The following glossary from POW RNS to interpret the drill results at this stage may be useful:
Glossary:
· Serpentinite: a green coloured rock formed through the low-temperature metamorphism of ultramafic rocks from the earrth's mantle. The metamorphic chemical reactions convert unhydrous ferromagnesian silicate minerals (pyroxene, olivine) into hydrous silicate minerals (serpentine).
· Gabbroic: rock within the range classified as Gabbro which is a coarse-grained, mafic intrusive igneous rock formed from the slow cooling of magnesium-rich and iron-rich magma. Gabbro is found at the mid-ocean ridges and as plutons associated with continental volcanism. Gabbro intrusives can be associated with chromium, nickel, cobalt, gold, silver, platinum and copper mineralisation.
· Peridotitic: related to Peridotite rock, a dense, coarse-grained ultramafic igneous rock consisting mostly of the silicate minerals olivine and pyroxene. Peridotites is often a constituent in the layered igneous complexes that can host platiunum group metals and nickel.
· Ultramafic: Ultramafic rocks are a group of igneous and meta-igneous rocks with a very low silica content (less than 45%), generally >18% MgO, high FeO, low potassium, and are composed of usually greater than 90% mafic minerals (dark colored, high magnesium and iron content). The Earth's mantle is composed of ultramafic rocks. Intrusive ultramafic rocks are often found in large, layered ultramafic igneous intrusions where differentiated rock types often occur in layers and metals can be concentrated.
