The Lou Dillon occurrence is located on a tributary, east of Silverton Creek and 2 kilometres west of Long Mountain. Silverton, British Columbia lies 12.5 kilometres to the northwest.

By 1935, the workings consisted of a lower crosscut adit 84 metres long and intersecting the lode at its face. The lode was drifted for 5.4 metres to the northeast and 22 metres to the southwest.

Hostrocks of the Lou Dillon occurrence are coarse grained porphyritic granite of the Middle Jurassic Nelson intrusions. Occasional fine grained biotite granite dikes crosscut the coarser granite.

Drifting has exposed a fault-fissure lode composed of brecciated wallrock and gouge cemented with interstitial quartz, siderite and lesser calcite. The lode strikes 045 degrees and dips 65 to 90 degrees southeast. At about 9 metres above the main crosscut, a 47.5 metre long drift exposed up to 1.9 metres of ribbon quartz with galena, sphalerite, pyrite and an unidentified silver-bearing mineral. The pyrite carries gold and silver.
