In 1920, Novomeysky immigrated to Mandate Palestine and began using his Hebrew name, Moshe. He settled his family in Gedera, near Tel Aviv, and purchased some land on the Dead Sea's northern shore, near Jericho. Towards the end of 1922 he purchased rights to mine salt at Mount Sodom and sail on the sea from a Bethlehem Arab, along with some disused huts on the northern shore. He continued his pursuits by founding a company, "Jordan", to search for oil. In 1924 he founded the Palestine Mining Syndicate, and conducted more geological surveys of the Dead Sea with the British geologist George Stanfield Blake.
