The Areal target is located 21 km due south-west from the Aurizona Gold Mine (Figure 1). The Areal area was worked by artisanal miners in the 1980s, who extracted free-gold from quartz veins and colluvium. One flooded pit is located within the anomalous trend and numerous shallow surface diggings occur in the general vicinity. Luna conducted a geochemical survey followed by a ground magnetic survey and geologic mapping program, which has identified a 1.7 km long gold in soil anomaly within a northwest trending shear zone. Gold mineralization is associated with outcropping quartz veins and hydrothermal alteration and is coincident with a pronounced magnetic low that is associated with altered felsic intrusives within the shear corridor. The geophysical anomalies correlate well with the geologic mapping and importantly have identified a mafic volcanic footwall sequence providing a structural control to the mineralization. Gold shows certain correlation with molybdenum, bismuth and lead consistent with a shear hosted intrusive mineralizing system. Luna Gold’s geologists collected 303 reconnaissance rock chip and channel samples from across the Areal target with a maximum gold value of 1.60 grams of gold per tonne (g/t Au). A project grid has been established at Areal and a topographic survey completed for the target.
