PLAMAN Global holds several permits in the South Island of New Zealand. The Foulden Hills project is located in the Otago region of the South Island of New Zealand.

The deposit that is located at Foulden Hills contains a significant reserve of high quality black diatomaceous earth that can be recovered by open pit quarrying. Diatomaceous earth was first discovered at Foulden Hills by gold prospectors in the early 1870’s and the resource has been subject to a number of investigations since that time.

Following the completion of the acquisition of the mining permit and freehold land on which the mining permit sits, PLAMAN Global undertook extensive drilling campaigns in late 2015 and 2017, both of which led to a significant increase in the estimated size of the black diatomaceous earth deposit at Foulden Hills.


PLAMAN Global is dedicated to the safe and responsible extraction and use of the mineral resource that respects historical, cultural and environmental aspects of all areas in which we operate. The Foulden Hills project has been designed to comply with international best practice standards as well as New Zealand environmental legislation. Considering this, site specific environmental management plans will be prepared and an Environmental Manager role will be staffed at the quarry site.

PLAMAN Global has elected to use an offsite location for processing that is within an industrial zone. This will mitigate the environmental impact at Foulden Hills.


At PLAMAN Global, we are committed to being an approachable and socially responsible neighbour who shares the benefits of our projects with stakeholders within the communities in which we operate.
