West African Resources (ASX:WAF) said it will increase the Burkina Faso government's free-carried equity in its Sanbrado, Kiaka, and Toega gold projects to 15% from 10% this year, in line with the country's new mining code, according to a filing with the Australian bourse on Wednesday.

Apart from the equity adjustment, all other terms of its existing agreements with the government will remain unchanged, the filing said.

WAF also confirmed its gold production guidance for the year of 190,000 ounces to 210,000 ounces at an all-in sustaining cost of less than $1,350 per ounce.
