We are an operator and developer of high-quality, low-cost metallurgical coal in central and southern West Virginia, southwestern Virginia, and southwestern Pennsylvania. We have a near-term development portfolio of four long-lived projects: Elk Creek, Berwind, RAM Mine and Knox Creek, which with our current cash and investments, expected net proceeds from this offering and projected cash flow from operations, will be fully financed through 2020. We believe each of these projects possesses geologic and logistical advantages that will make our coal among the lowest delivered-cost U.S. domestic metallurgical coal to a majority of our domestic target customer base, U.S.-based blast furnace steel mills and U.S.-based coke plants, as well as international metallurgical coal consumers.
We began initial commercial production of metallurgical coal in the first quarter of 2017. We expect this to result in annual production of 1.1 million clean tons of metallurgical coal in 2017, 2.8 million clean tons in 2018 and full production of 4.4 million clean tons in 2022. Additionally, we anticipate that the incidental production of thermal coal will generate up to 10% of our tons sold during 2017 and 2018, and we may consider increasing our thermal coal operations in the future. We believe that we will be able to take advantage of recent increases in U.S. and global benchmark metallurgical coal prices and intend to opportunistically increase the amount of our projected production that is directed to the export market to capture favorable differentials between domestic and global benchmark prices.
