A new LEGO City subtheme, LEGO Mining, is set to be released later this year and pictures of the upcoming sets have surfaced on Brickset!

4204 – The Mine
Two additional sets, 4200-Mining 4×4 and 4201-Loader and Tipper, are to be part of the lineup as well but their pictures have not yet become available. Expect to see LEGO Mining sets on store shelves this summer.
