And that brings us back to
politics. If those parties dedi-
cated to reducing regulations
gain strength, then the mining
industry could benefit – but if
politicians dedicated to continu-
ing the growth of governmental
intrusion gain strength, then seri-
ous problems for mining could
develop. It is that important.

drilling in an adjacent hole. The drilling
rates achieved by RoXplorer
®
in its first
full field trial provide us with confidence
that the $50/metre cost target is achievable.
THE HORSHAM TRIAL
DET CRC reported that the hole at
Horsham could not have been drilled
by reverse circulation (RC) methods and
believes the coiled tubing method is the
only cost-effective alternative to sonic or
mud rotary surface and diamond-tailed
holes in the highly prospective basement
sequences covered by the Murray Basin.
Reported results:
• The Horsham site provided the even
greater challenge of unconsolidated
Cenozoic cover overlying prospective
basement. The 135-metre cover sequence
included a lateral equivalent of the notori-
ously difficult to drill Loxton-Parilla sands
(~25-40 metres) and other unconsoli-
dated units overlying basement Cambrian
volcanics.
• The hole was rotary mud drilled to 42
metres and cased, then drilled with CT, a
downhole motor and blade bit and cased
to 140 metres (top basement). Drilling and
casing from surface to 140 metres took
three 12-hour shifts. The basement section
of the hole was then drilled from 140 to
407 metres in another three 12-hour shifts.
• A previous sonic/diamond hole at the
Horsham site was drilled to ~180 metres
at an average of 12 metres per shift.
RoXplorer
®
's hole averaged 42.5 metres
per shift including mobilisation and
demobilization.
Hillis stated in DET CRC's 2016-2017
annual report, "The launch, commission-
ing and successful trials of the RoXplorer
®
coiled tubing drill rig were the research
highlights of the year, indeed perhaps of
the lifetime of DET CRC."
