The project in south-west Spain, which was delivered on budget but saw third-party delays delay the commissioning of a new concentrator plant, will now see tungsten shipments accelerate as the new works come on stream.
La Parilla has now moved into the commissioning phase, ramping-up towards large-scale tungsten and tin concentrate production and sales.
The stop-start nature of commissioning and testing only allowed the older existing concentrator to produce 29.3 tonnes of concentrate during the first half of the year.
In the six months to June, revenue was €293,000 and the loss for the period halved to €1.0mln.
Looking forward, W Resources aims to begin production at the Régua mine and processing plant in Portugal next year, and is looking at bringing in joint venture partners to help monetise the São Martinho gold discovery in the same country.
