Yes. We were talking about Tantahuatay. I think that was the last that we mentioned. We -- our gold production for the fourth quarter of 2014 increased 15% compared to the figure of 2013. Cost applicable to sales increased 24% due to higher consumption of reagent and blastings applied due to higher stripping ratio. Our gold production guidance for Tantahuatay is similar to La Zanja in the order of 140,000 ounces of gold.
In El Brocal, where we control 54% of the equity, during the fourth quarter 2014, zinc production increased 100% compared to the 2013, due to higher volume treated from the Tajo Norte polymetallic copper production increased 15% compared to the same quarter of 2013. Silver production increased 57%. And the cost applicable to sales, 13% compared to -- increased 13% compared to the same quarter of 2013, due to higher commercial deduction in the zinc -- and zinc cost applicable to sales increased 5%. Zinc production guidance for 2015 is in the order of 80,000 tons of zinc, and copper production guidance is in the order of 35,000 tons of copper.
In terms of our exploration in non-operating areas. Non-operating areas during the fourth quarter was $17.8 million compared to $9.4 million in the fourth quarter of 2013.

Despite of the fact that Yanacocha reported $80.6 million of net income under U.S. GAAP, the impact of an impairment loss in accordance to IFRS related to Conga, resulted in a loss of $380 million. And in the fourth quarter of 2014, costs applicable to sales was $426 per ounce, an increase of -- a decrease of 50% when compared to $849 per ounce in the same quarter of 2013, due to lower stripping ratio in accordance with the mining plan.
