Northern Lights Resources Corp announced the results of the airborne geophysics surveys at the Company's Secret Pass Gold Project located in Mohave County, northwestern Arizona. The airborne geophysics surveys are part of the Company's Phase 1 exploration program for the Project announced on February 10, 2020. MWH Geo-surveys International Inc of Reno Nevada were commissioned by Northern Lights to undertake digital photography, Digital Surface Model and magnetic surveys of the project area using UAV drone aircraft. The surveys were completed in two sorties in May and July 2020. The southern anomalies, M-05 and M-06 are considered the highest priority and show a close relationship with the Frisco Fault. The northern anomalies are associated with west-northwest riedel structures developed between the Frisco and Union Pass Faults. These structures have controlled the emplacement of Tertiary felsic dykes that often host both disseminated and vein controlled gold mineralization. Fault related, magnetite destructive alteration is commonly associated with gold mineralization at Secret Pass. The alteration comprises an assemblage of chlorite-sericite-clay-silica +- adularia and is expressed by strong magnetic lows. This type of alteration is well exposed in outcrop along the Frisco Fault and observed in drill holes at the Tin Cup and FM prospects.

The geophysical interpretation results show five key observations that are significant with respect to the potential for gold mineralization at Secret Pass.

1. The host rocks in the Secret Pass area have a low magnetic response. Epithermal alteration associated with gold mineralization in the Oatman Gold District is exclusively magnetite-destructive.

2. The Frisco Mine Fault has a distinct magnetic response manifested by a strong susceptibility low at the FM prospect. This magnetic low developed at anomalies M-05 and M-06, can be traced for approximately 1200 meters and is confined to the Tertiary andesite and basalt units.

3. The FM gold zone is located at a higher elevation compared to Tin Cup. Based on the Oatman model, the FM zone could have potential for high grade gold mineralization developed in boiling zones located below the limits of the historical shallow drilling.

4. At Tin Cup, the gold mineralization is related to a weak magnetic high which appears to reflect the propylitically altered andesitic host rock. This alteration feature is thought to represent the deeper, higher temperature roots of the Oatman epithermal gold model.
