SnapshotMeekatharra Gold Operations (MGO) includes the historic gold mining centres of Meekatharra North, Paddy’s Flat, Yaloginda, Nannine and Reedy’s.

The MGO processing hub incorporates the 1.6-1.8 Mtpa Bluebird processing plant, which treats ore from the Meekatharra Gold Operations’s mines, surplus ore from Big Bell mine (Cue Gold Operations) and various surface stockpiles in the region.

The Bluebird underground mine has been expanding rapidly since recommencement of mining in mid FY22. With the expansion of Bluebird underground, at the end of FY22, mining operations at South Emu - Triton in the Reedy’s area was paused to reassess its economics.

At the end of Q3 FY24, mining operations at the Paddy’s Flat was paused, to allow the mine to transition to an exploration phase, targeting a restart of the mine once a 3-4 year mine plan is defined.

Sub-level open stoping commenced in August 2024 on the South Junction Lode, within the Bluebird-South Junction mining complex.

Summary:

The Meekatharra Gold Operations (MGO) is located in the Achaean Murchison Province, a granite-greenstone terrane in the northwest of the Yilgarn Craton. Greenstone belts trending north-northeast are separated by granite-gneiss domes, with smaller granite plutons also present within or on the margins of the belts.

The Paddy’s Flat area is located on the western limb of a regional fold, the Polelle Syncline, within a sequence of mafic to ultramafic volcanics with minor interflow sediments and banded iron-formation. The sequence has also been intruded by felsic porphyry dykes prior to mineralisation. Mineralisation is located along four sub-parallel trends at Paddy’s Flat which can be summarized as containing three dominant mineralisation styles:
• Sulphide replacement BIF hosted gold. Quartz vein hosted shear-related gold.
• Quartz-carbonate-sulphide stockwork vein and alteration related gold.

The Yaloginda area is a gold-bearing Archaean greenstone belt situated ~15km south of Meekatharra. The deposits in the area are hosted in a strained and metamorphosed volcanic sequence that consists primarily of ultramafic and high-magnesium basalt with minor komatiite, peridotite, gabbro, tholeiitic basalt and interflow sediments. The sequence was intruded by a variety of felsic porphyry and intermediate sills and dykes.

The Reedy’s mining district is located approximately 15 km to the south-east to Meekatharra and to the south of Lake Annean. The Reedy gold deposits occur with- in a north-south trending greenstone belt, two to five kilometres wide, composed of volcano-sedimentary sequences and separated multiphase syn- and post-tectonic granitoid complexes.

The Paddy’s Flat Trend is mineralised a strike length of >3,900m, a lateral extent of up +230m and a depth of over 500m.

Bluebird is mineralised a strike length of >1,800m, a lateral extent of up +50m and a depth of over 500m.

Triton – South Emu is mineralised a strike length of >1,100m, a lateral extent of several meters and a depth of over 500m.
