Forum's mineral claims cover an approximate 18 km strike length of what is known as the Love Lake Igneous Complex
(including the Swan River Complex, Love Lake Pluton and other intrusive rocks).
Nickel-copper and platinum group metals ("PGM") bearing sulphide minerals occur in a 60 km by 27 km elliptical igneous body called the Sudbury Igneous Complex
* the Phalaborwa Igneous Complex
hosts extensive deposits of copper, phosphate, titanium, vermiculite, feldspar and zirconium ores
This is an uncommon occurrence in the region and demonstrates similarities with both the South Range Breccia Belt (SRBB) and footwall-type breccia that occur along the footwall of the Sudbury Igneous Complex
The study also stated lava flows, which surrounded the volcanoes known as the Bight Basin Igneous Complex
, were most probably created due to an eruption that occurred under the sea around 35 million years ago.
The Platreef project is located on the Northern Limb of South Africa's Bushveld igneous complex
. The DFS forecasts that the project will be Africa's lowest-cost producer of PGMs, with a cash cost of $351/oz of 3 PGMs + gold, net of byproducts and including sustaining capital costs.
All of the group's assets are situated in various locations across South Africa's Bushveld Igneous Complex
, which is the world's richest source of PG.
On a qualitative basis, they linked elevated dolomite Fe, Mn, and Zn concentrations with midocean ridge vent emissions derived from the Predazzo igneous complex
near the Latemar platform (Figure 1(b)).
"In reviewing the opportunity, our exploration team quickly recognized the significant potential for Ni-Cu-PGM mineralization on unexplored portions of the (Sudbury Igneous Complex
) basal contact and footwall of the property, which are not subject to the Lockerby Mine closure plan."
In this way we could judge whether the clasts were derived from a single igneous complex
or from unrelated intrusives.
Bye and Bell (2001) has studied the open pit with respect to the slope stability and described, "Sandsloot open pit is located on the northern limb of the Bushveld Igneous Complex
. It is the largest open pit platinum mine in the world.
The orebody runs along the eastern edge of the eastern limb of the mafic Bushveld Complex, an ancient igneous complex
over 2 billion years old.
