[1] Suize left for San Francisco on a ship from LeHavre in 1850, along with a travelling companion named Francis Jaquart, whose ticket she had paid for.

[1] After landing in San Francisco, Suize headed to the town of Jackson in Northern California, 35 miles south of where gold had been discovered at Sutter's Mill.

[1][2][3] In order to mine for gold, Suize entered into a partnership "by handshake" with André Douet, a Charentais, who agreed to back her in return for reimbursement and some of the assets.

Suize caused quite a stir; a woman as head of a mining concession was already an exceptional case, but one day she appeared in trousers, solid miners' pants, because she was tired of wearing petticoats while digging in the middle of damp gravel.

So she reopened the hole, and, armed with two revolvers and a soup tureen full of pepper, sat down at the entrance to the tunnel, where she had had her bed carried.

Suize was relieved, but to put an end to it at once, she sent an official request to the authorities of Virginia City in order to obtain the right to wear pants.

In 1862, he returned to Thones with enough money to retire, where he spoke about his activities "in a disturbing country where the condemned are hung on a tree in the main square".

[1] Afterwards, she entered the wine making business, planting a variety of Zinfandel grapes of Hungarian origin, probably coming from the eastern United States.

[13] To publicize her products, she ran ads in the local newspapers, in which she sometimes referred to herself as Madame Marie Suize Pantalon or as "Mrs.

[1] La Patrie, a newspaper from Montreal, recounted the end of her life: “Her body worn out by work, her mind tired from worrying about business, she gradually felt her strength declining, and a year ago, she decided to retire to her ranch, in the hope of restoring her health.

[14] Her ranch was immediately transferred to her business investor and partner André Douet, but it took him ten years before he could sell it in 1902 to other French people, the Lintillacs.

[15][16] Susan G. Butruille, drawing from her book Women's Voices from the Mother Lode, created a show based on Marie Pantalon, which she presented in Thônes, France in 1999 and in several places in California and Oregon.

[17] Monique Fillion, honorary president of the Friends of the Val de Thônes, presented several multimedia conferences on Marie Suize.

In the early 21st century, the house built by Suize was the only building of that era that was still standing, because it was modeled after the chalets of the Val de Thônes.

[1] Because she died penniless, Marie Suize was not entitled to a stele in Saint Patrick's cemetery in Jackson, where she rested in an anonymous grave.

On July 14, 2004, for the 150th anniversary of the creation of Amador County, a tombstone was built 112 years after her death, as a tribute to Suize and her fight for women's rights in California.
