INTRODUCTION The Duyan Gold Mine is located in the northeastern part of Persiaqued, 40 km east of Ruanda-Nolanda, northwestern Quebec (Figures 1 and 2). The first gold exploration in the Persian Gulf region was in the early 1960s. The Mick Mark Gold Mine (0.7 million tonnes of ore with a gold grade of 4.5 g / t) and the Moshra gold deposit (4400 tonnes of ore with a gold grade of 27.1 g / t) was first discovered in the 1930s Gold deposits (Figure 3). From February 1980, the ore was mined from an open pit mine. By February 1986, 5.1 million tonnes of mined ore had been produced, with a gold grade of 5.6 g / t and a total recovery of 26.5 tonnes.
