W Resources PLC (LON:WRES) has highlighted a consolidation of recoveries from its La Parrilla tungsten and tin project in Spain in its fourth quarter to date as a result of ongoing plant improvements at the site.
In an update on its fourth quarter progress, the AIM-listed mining firm said its has achieved record recovery rates in November of 40% tungsten trioxide (WO3) and 53% tin (Sn), while mine grades were “consistently exceeding” 1,050 parts per million (ppm) WO3 and 350ppm Sn, which it said is “significantly greater” than the preceding three quarters.
The company added that its plant utilisation remains above 90%, which it said is encouraging noting its move to a four-day working week on November 4.
The group added that tungsten and tin concentrate production to date has exceeded the total production for the third quarter of 77.6 tonnes and that as recoveries and production improves plans are in place to move to a five day work week with “minimal closure” over Christmas.
Three 20 tonne shipments of tungsten concentrate have also been completed to date with further shipments planned.
“Following the improvements that led to such a strong September, I am greatly encouraged that this momentum has continued into [the fourth quarter]”, La Parilla’s managing director Pablo Neira said in a statement.
“These significant plant improvements together with accessing higher grade portions of the ore body are enabling us to build production rates each month as we work to increase concentrate production. We look forward to updating the market with the [fourth quarter] production update in January”, he added.
