The 3,000-metre aircore drilling program will test several coincident gold-in-soil, aeromagnetic and gravity anomalies.
Drilling is expected to be completed within two weeks, with assay results expected by the end of May.
Arrow carried out detailed pre-drilling exploration Strickland in 2018 including soil sampling, magnetic surveys, gravity surveys and mapping.
A strategic review of this data has highlighted the Helsinki prospect as the highest priority target yet to be drilled.
Specifically, the gravity survey has identified a 5 kilometre-long intrusion, with a large, coherent gold-in-soil anomaly along the intrusion boundaries.
As per below, the aircore drilling program will consist of seven regional traverses for 50-60 holes.
The program is designed to identify the position of potentially mineralised structures for follow up drill testing in the June quarter of 2019.
