The Good Hope occurrence is located on Huckleberry Creek 5 kilometres northeast of Ymir. The claims were Crown granted between 1900 and 1905. Exploration was primarily done by the Ymir-Good Hope Mining Co. on the X-ray, Wild Horse and Annie Maud Crown Grants.

The area is underlain by slate, shale, argillite, limestone, quartzites, and their contact metamorphosed equivalents, of the Lower Jurassic Ymir Group. The metamorphic rocks consist of mica schists, graphitic schists, andalusite-mica schists, biotite schists, talc schists and paragneissic rocks. These have been intruded by porphyritic granite and dykes and sills ranging in composition from aplite to lamprophyre of the Middle to Late Jurassic Nelson Intrusions. Silicification of the sediments in contact with the granite intrusions is common.

The showing consists of a number of parallel shear-related quartz veins hosted by argillite and schist which strike north with moderate to steep west dips. The quartz veins parallel the foliation and bedding of the sediments. Granite is observed to form the footwall of the main vein. Individual veins are up to about 0.60 metre wide but are usually 0.15 to 0.30 metre wide. The veins are discontinuous and locally occur as a sort of quartz stockwork or reticulating quartz veinlets within zones of brecciated sediments or granite. Fault gouge is common.

Mineralization is sporadic but consists mainly of pyrite, minor pyrrhotite, sphalerite, galena and minor chalcopyrite within a blue to white quartz gangue. Quartz gangue is most common but siderite is locally associated with sphalerite.

Metal values are low and sporadic although selected grab samples have contained as high as 90 to 100 grams per tonne gold (Geological Survey of Canada Paper 51-4). Minor cadmium, silver and zinc values are also present. Minor production totalling 41 tonnes yielding 902 grams of gold and 3,950 grams of silver is reported for this occurrence.
