Sultan Minerals Receives Positive Metallurgical Results From Second Study

 Kena Property -- Gold Mountain Zone

Sultan Minerals Inc. (SUL-cdnx) is pleased to announce that it has received a second metallurgical report on its Kena Property, located north of Ymir in southeastern British Columbia

A core sample from the upper portion of drill hole 01GM-03 was independently taken for metallurgical testing by a major international gold mining company. The sample was crushed to minus _ inches and gold recoveries were investigated by preliminary agitated cyanidation leach testing (bottle roll) by McClelland Laboratories Inc. of Sparks, Nevada. As with the previous report, this study shows extremely encouraging results for gold recovery from the Gold Mountain Zone mineralization. The results of the study are tabulated below:

The results of this second metallurgical study are significant and confirm that the sample is amenable to cyanidation treatment at the _ inch feed size. McLelland Laboratories conclude that "a linear extrapolation of extraction between 24 and 96 hours (avg. 5.0%/24 hours) indicates that a gold recovery of over 70 percent could be achieved with 72 hours additional leaching". The results also confirm that good gold recoveries can be achieved with only minimal cyanide consumption.

In an initial metallurgical study, conducted by a different major international mining company, a more conventional approach was taken with the final bottle roll recoveries of 92 and 97 % obtained after crushing the host rock to minus 200 mesh (previously reported in News Release dated August 28, 2001). For comparison, the results of the previous study are summarized below:

- Two composite samples prepared from two separate 8 metre continuous intervals from diamond drill hole 01GM-02 were used in the preliminary metallurgical study.

- The composites contained 1.15-2.87 g Au/t and about 1.50 g Au/t. (Repeat assays varied widely due to the presence of coarse free gold.)

- The composites also contained 2.5-2.6% sulfide sulfur corresponding to approximately 5% pyrite.

- Bottle roll cyanidation and CIL test results showed that the gold in these two composites was not refractory and they were cyanide leachable to the extent of 92 to 97% in 24 hours.

- Gravity test results, involving passing a 100% minus 48 mesh particle size across a Gemeni table and hand panning the concentrates, gave gold recoveries of 36.1 to 43.2%

The very encouraging results of metallurgical testing conducted by these two senior gold mining companies will greatly assist the Company in its objective of developing a significant, viable gold deposit.

To date, 29 drill holes have been completed in the Gold Mountain Zone, with assay results pending for the last 11 holes. The current diamond drill program will be completed by year-end and an expanded drill program is proposed for early 2002. The Company is presently tracing the favourable Silver King intrusive -- Elise volcanic contact with an induced polarization survey in preparation for the 2002 drill program. Drill sites are located along a major logging access road which will be kept open through the winter.
