Barrick Mining Corporation (B.US) is planning an initial public offering (IPO) for its North American gold assets as the Canadian mining company grapples with operational challenges and rising costs. The board of Barrick Mining has unanimously approved management's proposal to spin off a division through an IPO. The new entity will include Barrick's joint venture interests in Nevada Gold Mines and the Pueblo Viejo mine, as well as its wholly-owned Fourmile gold discovery project in Nevada. In a Monday statement, the company confirmed that only a minority stake will be offered in the IPO. Shares of Barrick Mining rose nearly 4% in pre-market trading on Monday.
