Newmont Waihi evaluates South and West Waihi permits22 May 2013
The community conscious miner Newmont Waihi Gold has detailed activity it has been undertaking on areas in Waihi with Glass Earth Gold Ltd (TSX-V and NZAS: GEL).
Newmont Waihi said Glass Earth Gold holds exploration permit 40767 which covers a predominantly residential area south and west of the Martha mine.
Newmont Waihi was conducting surveys on part of the permit where it can earn an interest by conducting work to an “agreed specified value.”
Once this value is reached Newmont Waihi can formalise a joint venture agreement.
There have been varying levels of interest in this area over the last 50 years with some drilling undertaken in the 1960s and other exploration since. Nothing of any interest has ever been identified.
Newmont Waihi Gold was currently undertaking gravity surveys in Waihi West that involves a technician with a roving monitor spending about 10 minutes beside the road at each location.
A gravity survey detects variations in the earth’s gravity field that indicate variable density of the rocks beneath the ground.
For example, Newmont Waihi said, the Waihi Basin - the flat land to the south of Waihi - is characterised by a large circular gravity low that indicates that that area was once a large caldera, similar to Lake Taupo. The gravity low indicates that the Waihi Basin is filled to considerable depth with volcanic deposits that have a much lower density than the surrounding hills.
There have been several gravity surveys carried out in the area previously, but they have not been evenly spaced. In some areas the survey points are close together and in other areas there is very little coverage.
Where the stations are closer together more detail is apparent in the resulting processed data. This new survey will ‘fill in the gaps’.
The current survey is attempting to improve the district-wide resolution to make it easier to interpret data. The copany said it was not expected the data will reveal details such as the presence of veins. It is aiming to assess whether some of the larger geological features interpreted from previous drilling can be detected through their gravity response.
“Our work in Waihi West is one part of the exploration programme Newmont Waihi Gold is engaged in as we continue to determine what, if any, areas should be considered for further investigation,” the company said.
“This is all part of the exploration process. It is lengthy and detailed, taking place over years rather than weeks or days. We are very used to acquiring what some may consider ‘discouraging’ results, but that is the nature of the activity.”
Newmont Waihi said that in the Waihi West area of the permit the exploration there was not related to the company’s Correnso discovery closer to the Martha mine.
“It is coincidental that the work in Waihi West was scheduled for this time. There is no connection between the Correnso announcement and the start of work in Waihi West.
“We have not identified an ore body under Waihi West despite conducting exploration activities including drilling since 2006.
“If the current exploration activities suggest there is merit in a closer look at the area we will employ other more precise techniques. At this stage, however, we have nothing to report other than routine investigations over a wide area.”
