Thanks, Jason. I'll now share some more details regarding our financial results for the third quarter ended March 31, 2021. Please refer to our press release from yesterday afternoon for additional information and details for the full fiscal third quarter '21 and look out for our Form 10-Q to be filed soon. Highlights for the third quarter are as follows. As Jason had mentioned, we paid our 30th consecutive quarterly cash dividend for common shares on March 31, 2021, and declared a $0.05 per share dividend for our fourth fiscal quarter payable on June 30, 2021, which is a 67% increase from the prior quarter. Also, as we had previously announced, actually yesterday that we closed on substantially all of our acquisition of the nonoperated oil and gas minerals and working interest in the Barnett shale for $18.2 million net of preliminary purchase price adjustments. I would add that this is just a preliminary purchase price, and we'll continue to adjust as additional cash flows are received as a result of the typical lag in revenues for nonoperated properties.
Total revenues increased 32% over the prior quarter to $7.6 million, and we generated cash flow in excess of the quarterly dividend and ended the quarter with $17 million in cash and no debt. I would also note that the $17 million in cash is net of a $2.3 million deposit we made last quarter for the Barnett acquisition.
Finally, we completed the spring redetermination of the credit facility and increase of borrowing base to $30 million. Also, this number does not include any impacts for our Barnett acquisition. The increase in total revenues by 32% for the quarter to $7.6 million from $5.8 million in the prior quarter is primarily due to a 38% increase in oil prices, which averaged $53.52 per barrel. Net production was down 5% this quarter to 1,708 BOE per day. As Jason mentioned, primarily due to the severe winter storm experienced at Delhi in February 2021.
However, if you adjust for the downtime we experienced at Delhi, average production would have been approximately 60 barrels per day higher for the quarter. Lease operating expenses increased 20% to $3.6 million in the second quarter compared to $3 million in the prior quarter. This increase is primarily due to an increase of $400,000 for purchase CO2, which represents a full quarter of CO2 purchases at Delhi as a purchase had just resumed in late October of 2020 after the pipeline repair.
Also contributing to the increase in purchased CO2 cost is a higher realized oil prices. And keep in mind that the CO2 cost at Delhi is driven by the price of oil. The remaining increase in lease operating costs of $200,000 was primarily due to an increase in the amount of workover activity by our operators in the current quarter. General and administrative expenses remained flat at $1.8 million as increases in acquisition-related legal and tax expense in the current quarter were offset by decreases from certain onetime consulting and legal expenses associated with the company's CFO services this past quarter.
To note, we incurred approximately $400,000 in onetime legal and tax expenses this quarter due to acquisition activity. We recorded an income tax benefit of $200,000 in the current quarter compared to a benefit of $3.2 million in the prior quarter, resulting in -- it was a 93% decrease or $3 million. This decrease is primarily attributable to the pretax loss of $15.9 million in the prior quarter due to the impairment that we took compared to a pretax income of $1 million in the current quarter.
Net income for the current quarter was $1.2 million or $0.04 per diluted share compared to a net loss of $12.7 million or $0.38 per diluted share in the previous quarter. Again, this increase of $13.9 million is driven by the noncash impairment that we recorded in the previous quarter. CapEx from maintenance and plugging activities was approximately $100,000 for this quarter. As we mentioned previously, conformance work has resumed at Delhi, and we expect this CapEx number to increase for the fourth quarter and full year 2022. We are currently estimating 250,000 to 500,000 for the fiscal fourth quarter and $1.25 to $2 million for fiscal year 2022.
As Jason mentioned, the majority of volumes shut in at Hamilton Dome during the low price conditions last year had been returned to production and future reactivations will be considered based on commodity pricing. There have been no updates to our reserves, and we continue discussions with Denbury and look forward to the development of Phase 5 at Delhi, which is still expected to begin in calendar year 2022 or 2023.
Working capital decreased by $1.5 million from the prior quarter to $20.1 million. This decrease is primarily attributable to the $2.3 million deposit previously mentioned that we made for the acquisition of the Barnett Shale assets. This deposit was applied to the adjusted closing price of $18.2 million. And we ended the quarter with $17 million in cash after paying out $1 million in dividends and continue to maintain an undrawn credit facility. Now this concludes our review of financial results and operations for our fiscal third quarter ended March 31.
I'll now turn the call back over to Jason for final remarks.
