As more fully described under Item 1, Business, in our Annual Report on Form 10-K for Fiscal 2024, we were incorporated under the laws of the State of Nevada on May 16, 2003 and, since 2004, we have been primarily engaged in uranium mining and related activities, including exploration, pre-extraction, extraction and processing, on projects located in the United States, Canada and the Republic of Paraguay. In November 2010, we commenced uranium extraction for the first time at our Palangana Mine utilizing ISR methods and processed those materials at our Hobson Processing Facility into drums of U3O8. We also hold uranium projects in various stages of exploration and pre-extraction in the States of Arizona, Colorado, New Mexico, Texas and Wyoming, in Canada and the Republic of Paraguay. In August 2024, we restarted uranium extraction at our fully permitted, and past producing, Christensen Ranch Mine ISR operation in Wyoming. We expect the ramp-up phase will continue while new production areas are being constructed and completed in 2025.
As more fully described under "Liquidity and Capital Resources" of Item 2, Management's Discussion and Analysis of Financial Condition and Result of Operations, herein, we have a history of significant negative cash flow and net losses, with an accumulated deficit balance of $349.29 million as of January 31, 2025. Historically, we have been reliant primarily on equity financings from the sale of our common stock in order to fund our operations. Although we generated revenues from sales of U3O8 we extracted during Fiscal 2015, Fiscal 2013 and Fiscal 2012 of $3.08 million, $9.03 million and $13.76 million, respectively, and generated revenues from sales of purchased uranium inventory totaling $66.84 million during the six months ended January 31, 2025 , we have yet to achieve consistent profitability or develop consistent positive cash flow from our operations, and we do not expect to achieve consistent profitability or develop consistent positive cash flow from operations in the near term. As a result of our limited financial and operating history, including our significant negative cash flow from operations and net losses to date, it may be difficult to evaluate our future performance.
As at January 31, 2025, we had working capital (current assets less current liabilities) of $126.45 million including cash and cash equivalents of $61.51 million and purchased uranium inventory holdings of $72.90 million. Subsequent to January 31, 2025, we received additional net cash proceeds of $2.04 million under our 2024 ATM Offering. We believe that our existing cash resources and, if necessary, cash generated from the sale of the Company's liquid assets, will provide sufficient funds to carry out our planned operations for 12 months from the date of this Quarterly Report. Our continuation as a going concern for a period beyond those 12 months will be dependent upon our ability to obtain adequate additional financing, as our operations are capital intensive and future capital expenditures are expected to be substantial. Our continued operations, including the recoverability of the carrying values of our assets, are dependent ultimately on our ability to achieve and maintain profitability and positive cash flow from our operations.
Our reliance on equity and debt financings is expected to continue for the foreseeable future, and their availability whenever such additional financing is required will be dependent on many factors beyond our control and including, but not limited to, the market price of uranium, the continuing public support of nuclear power as a viable source of electrical generation, the volatility in the global financial markets affecting our stock price and the status of the worldwide economy, any one of which may cause significant challenges in our ability to access additional financing, including access to the equity and credit markets. We may also be required to seek other forms of financing, such as asset divestitures or joint venture arrangements, to continue advancing our projects which would depend entirely on finding a suitable third party willing to enter into such an arrangement, typically involving an assignment of a percentage interest in the mineral project.
Our long-term success, including the recoverability of the carrying values of our assets and our ability to acquire additional uranium projects and continue with exploration and pre-extraction activities and mining activities on our existing uranium projects, will depend ultimately on our ability to achieve and maintain profitability and positive cash flow from our operations by establishing ore bodies that contain commercially recoverable uranium and to develop these into profitable mining activities. The economic viability of our mining activities, including the expected duration and profitability of our ISR Mines and of any future satellite ISR mines, such as our Burke Hollow and Goliad Projects located within the South Texas Uranium Belt, our Christensen Ranch Mine and Reno Creek Project located in the Powder River Basin, Wyoming, and our projects in Canada and in the Republic of Paraguay, have many risks and uncertainties. These include, but are not limited to: (i) a significant, prolonged decrease in the market price of uranium; (ii) difficulty in marketing and/or selling uranium concentrates; (iii) significantly higher than expected capital costs to construct a mine and/or processing plant; (iv) significantly higher than expected extraction costs; (v) significantly lower than expected mineral extraction; (vi) significant delays, reductions or stoppages of uranium extraction activities; and (vii) the introduction of significantly more stringent regulatory laws and regulations. Our mining activities may change as a result of any one or more of these risks and uncertainties and there is no assurance that any ore body that we extract mineralized materials from will result in achieving and maintaining profitability and developing positive cash flow.
