Dec 07, 2005 (A Wilson) - The Alice Lake iron range is considered to be the metamorphosed continuation of the Magpie Iron Range and, along with the Magpie Iron Range, defines a minor fold structure on the south limb of the Centre Anticline. The relationships between rocks adjacent to the iron range are poorly understood. To the west, the rocks are intermediate to felsic breccias and to the east the rocks are intemediate to mafic in composition.
| Rock Type | Rank | Composition | Texture | Relationship | Magnetite Ironstone | 1 | Chert-Magnetite | Host |
|---|---|---|---|---|
| Breccia-unsubdivided | 2 | Intermediate To Felsic | Hanging Wall | |
| Mafic lava flow-unsubdivided | 3 | Mafic To Intermediate | Footwall |
Dec 07, 2005 (A Wilson) - The felsic breccias consist of fine-grained, angular to subrounded clasts within a fine-grained, chloritic and magnetite-rich matrix. On the east side of the iron formation the rocks are poorly exposed, but appear to consist of intermediate to mafic metavolcanic rocks on the northeast side and intermeiedate to felsic metavolcanics on the southeast side. The iron formation consists of fine- to medium-grained massive magnetite with minor to abundant pyrite. The iron range is interpreted to consist of 9 separate lenses.

Dec 07, 2005 (A Wilson) - Samples taken from the iron formation range in composition from 32.37% Fe, 20.35% Si, 4.9% S to 42.57% Fe, 15.80% Si, 7.74% S. Analysis of diamond drill core returned iron values ranging from 32.37% to 42.57% Fe and 15.80% to 20.35% Si.
