Recent field observations and 2025 surface assay results have delineated a gold-copper anomaly at West Wing measuring approximately 1,500m by 800m.
The recent field work highlighted seven rock samples grading approximately 3.0 grams per tonne (g/t) gold including a high of 15.5 g/t and 16 soil samples grading around 1.0 g/t gold with a peak of 3.8 g/t.
The sampling also returned three rocks grading approximately 1.0% copper with a high of 6.9% and 16 soil samples grading around 0.2% copper with a high of 0.55%.
GM and geologist, Hans Hoffman, said the results build on earlier surface reconnaissance at West Wing which returned rock samples of up to 25.8 g/t gold.
“Field crews covered a lot of ground at Estelle in 2025 focusing on the less developed prospects and exploring for new ones,” Mr Hoffman said.
“The most outstanding results came from West Wing where geologists were following up on two soil samples round 1.0 g/t gold from 2024. Multi-gram gold and multi-percent copper rock samples were also reported.
“While a majority of the samples were collected in hornfels adjacent to the Estelle pluton, a few soil samples were collected atop a quartz feldspar porphyry, suggesting West Wing could be a different deposit style than is typical for Estelle.”
Nova will prioritise detailed mapping and drill targeting at West Wing in 2026.
Mr Hoffman said unlike a majority of the prospects at Estelle, the West Wing anomaly is primarily hosted in hornfels sedimentary rock, although it is adjacent to the Estelle pluton.
“Out of all the soil anomalies identified at Estelle, West Wing shows the highest continuous grades in hornfels.
“West Wing also shows a notable copper signature.”
Nova will conduct airborne geophysical surveys which will commence in the northern spring of 2026.
NVA is up 5.88% to 90.0¢. Mkt cap $387.7M.
