The New Law occurrence is located 7.8 kilometres southeast of Metsantan Lake and 8.75 kilometres west-northwest of the Lawyers mine (094E 066), on the west side of Lawyers Creek, approximately 287 kilometres north of Smithers.

The New Law showing consists of a mineralized diabase to diorite dike hosted in a granodiorite stock, exposed on a northwest-trending ridge 6.3 kilometres northeast of Kadah Lake and 3.5 kilometres northwest of the confluence of New Law Creek and the Toodoggone River (Assessment Report 9995). It lies within the Omineca-Cassiar Mountains in the north-central portion of the Toodoggone Gold Camp.

The showing is situated within a Mesozoic volcanic arc assemblage which lies along the eastern margin of the Intermontane Belt, a northwest-trending belt of Paleozoic to Tertiary sediments, volcanics and intrusions bounded to the east by the Omineca Belt and to the west and southwest by the Sustut and Bowser basins.

Permian Asitka Group crystalline limestones are the oldest rocks exposed in the region. They are commonly in thrust contact with Upper Triassic Takla Group andesite flows and pyroclastic rocks. Takla volcanics have been intruded by the granodiorite to quartz monzonite Black Lake Suite of Early Jurassic age and are in turn unconformably overlain by or faulted against Lower Jurassic calcalkaline volcanics of the Toodoggone Formation (Hazelton Group).

The dominant structures in the area are steeply dipping faults which define a prominent regional northwest structural fabric trending 140 to 170 degrees. In turn, high angle, northeast-striking faults (approximately 060 degrees) appear to truncate and displace northwest-striking faults. Collectively, these faults form a boundary for variably rotated and tilted blocks underlain by monoclinal strata.

The New Law showing is underlain by volcanics of the Lower Jurassic Metsantan Member of the Toodoggone Formation. The Metsantan Member consists of trachyandesite flows with lesser lapilli tuff and lahar; minor volcanic sandstone and conglomerate (Bulletin 86). Where altered, which includes the New Law showing, these outcrops are characterized by orange and pink feldspar crystals, epidote, and pyrite. Quartz veinlets are also found in altered areas. Outcrops of the Attycelley Member of the Toodoggone formation are found nearby and consist of dacitic lithic crystal tuff, lapilli tuff, lahar, volcanic sandstone, local conglomeratic interbeds and minor marine wacke (Bulletin 86).

Numerous fault structures are found around the New Law showing. One set strikes 330 to 010 degrees and appears to be truncated by a major west to northwest structure.

Twenty rock samples were collected during the course of property exploration in 1987. Overall, the level of gold in the samples is low. However, sample NL-87-19, taken from an area of silicification and quartz veinlets within the Metsantan Member was anomalous in silver and copper. Assay results were 28.7 grams per tonne silver and 0.0288 per cent copper (Assessment Report 17288).
