The Noonday showing consists of quartz veins in andesitic volcanic rocks of the Upper Triassic Nicola Group. The principal working is an old incline shaft reported to be 30.5 metres deep but is caved at the collar. The shaft explored an auriferous quartz veins 15 to 46 centimetres wide, striking 140 degrees and dipping 75 degrees southwest. At the 30 metre level the veins come together and form a lode 1.5 metres wide. The veins contain some native gold.

The Noonday group was originally staked by O.S. Batchelor and associates. In 1899, development consisted of an incline shaft 30.5 metres deep; a drift at the 15 metre level extending 15 metres on the vein; a drift from the bottom of the shaft intersecting the vein, and a crosscut 9 metres long. In 1972, 14.5 kilometres of ground magnetometer and VLF-EM survey was completed on a portion of the Ramona claim group on behalf of Manor Mines Ltd. The claim group is reported to cover the showing.
