operations may be carried out by either placer
mining or lode mining. Lode mining is also called
hard rock mining.

all gold is deposited in a lode or vein
filled with mineral in the rock, such as the gold-rich veins discovered
in Cow Mountain. When these lodes are disintegrated by natural erosion,
such as water flowing over the rock, placer gold is the result - the
deposit of loose surface soil or gravel that contains gold.
rare crystalline gold occurs in both the
placer streams and the lode deposits. Given the earlier success of placer
gold mines in the Cariboo, prospectors were obliged to search for the
local source of the placer gold in hidden lodes beneath the surface
of the earth.
of placer mining involves filling a pan with the crushed ore to separate
the gold. This could be done individually by one prospector on their
of lode mining involves the labour of many miners working together to
extract the gold from tunnels in a mountain or the earth.
gold mines were a success in the Cariboo Gold Rush and started up towns
like Barkerville, Richfield, Camerontown and Marysville during the 1860s.
like Fred Wells were compelled to search for the source of this placer
gold in the Cariboo - the 'Motherlode'. Coarse nuggets containing fragments
of vein quartz were discovered from Lowhee Creek and elsewhere so it
was probable there was a local source or lode where the placers originated
from, waiting to be discovered nearby.
