The Molly B showing is located in outcrop on Gladwin Creek, 3.2 kilometres southeast of Gladwin.

Small local occurrences of malachite are found in shear zones within Triassic Mount Lytton Complex diorites and quartz diorites. Chlorite alteration of the intrusives is extensive. Pegmatite dykes cut intrusives. In one locality wide lenses of mineralized quartz is reported although no details are given (Meyer, 1969).

Areas of intense alteration were outlined by a magnetometer survey and scattered anomalies found from the soil survey. No other information is available.
