Queenstake’s First Quarter Results

Denver, Colorado — May 15, 2007 — Queenstake Resources Ltd. (TSX:QRL, AMEX:QEE, the “Company”) reported a net loss of $5.1 million for the first quarter of 2007. Cash flow from operations before working capital changes totaled $1.2 million for the first quarter of 2007. Cash and cash equivalents at March 31, 2007 were $3.3 million. All amounts in this news release are in US dollars, unless otherwise stated.

Gold production was 47,235 ounces for the first quarter of 2007, of which Jerritt Canyon ore produced 28,612 ounces and ore and carbon purchased from Newmont contributed 18,623 ounces. Cash operating costs per ounce of Jerritt Canyon ore were $535 per ounce for the 2007 first quarter. In the 2006 first quarter, gold production totaled 29,873 ounces solely from Jerritt Canyon ore, as there were temporary mill shut downs due to mechanical gear issues related to the ball mill.

Effective March 16, 2007, the Company and YGC Resources Ltd. (“YGC”) signed a definitive combination agreement to merge the companies to form Yukon-Nevada Gold Corporation (“Yukon-Nevada”). The combination is structured as a plan of arrangement whereby the Company will become a wholly-owned subsidiary of Yukon-Nevada. Shareholders of YGC will retain one common share of Yukon-Nevada for each share of YGC held, and shareholders of Queenstake will receive one common share of Yukon-Nevada for each 10 shares of Queenstake held. Completion of the business combination is subject to shareholder, court and regulatory approvals and other conditions precedent.

The respective shareholder meetings of the Company and YGC to consider and vote on the proposed combination are scheduled for May 18, 2007.

Financial & Operating Review

The Company reported a net loss of $5.1 million for the 2007 first quarter compared with a net loss of $5.8 million in the 2006 first quarter. Revenues of $30.6 million were generated from the sale of 47,445 ounces of gold at an average realized gold price of $644 per ounce, compared with the average market price of $650 for the quarter. The lower realized gold price reflected certain price protection covenants related to the Auramet secured bridge loan financing facility (“the Facility”) during the quarter. As of March 31, 2007, the Company had no forward sales commitments. The Company continues to sell its gold production at the spot price.

Cash operating costs of $535 per ounce from Jerritt Canyon ore for the first quarter of 2007 reflected seasonal ore-drying bottlenecks at the mill and the ongoing reduced mill processing capacity since the third quarter of 2006 in order to minimize the risk of further mill pinion and bull gear mechanical issues. (See more information about the new bull gear below.)

Cash operating costs during the first quarter were in line with the fourth quarter of 2007. This together with the higher realized gold price, compared to the fourth quarter of 2006, generated sufficient cash flow to continue to fund the ongoing operations at Jerritt Canyon and to reduce the December 31, 2006 trade payables and accrued liabilities by $2.8 million at the end of March 2007, excluding the $8 million from the Facility used to pay for the new evaporation pond.

As announced by the Company on May 1, 2007, the Company reached agreement with Auramet Trading LLC (“Auramet”) to extend the payment date of the $8 million Facility by one month, to June 29, 2007. The borrowed funds, less costs of the transaction, primarily paid the costs of the new evaporation pond at the Jerritt Canyon operations which was mandated by the Nevada Department of Environmental Protection (“NDEP”). The Company is pursuing reimbursement for such costs under its reclamation insurance policy with American International Specialty Lines Insurance Company, a subsidiary of AIG (“the Insurer”), but the timing and receipt of such reimbursement is uncertain. The matter has been referred to arbitration.

Depreciation and accretion charges were $5.1 million for the first quarter of 2007, compared with $3.1 million in the first quarter of 2006. The higher depreciation was due to the increase in stockpiled ore and work-in-process ore inventories during the year. Exploration expenses were $258,000 in the first quarter of 2007 compared with $200,000 in the prior year quarter. General and administrative costs were $1.0 million, similar to the prior year quarter. The Company invested $2.3 million in the Jerritt Canyon mines during the first quarter, compared with $8.2 million in the 2006 quarter, which was impacted by unforeseen costs for mill gear repairs. Significant capital investments during the quarter were in underground mine development and in purchasing and refurbishing plant and equipment.

At March 31, 2007, the Company had a working capital deficit of $12.9 million, primarily due to the increase in purchased ore stockpile inventories and decreased cash and cash equivalents. At the end of the first quarter, the Company was carrying $23.9 million in Newmont purchased ore inventory and loaded carbon. The Company estimated that there were approximately 9,500 ounces contained in the Jerritt Canyon ore stockpile and approximately 45,000 ounces in the Newmont purchased ore stockpile at the mill at the end of the first quarter.

Cash and cash equivalents were $3.3 million at March 31, 2007 with unsold gold inventory of $0.6 million compared with $0.3 million at December 31, 2006.

Operations Review

First quarter 2007 production from Jerritt Canyon was 28,612 ounces, excluding production from ore and carbon purchased from Newmont of 4,476 ounces and 14,147 ounces, respectively. During the fourth quarter of 2006, Jerritt Canyon started processing loaded carbon under an agreement with Newmont using existing excess capacity in the Jerritt Canyon carbon stripping circuit.

Total ore tons processed during the first quarter of 2007 was 210,212, lower than the fourth quarter of 2006 but higher than the first quarter of 2006. Processed ore tonnage and gold production for the first quarter of 2007 were impacted as the Company continued to run the mill at reduced capacity to minimize risk of further mill pinion and bull gear mechanical issues. The grade of Queenstake ore milled was 0.25 ounce of gold per ton (opt), similar to a year ago. However, the overall grade of all ores processed, including the lower grade ores from Newmont was 0.21 opt. During the first quarter, Jerritt Canyon mined 172,992 total tons, of which 120,160 tons were ore.

A new bull gear was fabricated and shipped from Australia in March 2007 and is expected to arrive on site soon. The bull gear change is scheduled for June 2007 coincident with the annual mill maintenance shutdown. It is planned that the mill will be down for approximately two weeks at the end of June to allow for all maintenance and change-out activities to be completed. During the mill shutdown, the mines will continue to produce at capacity and ore will be stockpiled adjacent to the mill. After the installation of the new bull gear, it is expected that the mill will ramp up its throughput to again operate at 100% capacity or at an annual rate of approximately 1.5 million tons during the latter part of 2007.

The table below summarizes production results for both Jerritt Canyon ore and ore purchased from Newmont.

Outlook

The Company expects to close the Queenstake-YGC business combination in the second quarter of 2007, subject to shareholder, court and regulatory approvals and other conditions precedent. Following completion of the merger, the new Board of Directors and management of Yukon-Nevada Gold Corporation will determine the production outlook, and exploration and capital investment expenditures, in order to deliver maximum value from the Jerritt Canyon operation and assets.

Queenstake Resources Ltd.’s principal asset is the wholly owned Jerritt Canyon gold operations in Nevada, which has produced over 7.5 million ounces of gold from open pit and underground mines since 1981. Current production at the property is from two underground mines. The Jerritt Canyon

District, which comprises 119 square miles (308 square kilometers) of geologically prospective ground controlled by Queenstake, represents one of the largest contiguous exploration properties in Nevada. In addition, Jerritt Canyon also has one of only three permitted roasting facilities in Nevada.
