Miller Lake is approximately 14 kilometers from Goldenville with historic production, and limited recent exploration. Gold was discovered in a large quartz boulder in the area of Miller Lake by a Mr. R W Naugler around 1900. This gold bearing boulder subsequently led to the discovery of a vein that now bears the name of the original finder. By 1902, the Liscomb Falls Gold Mining Company had opened shafts on the Mill Lead and a 5-stamp mill was erected.
Miller Lake Highlights & Future Plans
- Two small historic shafts, with strike length over 1km
- Anticline similar to other Meguma deposits, along strike from Dufferin Mine (recently acquired by Resource Capital Gold)
- Follow up in 1988 consisted of geophysics and 2,377m of diamond drilling
- Detailed evaluation, target generation, & further reconnaissance and field work
|Year||Rock Crushed in Tons||Yield of Gold in Ounces|

Historic production figures from a Nova Scotia Department of Mines report
The Miller Lake Gold District consists of two main historic mining sites located in western Guysborough County, Nova Scotia, approximately 10km north of the village of Ecum Secum. This small fishing village on Highway #7 lies about halfway between the towns of Sheet Harbour and Sherbrooke.
Resources Appalaches held the property from 2000 until 2015 and undertook exploration programs and a comprehensive ground magnetometer survey of the property. This was their second property after the recently operational nearby Dufferin Mine and was explored with the intention to provide feed to the Dufferin mill.
After the discovery by Mr. R W Naugler in 1900, further exploration and trenching throughout the district resulted in several other veins being discovered, some of which went into production intermittently until the 1940’s. The Mill Lead is found in the south-central portion of the district and comprises the first reported workings. The most substantial workings are found in the eastern portion of the district where the Sweet Shaft and Boak Shaft both access the Lone Cloud Lead.
In 1983, Outland Resources explored the district and carried out geophysical and geochemical surveys with several trends identified. The following year, Acadia Mineral Ventures took over the exploration program and carried out further soil sampling in the anomalous areas defined by the Outland programs. In addition, panned concentrates from glacial till and stream sediment samples were taken in areas of anomalous geochemical response for Au and As defined from the previous year’s geochemical surveys. A 10 hole diamond-drill program followed (592 m) in the area east of Miller Lake and on both limbs of the northeast-trending Gegogan Anticline that passes through that area. This program identified the location of the Lone Cloud Lead in that area and visible gold was noted in the core.
In the late 1980’s two companies mounted substantial exploration programs at Miller Lake. The western portion of the district was explored by Seabright Exploration, and NovaGold Resources explored the eastern portion. Both programs consisted of substantial trenching, geological mapping, diamond-drilling and geophysical surveys with Seabright drilling 15 holes (1076 m) and NovaGold drilling 9 holes (1301 m).
Geology and Mineralization
Auriferous quartz veins at Miller Lake are stratabound and occur on both flanks of the east-trending, Gegogan Harbour Anticline. For the most part, the veins are within a few hundred metres of the anticlinal axis. On the north side of the anticline, the strata and veins dip north between 45-58°, while on the south limb the dips are 50-75° south. The Gegogan Harbour Anticline in the Miller Lake area forms a dome plunging to the east and west.
The quartz veins vary from a few centimeters up to 30 cm thick and Faribault (1903) reported that a few auriferous rolls occur up to 45 cm thick. The rolls dip east and coincide with the pitch of the anticline. The principal leads in the district are the Lone Cloud and Naugler leads on the north limb of the fold and the Mill and Maria Snow leads on the south limb. Rich drift has been reported along the entire length of the anticline through the district.
Most of the mining has been concentrated on the Lone Cloud Lead which has been worked from several shafts and is auriferous for a minimum strike length of 1097 m. The Boak Shaft was sunk to a depth of 32 m with the last 9 m of the vein containing quartz heavily mineralized with sphalerite, galena and arsenopyrite. The Lone Cloud Shaft, at the western end of the district, is also on the vein by that name and is 21 m deep. The vein averages 25 cm thick and is well mineralized with arsenopyrite and galena. Sights of Au are frequent.
