Evaluation of Pilbara antimony-gold potential generates positive results

HIGHLIGHTS

• Novo has conducted an evaluation of the antimony (Sb) – gold (Ouch) potential of its Pilbara land assets, in light of recent global changes in strategic metals supplies.
• Two prospects in the early stages of exploration score highly for antimony potential, including the historic Sherlock Crossing (Clarke) antimony mine and the
  South East Wyloo Antimony-gold flow sediment anomaly.
• The Sherlock Crossing antimony mine was discovered in 1906 and operated from 1907 to 1916.¹Novo conducted exploration work, collected rock fragment samples and collected soil samples at Sherlock Crossing in 2022, with peak results of 1.71 g/t Au and 592 ppm Sb.
• Southeast Wyloo includes two 2 km streaks of high order Sb (± Au) stream sediment anomalieswhere the exploratory sampling of rock fragments, which Novo carried out in mid-2023, yielded the best results of 387 g/t Ag, 5.0% Pb, 1.6% Zn, 2.4% Cu, 0.38% Sb and 0.52 g/t Au.
• Both projects are promising targets and require detailed follow-up exploration.
