Sandstorm Gold Ltd. provides financing to gold mining companies through gold stream and royalty agreements. Stream and royalty finance involves Sandstorm making an upfront payment to a mining partner that is in need of capital to build their mine, refinance their obligations, complete an acquisition or for various other reasons. In exchange for that upfront payment, Sandstorm receives the right to purchase a percentage of the gold produced from the mine (in the case of a stream) or a portion of the revenue generated from the mine (in the case of a royalty). Since 2009, Sandstorm has compiled a portfolio of 250 streams and royalties, of which 40 of the underlying assets are currently producing.
