Exploration Program
Rox has undertaken two drilling campaigns at Myrtle. Results are shown in the tables below.
These drilling programs have shown Myrtle to be a very large mineralised system that stretches over at least 3km east-west and 1km north-south (Figure 1).

Recently Rox discovered the Eastern Zone, which remains open along strike and down dip.

Importantly, the geological sequence at Myrtle is similiar to that found 20km north at the McArthur River deposit; the uppermost unit is the Reward Dolomite, which is underlain by the Barney Creek Formation (which includes the HYC Pyritic Shale and the W-Fold Shale), the footwall unit is the Teena Dolomite.
At Myrtle, and at McArthur River, base-metal (zinc and lead) mineralisation occurs within the HYC Pyritic Shale and the mineral bearing sequence occurs over an extensive area (Figure 2).
