The Marlow showing is underlain by a section of metasedimentary rocks of the Upper Mississippian to Permian Milford Formation and Cambrian to Devonian Lardeau Group. Foliation has a general 290-to 330-degree strike, dipping 40 to 60 degrees northeast in the western part of the property and overturning in the centre of the property with dips of 45 to 70 degrees to the southwest in the eastern parts. The change in dip may in part be due to slumping and part due to an open parasitic fold related to a more regional major structure.

The Lardeau Group on the property consists of six rock units: unit 1 is a grey to white recrystallized limestone commonly banded, unit 2 is a clean white banded quartzite, unit 3 is a well foliated sericite chlorite phyllite to argillaceous phyllite, and unit 4 is a chlorite schist to massive amphibolite. Unit 5 is comprised of quartz feldspar argillaceous banded schist locally slightly chloritic and locally graphitic. Unit 6, a quartz feldspar biotite schist to a quartz feldspar sericite schist is gradational from what appears to be a highly altered unit 5. Areas of the quartz feldspar sericite schist are locally accompanied by molybdenite mineralization found as a fine dusting along with pyrite and often pyrrhotite. A biotite alteration halo is developed in the surrounding quartz argillaceous schist. The younger Milford Formation rocks of unit 7 unconformably overlie the Lardeau Group. However, due to tectonic activity the Lardeau rocks are now stratigraphically above the Milford rocks. Unit 7 consists of grey to black slates locally grading to silty sandstone and conglomerate. Unit 8 are intrusive dikes comprised of fine-grained quartz-eye monzonite to syenite and are evident within the Milford and Lardeau rocks commonly cutting the foliation at a small angle. The dikes are usually no more than 1 to 1.5 metres wide and often occur in swarms. The only mineralization observed in them are fine disseminations of pyrite and in one case a small amount of galena occurs.

The showing was staked in September 1977 by Noranda Exploration Company, Limited on the strength of a small molybdenite showing located during a 1977 regional silt and soil program. In October 1977, Noranda established a control grid and a soil survey completed. During June and July 1978 fill-in lines and soil sampling were done. In September 1978 a diamond drill program was performed totalling 277 metres of BQ drilling in three holes. The projected extension of the mineralized horizon was intersected in all three holes.
