent on an annualized basis. The decrease comes following first-quarter gains of 0.5 percent and a 2 percent annualized increase.

Much of the decrease was attributed to a 7.5 percent drop in exports compared to Q1. Canadian exports had risen 1.4 percent in the first three months of the year as US companies increased imports to get ahead of incoming tariffs.Excluding the lower costs at the pumps, CPI remained steady at 2.5 percent, the same increase as May and June.

Navigating Uncertainty: How Trump's Tariffs Are Affecting the Gold Market

The gold price has been on the rise in 2025 as a slew of factors work in its favor.

Central bank buying has long been a key point of support, as has escalating conflict in the Middle East and elsewhere. A newer addition is tariff tensions as the Trump administration fleshes out trade policies.

The gold price has benefited from safe-haven demand amid the turmoil, but concerns that the yellow metal itself might face tariffs have also impacted the sector as industry insiders react to uncertainty.
