North American market futures were pointing lower, while European and Asian futures were mixed at the time of writing.

Among the movers in Toronto, Vanstar Mining Resources (TSXV: VSR) gained 13.3% yesterday, taking its gains to about 152% year-to-date, after its partner Iamgold unveiled an initial 3.2 million ounce gold resource for the Nelligan joint venture in Quebec.

For its part, Iamgold (TSX: IMG) closed down about 0.45%.

Meanwhile Amerigo Resources (TSX: ARG) closed down 3.75%, having announced it had reached a new three-year collective agreement between the 208-member union and its Minera Valle Central operation in Chile.

The deal comes as workers in the biggest union at the world's largest copper mine, Escondida in Chile, were set to go on strike yesterday in solidarity with protests about social inequality in the country.

Among the majors, Freeport-McMoRan (NYSE: FCX) gained 1.1% in New York, Fresnillo (LSE: FRES) rose 3.34% in London and Anglo American (LSE: AAL) gained 1% after releasing better than expected third quarter results.

Finally, new producer Gold Road Resources (ASX: GOR) was a standout in midday trade, up 15.6%, following yesterday's quarterly results indicating 2019 gold production from its recently-started Gruyere joint venture mine in Western Australia would be at the upper end of guidance.
