Meyn, p.57. | Southeast band 51m wide X 975 m long 24.29% soluble iron. Northeast band 31m wide X 762 m long 23.77% soluble iron. The best grade of iron formation averaged 26.2 to 26.4% acid soluble iron over 24m, in a section 52m wide and about 300 m long. Recovery was 87.5% using -200 mesh with the concentrate grading 63.0% Fe and 11.9% Si. | Iron 24.29 % |

1960 | 122 | The exposed parts of the iron formation are too small to be considered economic at the present time and the covered iron formation is uneconomic because it cannot compete with similar iron formation mined by open pit methods. The best grade of iron formation averaged 26.2 to 26.4% acid soluable iron over 24 m in a section 52 m wide and about 300m long. Recovery was 87.5% using -200 mesh with the concentrate grading 63.0% Fe and 11.9% silica. |
