LUPAKA GOLD COMPLETES FIRST RUN-OF-MINE BULK PROCESSING TEST

Lupaka Gold Corp. has completed its first run-of-mine bulk test of 342 tonnes achieving total recoveries of 83.6 per cent for gold and 95.5 per cent for copper, and has received the final report on the results. The processing test was run at a local Peruvian toll mill under the supervision of CERTIMIN SA, the company's metallurgical consultant.

Copper/gold, lead/silver and zinc concentrate streams were produced over six days of processing, with concentrate tonnes and average grades per tonne achieved as shown in the table.

Over the six days of continuous flotation, various modifications were made to improve the protocols. The table demonstrates the concentrate grades achieved during the best production run of 110 tonnes (equilibrium phase).

"As a first bulk test of run-of-mine material from our Invicta mine site, we are very pleased with these results. All three concentrates report attractive grades, and the test demonstrates that Invicta mineralization floats cleanly and is absent of any penalty elements. These are very saleable products. These results are a big step towards establishing Invicta mine's commercial viability," commented Gordon Ellis, president and chief executive officer of Lupaka Gold.

Recovery

Overall average percentage recoveries for each of the three concentrate streams produced are shown in the table.

Mr. Ellis continued: "We are pleased with these results and, in particular, with the quality of the concentrates. Bench tests previously carried out by the company's independent metallurgists indicate that overall recoveries could be improved by up to 10 per cent. We look forward to continuing the bulk test program towards attaining those levels of recovery."
