Mine Info

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Analytical Data

Analytical Data: 44.09-51.16% CR2O3, 13.6-26.5% FEO, 2.95-18.3% MGO, 6.0-8.6% SIO2, 9.2-11.10% AL2O3, CR/F=3.13. ASSAY VALUES FOR INDIVIDUAL CLAIMS GIVEN IN MOEN. CONE EQUIVALENTS OF ORE FROM DANNY, GOOD HOPE, AND RIBBON CLAIMS RANGED FROM 39-41. CALCINATION TESTS ON CHROMITE FROM DANNY CLAIM SHOWED THAT THERMAL EXPANSION WAS RAPID BETWEEN CONES 19 (1,520 DEG C) AND 26 (1,595 DEG C), THAT IT DECREASED TO CONE 30, AND THAT VOLUME REMAINED PRACTICALLY CONSTANT FROM CONE 30 (1,650 DEG C) TO CONE 40 (1,885 DEG C)
