Rebranded Pilbara Gold (ASX: PGL) is ramping up drilling at its 2.1 million ounce Mt York Gold project in Western Australia, where a 50,000-metre drilling program is well underway to test the extensions of the deposit.

Previously known as Kairos Minerals, shareholders voted to change the company’s name to Pilbara Gold in late April. Three diamond rigs are currently drilling double shifts at the project, with two additional RC rigs expected in June.
“We are very excited to be drilling the Mt York Gold Project again, with the aim of increasing and upgrading resources at this quality asset. The technical team has already started to see interesting core, and we anticipate to have initial results flowing in a matter of weeks,” managing director Dr Peter Turner said.
“We are busy planning an airborne electromagnetic (AEM) survey at Mt York. The foundation dataset that this cost-effective survey generates will be used to directly target buried gold deposits over a large portion of our prospective land package surrounding Mt York.”
The three diamond drill rigs were deployed to Mt York from early April to commence the largest drilling program over the asset in the company’s history.
To date, 5,680 metres of drilling in 19 holes have been completed at Gossan Hill, Breccia Hill, Main Hill Extension and Gilt Dragon.
Mt York currently hosts 2.1Moz of gold in a continuous, 4.2km-long banded iron formation (BIF), and the 50,000m drill program in CY26 is targeting a significant increase in gold resources at depth along the entire 4,200m BIF host rock.
The drilling began on the extension of the deposit, where CY25 drilling only tested the top 100m. PGL’s drilling in 2026 is following up on results of 9m at 3.92 grams per tonne from 97m and 16m at 2.6 g/t from 143m.
The drilling has successfully hit several BIF units, which to date have been the host for gold mineralisation. Strongly altered BIF was intercepted across multiple drill holes at the Main Hill Extension prospect. Notably, visual logging identified moderate-to-strong arsenopyrite development, which typically serves as the primary indicator mineral for high-grade gold mineralisation within the project area.
Structural logging of the drilling data at Main Hill Extension successfully defined the first of several interpreted north-south trending cross faults, which offset the targeted mineralised BIF by 30-50 metres at both Main Hill and Main Hill Extension. Resolving this structural offset provides immediate benefit for predicting the expected positions of mineralised BIF for planning subsequent drillholes.
First results are expected to start flowing from late July. The drill program will ramp up over the course of the next month, with two RC drill rigs joining the three diamond drilling rigs already on site.
The RC rigs will be deployed mostly to drill pre-collars to the deeper diamond holes under Main Hill, Main Hill Extension, Breccia Hill and to a lesser extent, Gossan Hill.
PGL is up +3.18% to 56.8¢.
