03/23/2012 (A Mckee) - Gold occurs in cm-scale quartz veins and associated with pyrite-pyrrhotite replacement mineralization. Sulphide mineralization is, in part, of replacement origin and typically occurs within wide intervals of strong silicification and brecciation. High grade gold mineralization appears to be focused along steep north to west trending structures that are internal or marginal to wide, lower grade breccia zones. (2.32536)

03/23/2012 (A Mckee) - 2005 drill hole NT-031 an interval grading 24.89 g/t Au over 3 m (including 69.02 g/t over 1 m) from a chert breccia with pyrrhotite and pyrite as disseminations, blebs, wisps, fragments, and minor stringers. Pyrite is 10-10%, pyrrhotite is 15-25% of the rock (Assessment report 20000001591). 2011: multiple assays returned from several drill holes best example NT-040 grading 14.23 g/t over 5 m including 61.2 g/t over 1m.
10/30/2020 (T Pettigrew) - Highlights of the 2013 drill program in the NE part of the Heath Bull Zone included 10.0 m grading 7.43 g/t gold, including 0.5 m of 128.0 g/t gold, and 6.0 m of 4.57 g/t gold including 0.5 m of 49.10 g/t gold (hole NT-162) (Bullis et al., 2015).
