There was plenty of mining news on the day.
Klondex Mines Ltd (NYSE:KLDX, TSE:KDX) has repeated its production guidance for 2017 of between 210,000 to 225,000 gold equivalent ounces, as it posted what it called 'solid' first quarter operating results.
The firm said output will be more heavily weighted in the second half as the True North mine in Manitoba, Canada and Hollister in Nevada, USA, continue to ramp up towards full output.
In the three months to end March, the group mined 57,633 gold equivalent ounces, which was in line with its expectations, it revealed.
It sold 33,737 gold equivalent ounces in the period, 29,559 ounces of which were gold.
Elsewhere, metals explorer Gold Resource Corporation (NYSE:GORO) has told investors that gold production increased in the first quarter of the year.
US oil titan ConocoPhillips (NYSE:COP) reported on Wednesday a potential expansion to its Darwin liquefied natural gas (LNG) plant in Australia.
The energy group has launched a study to assess the merits of a multibillion-dollar expansion to the operation in Australia’s Northern Territory.
It comes amid a reported rise in domestic gas prices in eastern Australia and fears of a supply shortage but is a shift away from the firm's previous thinking about the area.
Tango Mining Ltd (CVE:TGV) revealed it had closed its agreement with Georges Zard, owner of conglomerate the GZA Group, over his purchase of a stake in the Oena alluvial diamond mine in South Africa.
Zard acquired from Tango an 8% interest in African Star Minerals, which owns 100% of the Oena diamond mine.
The mine consists of an 8,800-hectare converted mining right (CMR) on the lower Orange River, Northern Cape province, South Africa.
An application for a nine year renewal of the CMR is pending. The transfer of the 8% interest to Zard is subject to South African regulatory consents and approvals required to implement the transaction.
Tango received from Zard US$35,000 for the 8% stake in ASM.
Tango has placed in escrow around 3.245mln shares as security for Zard's interest in ASM to be held while the CMR is being renewed, which will be cancelled and returned to treasury upon renewal.
