MOD Resources is doing a JV with Oceana Gold at Sam's Creek, Nelson. Here's an article from NZReseources about the drilling equipment. Alton Drilling are also contractors to Glass Earth, and their helicoptered drilling platforms might come in handy at some stage. Noteworthy too, the reporter visited the site for the report.

Mod Resources gears up for busy year at Sams Creek

Ross Louthean — 24 February 2012
The Australian company that has taken charge of advancing exploration on the Sams Creek gold project near Takaka in the North West Nelson region is about to begin the last of its first phase nine-hole diamond drilling programme.
MOD Resources Ltd (ASX: MOD) is earning up to 80% equity on Sams Creek – the largest undeveloped gold deposit in New Zealand – from owner OceanaGold Corporation (ASX, NZX & TSX: OGC) by taking the project through to final feasibility study.
The Alton Drilling rig was completing the second last hole when NZResources.com visited the high-country site yesterday. Once the last hole of this campaign is completed, MOD Resources will begin planning a wider drilling programme aimed at lifting the established resource of more than 700,000 ounces gold, and significant silver.
The intent is to keep the Alton rig, built by its own factory near Auckland, on site and, by mid-year, evaluate whether to bring a second drill rig now being built by Alton at its workshops.
Some of Australia’s highly skilled drilling companies could learn some logistical lessons from the Kiwi operator, which has designed a rig that can be helicoptered into mountainous country where drill pads have to be cut, assemble and then rapidly disassemble and re-locate the rig to another location on another elevated drill pad.
Linked to this is an Alton-built camp that has been designed to perch in high country for around-the-clock drilling operators which can be moved within hours to be housed near a new drilling location, where man-made paths have to be cut.
By that time MOD Resources will be aiming to expand the resource picture at Sams Creek where the company already has plans to drill away from the Main Zone that holds the established resource, and to target lightly-explored areas by predecessors Rio Tinto and OceanaGold, for a project that has been virtually idle for more than seven years.
The known resource is within a 600m zone and managing director Derek Byrne said the programme through the balance of this year will be to sample or drill up to 600m on either side of Main Zone.
One of those targets will be Carapace, which sits above the Main Zone and takes in limited early drilling by Rio Tinto subsidiary CRA Exploration almost two decades ago where the first hole in the area produced a shallow hit of 9 metres grading 9 grams/tonne gold.
Because of its apex position, initial work at Carapace may take in sampling, using a hand-held drill for shallow probes and to use a modern saw technique to take rock samples.
MOD Resources, which also has a rapidly advancing copper discovery in the emerging Botswana copper belt, is building up its exploration team and is now providing jobs for New Zealand geologists and field operators, and has its administrative headquarters with Dunedin-based project manager Paul Angus, who spent many years in senior and administrative roles with OceanaGold.
