The Mulline Trend is located 10 kilometres southeast of Riverina and has historically produced more than 250 koz of Au predominantly from the Lady Gladys and Giles open pit mines, but also numerous shafts and early prospector mines.

In 2025 a focused mapping project commenced at Mulline to develop a new geological and mineralisation model to provide new high quality exploration targets.

A focused exploration drill program is underway to test this newly developed exploration model and high quality gold targets.
