Silver had first been discovered near Long Lake (later Cobalt Lake, Ontario), during the construction of the Temiskaming & Northern Ontario Railway (T&NO) from North Bay, by J. H. McKinley and Ernest Darragh, which then became the McKinley-Darragh Mine.Ministry of Trade and Commerce CHRONOLOGICAL RECORD OF CANADIAN MINING EVENTS FROM 1604 TO 1943, page 8.

Darragh and McKinley had made their find on August 7, 1903, while supplying railway ties, and kept it secret at the onset, while quickly filing their new claim on August 14.Davis, H. P.

A month later, La Rose, a blacksmith, unaware of the recent silver find, made his discovery while working for brothers Duncan and John McMartin, also in the construction of the T&NO, at Mile 103 from North Bay, where he'd built a small cabin. La Rose had an arrangement with the McMartins to share in any mineral claims that he found in the course of his work, and chanced upon Erythrite, often an indication of associated cobalt and native silver. (A fanciful story later developed that La Rose discovered the vein when he threw a hammer at a pesky fox.)

Mattawa, Ontario shopkeeper Noah Timmins was informed of the claim by La Rose who, at the end of his contract, had stopped at the Timmins brothers' general store while returning home to Hull, Quebec. Noah cabled his brother, Henry Timmins, who was in Montréal at the time and immediately set out for Hull, where he met with La Rose and offered him $3,500 for a quarter share of the claim, effectively partnering with the McMartin brothers.

La Rose was subsequently fully bought-out by the Timmins and McMartin brothers, who, following a protracted legal battle over the land with M.J. O'Brien,Nelles, H.V.

Metals discovered by La Rose and, previously, by the team of McKinley and Darragh, and then by Hébert, would spark international interest, culminating in the Cobalt silver rush. The LaRose Mine was closed in 1930, and the location became the main office of Agnico Eagle Mines Limited in Cobalt.Dumaresq, Charles Cobalt Mining Legacy, 2009. Retrieved May 3, 2018.
