This is an extract from a 2010 report of which MH was a part. A fluke?

"Exploration History.
The gold potential of the area around DeGrussa was first highlighted by a regional soil and shallow vacuum drilling program carried out between 2004 and 2007. A single line of shallow RAB drillholes was drilled in December 2007 after the vacuum drilling program had returned a 96 ppb Au bedrock sample. This drilling defined a sequence of saprolitic clay and sheared volcaniclastic sediments about 200m to the
south of the anomalous vacuum drill‐hole sample, and returned a 10m gold intersection with an average grade of 5.67g/t.

A second round of RAB drilling in April–May 2008 was focused around the identified shear zone and returned higher and more consistent Au grades. A third round of RAB drilling in July 2008 returned more exciting Au grades over a strike length of more than 100m.

Multi‐element analysis geochemistry was carried out on selected mineralised and un‐mineralised samples in early 2009 and, with the exception of Ni, all of the analysed elements were elevated against background levels (Tables 1 and 2), which indicated the potential for a polymetallic deposit in the area.

(Table deleted as indecipherable, but see the linked report for details, as well as other stuff from this 2010 paper)

A sub‐audio magnetic (SAM) and ground magnetic survey was carried out over the area in early 2009, neither of which showed any indication of a world‐class VMS deposit.

A follow‐up RC drilling program was carried out in May 2009 over the anomalous Au zone delineated by the previous RAB drilling program. Toward the end of the drilling program, hole DGRC‐083 intersected a significant gold intersection (19m @ 4.2 g/t) from a depth of 40m. A second, deeper hole (DGRC‐101) was drilled nearby to a depth of 144 m and intersected significant massive Cu–Au sulphide mineralisation below the zone of oxidisation (DeGrussa massive sulphide mineralisation). A further five RC holes were drilled, all of which intersected significant intervals of high Au grades, and a second hole that intersected the DeGrussa massive sulphide zone. At this stage, very little was known about the geometry or size of the discovery."
