Liquidity	2. LIQUIDITY At December 31, 2016, the Company had a working capital deficit of $4.3 million as compared with a working capital deficit of $8.9 million as of December 31, 2015. The decrease in the working capital deficit of $4.6 million was primarily due to an increase in cash and cash equivalents of $2.4 million and an aggregate decrease in accounts payable and accrued liabilities of $2.0 million. The increase in cash and cash equivalents and the decrease in accounts payable and accrued liabilities are due to the Company’s fundraising efforts during 2016, which included the completion of registered direct offerings on April 4, 2016 and February 4, 2016 for net proceeds of $1.2 million and $0.8 million, respectively, $6.7 million in net proceeds from the sale of common stock to Aspire Capital under the terms of the CSPA and $5.8 million in net proceeds from the sale of common stock sold through the Company’s at-the-market sales program. Subsequent to December 31, 2016, the Company received $2.2 million upon the completion of the sale of its wholly-owned subsidiary Hydro Resources, Inc to Laramide on January 5, 2017 and received an aggregate $13.4 million upon completion of a public offering on January 19, 2017 and a registered direct offering on February 16, 2017. In addition, the Company repaid the remaining $5.5 million outstanding under the RCF Loan on February 9, 2017. As a result of the above, the Company’s cash balances were $10.4 million at February 28, 2017, which the Company expects will provide it the necessary liquidity through the first quarter of 2018.
