The production boost from 24 to 32 Mt/y will allow the company to take advantage of increases in the international iron ore market for its particular product -
pisolitic limonite sinter fines.
This is
pisolitic (rounded gravels), iron-enriched, dehydrated bauxite which is cemented into a hardcap layer in places.
Prior to chemical analysis, all soils were air-dried and sieved (<2 mm) to remove stones and
pisolitic bauxite.
The 100% owned Riley Iron Ore Mine (Riley DSO Hematite Project) is located 10 km from the Mount Lindsay Deposit and occurs as a hematite rich
pisolitic and cemented laterite.

The intact lateritic profile was mostly formed by weathering of granitoids and other rock types and these profiles commonly consist of sand and
pisolitic gravels over lateritic duricrust (cemented ferruginous material), mottled and pallid zones (quartz and clay rich materials), saprolite and saprock (isovolumetrically weathered materials with retention of parent rock fabric), and rock (Anand and Paine 2002).
The end product of latertization is generally
pisolitic ferrugenous laterite (Babu and Aseefa 1978).
Dolomite is found as small white rhombohedrons and
pisolitic masses.
The Eastport Formation in New Brunswick comprises amygdaloidal mafic flows and agglomerate, massive to flow-banded felsic flows, welded and non-welded lapilli tuff,
pisolitic tuff, peperitic breccia, and grey to maroon sandstone and conglomerate totalling ~4000 m (Hay 1967; Pickerill and Pajari 1976; Pickerill et al.
