Our exploration investment TechGen Metals (ASX: TG1) just put out an exploration update across its two WA copper, gold, silver and antimony prospects:

Blue Devil (Copper-gold-silver) - Here TG1 has 2 targets from an EM survey and plans to drill as soon as this quarter. Next is awaiting the final report of the heritage survey which once approved will allow drilling to commence.
Mount Bogolla (Copper-gold-antimony) - here TG1 has 2 targets, and plans to drill following the pending heritage survey, so could be this year. Next up is the results of the IP survey completed recently which could add more drill targets to the southwest.

The two big drill programs we are looking out for are:

Blue Devil (WA Copper-gold-silver)

At Blue Devil (our favourite target), TG1 has kicked off an IP geophysical survey.

Here TG1 already has 2 targets and is looking to drill this project at some point between Q4 2025 and Q2 2026.

The IP geophysics underway will give us a better idea of where TG1 should put its first round of drillholes.

Prior, TG1 has completed a heritage clearance survey at the project and is waiting on the final report before moving forward to signing heritage agreements.

The heritage agreements are a precursor for TG1 being able to get on the ground here.

Here are the targets where TG1 has rock chips (grading up to 50.5% copper and 18g/t gold) lining up with big EM targets:

Mt Boggola (Copper-gold-antimony)

At Mt Boggola, TG1 has completed the stage 2 IP survey (green lines, prior survey in purple).

TG1 Wants to drill this project this quarter.

Here TG1 has previously identified two copper-gold drill targets (MB1 and MB2):

The IP survey recently completed are to the south west of the MB1 and MB2 targets, including covering a high chargeability zone.

These will be looking to see if there are additional targets close to a previous chargeability highs AND where previous Newcrest holes ended in sulphide mineralisation.

TG1 also confirmed in today’s announcement that heritage surveys for Mount Boggola have been rescheduled by a few weeks and now expected to begin the 21st of October.

Previously, Mount Boggola was drilled in 2022 by TG1 and $21BN Newcrest back in the 1990’s.

Since then TG1 ran some new 3D modelling of the IP targets here and it turns out, all of that old drilling missed the big chargeability anomalies by “matter of ten to twenty metres”.

For anyone new to exploration IP targets are generated when a company measures chargeability under the surface (basically checking to see if the rocks underground are conductive).

Higher chargeability is usually a good signal for somewhere to drill to find copper mineralisation.
