The story
Thomas Cruse, an Irish immigrant who prospected for years, struck it fabulously rich here with the Drumlummon Mine (named for his home parish), selling to English investors for a fortune that helped build Helena — including its cathedral. Marysville, named for the first woman resident, boomed to ~3,000 with railroads, churches, and an opera house in the 1880s-90s.
Epic Anglo-American litigation over apex mining rights, then declining ore, wound the district down by the 1920s. About eighty residents, a famous steakhouse, and streets of arrested-decay buildings remain — twenty minutes from Helena and one of Montana's easiest ghost visits.
What remains today
Brick and frame commercial blocks, churches, the rail depot, mine plants on the hill — a walkable mixed living/ghost townscape.
Questions from the field
- What was the Drumlummon Mine?
- Thomas Cruse's gold-silver bonanza, one of Montana's richest — its sale financed swaths of Helena, and its later Anglo-American lawsuits made mining-law history.
