Soil sampling, mapping and rock chip sampling in the Mt Goma area has delineated a mafic ultramafic complex. Within this complex a strongly weathered zone of approximately 700m by 200m has been defined with 200m by 50m pXRF soil sampling returning between 0.5% and 1.9% nickel.
25m by 25m, and 50m by 50m infill sampling has highlighted zones within the original 200m by 50m soil anomaly greater than 1% Ni with a peak result of 4.5% Ni (Figure 1). The association is most likely that of a lateritized ultramafic with elevated copper values generally adjacent to the nickel anomaly. Some elevated copper values up to 230ppm lie within the plus 1000pm Ni contour (Figure 2).
The Environmental Impact Study report was received and submitted to the regional government for approval and recommendation. An approval recommendation was received from the DGSM on the 18th of November 2015 which allows road clearance and drill access. Gravity surveying has been undertaken in 2018 with a view to defining targets for drilling.

One rock chip was assayed at the laboratory in addition to the many of anomalous rocks assayed by spot XRF. The rock chip returned a result of 2.64% Ni with the presence of garnierite (a common oxidised nickeliferous mineral) identified (Figure 3).
