    Lefroy Exploration launches 15,000m RC drilling at Burns gold copper prospect, Western Australia

    Lefroy Exploration (ASX:LEX) reports that it has started a major reverse circulation (RC) drilling operation at the Burns gold copper prospect, as part of its 100% owned Eastern Gold Project in Western Australia.  

    The RC drilling operation has commenced with a goal of testing the new and unique Burns gold (Au)-copper (Cu)-molybdenum (Mo)-silver (Ag) mineral system in WA’s Eastern Goldfields Province. 

    Drilling is expected to test to a depth of about 200m from surface and will cover a 700m by 500m mineralised footprint that will extend north and east into Lake Randall.   

    The major campaign will consist of 15,000m of drilling and is expected to be completed in January 2023, with generated results and data to be used to deliver a maiden shallow gold-copper Mineral Resource Estimate (MRE) for the Burns prospect, which is scheduled for the March quarter in 2023.  

    Drilling will be both land-based (onshore) and on Lake Randall (offshore).  

    Commenting on the RC drilling operation, Lefroy Exploration Managing Director, Wade Johnson, stated: “This is another exciting period of exploration at Burns and immediately following in from the completion of the four diamond drill holes both at Burns and Lovejoy.

    “The rc drilling is focused on the shallow portion of the larger burns system and deisgned to deliver a maiden gold copper resource”

    The RC drilling is focused on the shallow portion of the larger Burns system and designed to deliver a maiden gold copper resource. This close spaced drill data will also provide detailed geological information to guide further deeper exploration at Burns and also at multiple targets along the Burns corridor.”

    The company also notes that targeted aircore (AC), RC and diamond drilling (DD) at Burns since January 2021 has defined the broad footprint of the mineralised system, however the limit of mineralisation is yet to be defined. 

    In addition, the integration of 3D metal models including Au, Cu and Mo sourced from the extensive multi-element drill database has also provided an enhanced interpretation of the geometry of the Burns mineral system.

    Drilling has also highlighted a large, northwest trending, southerly plunging mineralised shell, which is host to a ‘higher grade’ northerly trending Au-Cu component that was recently tested by diamond drillholes. 

    This northerly trending, ‘high-grade’ zone is further supported by recent AC gold intersections at Lake Randall, which returned intercepts of 24m at 2.86g/t Au from 16m, about 240m north of discovery drillhole LEFR260. 

    Lefroy Exploration is an ASX-listed, Western Australian based exploration company taking a methodical, disciplined and conceptual approach in the search for high value gold deposits in the Yilgarn Block of WA. The company’s two key projects within the region include its same-named gold project near the township of Kalgoorlie and the Lake Johnston Project located about 120km to the west of the township of Norseman. 

    Lefroy’s same-named flagship gold project is located southeast of the township of Kalgoorlie and is split into Eastern and Western Lefroy, covering a total land holding of 534km-square within the heart of the world class gold production area between Kalgoorlie and Norseman. Lefroy currently holds 100% ownership of all associated tenements, however major gold producer, Gold Fields, is currently working towards farming into and managing exploration at the Western part of the project.         

    With the land based (onshore) component now underway, Lefroy Exploration announces that it has secured a specialised lake RC drill rig and expects drilling at Lake Randall to commence in late October.  

    Samples taken from the RC program will be prioritised for gold analysis ahead of copper, silver and cobalt, with first assays expected in November.
