HAR starts drilling US gold project in California

Our gold Investment Haranga Resources (ASX: HAR) just started drilling on its US gold project in California.

HAR’s project sits in the Motherlode region in California - the epicentre of the original Californian gold rush.

The project has ~US$90M of infrastructure, including a processing plant and an underground decline (which is where HAR is now drilling from).

The project has a 286,000 oz foreign resource (source) and data from a 2008 report shows it could actually host up to ~682,000 ounces. (source)

With this round of drilling, HAR will be looking to convert those into JORC compliant resource estimates.

HAR is now the first company to drill this project in over 12 years which is pretty surprising considering gold has gone on 2-3 runs over that period.

Here is an image of the drill rig in action:

HAR has 25 holes planned for ~2,600M of drilling across 6 different zones:

HAR has also left room to add additional drilling holes depending on early results.

Drilling is expected to operate 24/7, with only a possible short break during the Christmas period depending on dewatering progress.

(so we could get some newsflow between now and early January (if the drilling hits anything interesting)

Here is a cross section which helps visualise the drilling a lot better too - basically, we want to see gold in those yellow lines, the closer they are to the grey decline (and higher grade) the better:

With this first round of drilling HAR will be looking to:

1. Announce a maiden JORC resource - by converting the existing 286k ounce historical resource into a JORC-compliant mineral resource, targeted for late January 2026.
2. Test for extensions and repetitions (new discoveries) of the mineralisation at depth.

Update on Dewatering and Infrastructure

Looking at that drill plan from earlier we can see HAR plans to step down deeper into the underground decline to run the next batch of holes.

So we are also watching to see any updated on dewatering which will ultimately determine access to those deeper levels:

Not long to go now before the full decline is dewatered…

Maybe next time we are on site, we will get to go down into the decline. The last time we were there we could only look down into the decline from the front gate.

Here is a picture from our site visit earlier in the year at the entrance to that decline:

We are also looking to see what happens at HAR’s Senegal gold project

Earlier this week, HAR completed the second phase of aircore drilling on the project completing 65 holes - looking to extend the area HAR’s project covers:

Assays from the second phase of drilling are expected next month.

The whole purpose of the second phase of drilling is to setup drill targets that HAR can come back and drill with deeper RC/Diamond drillholes.

HAR expects that deeper drill program to start in early 2026.

The phase 2 drill program started only 8 weeks after the initial results from that first round of drilling.

The initial results included a headline worthy result of 20m @ 6.54g/t gold from just 12m depth which we initially covered here.
