Queenstake boosts economics of Magistral project Queenstake Resources Ltd (2) QRL Shares issued 58,222,954 Jun 3 close $0.33 Tue 4 Jun 2002 News Release Mr. Chris Davie reports MAGISTRAL GOLD RESOURCES INCREASED BY 21%, RESERVES BY 26% Queenstake Resources has reported results of the updated calculation of the gold resources and reserves at its 50-per-cent-owned Magistral property in Sinaloa, Mexico. The updated calculation, performed by Pincock Allen and Holt (PAH) of Denver, was based on extensive drilling on the La Prieta zone in the Samaniego Hill area carried out since September, 2001, and reported in news release NR2002-4. The reported resources also reflect a change in modelling software as the model has been transferred to Mintec's Medsystem for future use at the mine site. Resources are classified in five areas corresponding to four discrete mineralized zones and an old tailings pile. It is anticipated that the mineralized zones will be mined in four separate pits, known as San Rafael, Samaniego, Sagrado Corazon and Lupita. PAH reports the updated resources by zone as follows: Resources reported by PAH at a cutoff grade of 0.4 gram per tonne are tabulated as follows:

Using these gold resources as a base PAH has redesigned the Samaniego open pit in order to derive a new reserve for that zone. Some minor redesign of the San Rafael pit has also been undertaken, although the block model for this zone has not changed. The resulting reserves are tabulated below. For completeness, the Sagrado Corazon and Lupita reserves are included, although the block models and mine designs have not changed. There are some minor differences relative to the feasibility study due to changes in software used. The tailings in the Samaniego area have been included in the Samaniego reserve estimate. Proven and probable gold ore reserves determined by PAH are as follows:
Area Gold cut- Tonnes Grade off grade 1,000s gpt gold gpt San Rafael 0.40 1,324 2.24
Samaniego Hill 0.42 4,077 2.28

It will be noted that most of the additional resources defined in the Samaniego area have also become reserves; the geometry of the high-grade zone now at the bottom of the newly designed pit has widened the pit dramatically, allowing a more rational design of ramps than was possible at the time the feasibility study was completed. This has actually resulted in a reduction in strip ratio of the Samaniego pit in spite of the depth of the new resources. Queenstake's president Chris Davie said: "We are delighted by the increase in reserves, increase in grade and decrease in strip ratio at Samaniego which will dramatically improve the overall economics of the Magistral project and are increasingly excited about the unexplored upside potential on the Magistral project. Significant exploration potential remains in possible extensions of the La Prieta zone as well as in additional identified, but as yet not drilled, exploration targets on this 10,000-hectare property. This is an exciting time for gold companies and their shareholders, and for Queenstake Resources in particular. Construction at Magistral is firmly in hand, there is cash in the treasury and the company is debt free. Queenstake is actively seeking new acquisition opportunities. "The gold price continues to strengthen and has surpassed $325 per ounce; by the fourth quarter of 2002 Queenstake will have joined the ranks of gold producing companies. Achieving production at Magistral is only the first step in a bigger strategy of building a mining company. The company's current market value is well underpinned by its existing resource, reserve and production capability."
