According to the Crimea's Deputy Minister of Environment and Mineral Resources, Alexey Yatsenko, the region does not have a sufficient amount of crushed stone for implementation of projects under the federal programme.
Some four or five proven fields would be enough for Crimea to build high-quality roads.
The new fields are being found with much difficulty.
Small fields (with about 1 million tonnes of the resource) are located in conservation areas and forests, but it is noted that delivery of raw materials by sea increases construction cost.
