TechGen continues aggressive gold and copper exploration programs

For newly-listed gold and copper explorer TechGen (ASX: TG1), the last few months have been busy.

For newly-listed gold and copper explorer TechGen (ASX: TG1), the last few months have been busy.

Exploration works completed since listing include:

Blue Rock Valley Project, Ashburton Basin

  • Airborne EM survey commenced on the 7th April and was completed on the 9th April.
  • A total of 928 line km was flown.
  • The survey identified 2 conductors on E08/3030.


El Donna Project, Yilgarn Craton

  • RC drilling at the El Donna Project commenced on the 30th March and was completed in early April.
  • 11 holes for 1,346 metres were drilled.
  • Four metre composite samples (373 samples) were submitted to ALS Laboratories for gold assay.
  • Assay results were received in May. Best results included 8m @ 1.3g/t Au from 56m (hole ELRC003) and 8m @ 1g/t Au from 84m (hole ELRC004).


Ida Valley Project, Yilgarn Craton

  • RC drilling at the Ida Valley Project commenced on the 30th April and was completed in early May.
  • 11 holes for 990 metres were drilled.
  • Four metre composite samples (281 samples) were submitted to ALS Laboratories for gold assay.
  • Assay results awaited.

In April, TechGen’s maiden drill program at its El Donna project uncovered exceptionally high-grade gold samples (250g/t gold) at the Star Prospect site, in the Ashburton Basin in Western Australia (WA). The company also completed a heliborne versatile time-domain electromagnetic (VTEM) survey at its Blue Rock Valley gold Project in April, also in the Ashburton Basin, which revealed three strong conductors in the bedrock.

TechGen is now continuing its aggressive exploration across Western Australia’s Goldfields and Ashburton regions and has since launched a series of new exploration programs across its highly prospective projects.

Mt Boggola

TechGen this week commenced a VTEM-Max Survey at the Mt Boggola Project in the Ashburton Basin of WA, to identify possible copper sulphide mineralisation at depth across the entire project area. 

The survey consists of approximately 320 line kilometres of surveying with nominal 200m spacing between flight lines.

Historic work at the Mt Boggola project has identified areas of high-grade copper, silver and gold within a number of outcropping gossans.

Recent analysis of a rock sample which assayed 48.7% copper and 119g/t silver, has indicated the presence of copper sulphides, in addition to copper oxide minerals. 

This survey is anticipated to be completed this week.

Station Creek

TechGen also recently completed a heliborne VTEM-Max survey over Station Creek, a highly prospective copper project in the Ashburton basin, to explore for sulphide mineralisation at depth.

Key features within Station Creek are major fault structures, magnetic anomalies and high-grade copper rock chips up to 54.7% purity; this highly prospective site has been underexplored with modern technology. 

The VTEM survey included around 300 line kilometres of surveying with nominal 200-metre spacing between flight lines. The survey covered the entire project area.

Previous exploration has indicated the presence of copper sulphide and copper arsenate minerals at surface from a species identification process, XRD analayis.3 

With the survey completed, TechGen is now awaiting final detailed and modeling results.

Ida Valley

The company’s Ida Valley Gold project is now undergoing an additional and extensive gold geochemistry sampling program within a new mineralised greenstone belt, yet to be named by the Company. The geochemistry program has commenced prior to the release of assays from the recently completed RC drilling campaign that consisted of 11 holes for 920m. The RC program was based on a highly encouraging 2020 geochemistry sampling that identified a peak sample of 884ppb of gold and 6.6g/t gold in a rock chip. The style of geology and sulphides within the logged RC drilling lead the company to commence the current geochemistry program earlier than previously planned. 

The project, in the Yilgarn Craton of WA, has up to 30 kilometres of prospective strike extent. It consists of three Exploration Licences covering a combined area of 199 square kilometres.  

Peak results from the project to date are 884 ppb gold in soils and 6.6 g/t silver in rock chips.6

Assay results from the reverse circulation drilling in May are pending.
