Ann: Final Assays & Structural Report Confirm Mawson Discovery, page-41

Conductor D5D5 is a high priority conductor given its close proximity to aircore drillhole RKAC183, which intersected disseminated pyrrhotite-pentlandite-chalcopyrite in a **bronorite host rock. RKAC183 previously returned the significant assay result of: 14m @ 0.37% Ni, 0.43% Cu, 0.03% Co from 72m to end of hole, including 2m @ 0.46% Ni, 1.44% Cu, 0.04% Co from 77m (ASX announcement 9 April 2018).The D5 conductor has been remodelled incorporating recent infill data and defined a large (1,000m x 1,500m) feature with moderate conductance of 1,500-2,500S and a depth to top of conductor of 125-175m. Significantly, the modelled top of the conductor lies 200m to the west of aircore drillhole RKAC183 with the ~800 ESE dip indicating the conductor extends below RKAC183.

The above may clear a few things up for you

Note the current drilling is targeting the D5 conductor, identified by MLEM .. estimated depth to top of conductor 125-175 m .. so this is all stacking up here

I believe the modelling of the D5 conductor would still supercede DHEM from 005-007

Tells me the top of the conductor is what they are chasing though
