"In almost all of our target areas, we have either identified significant new mineralization or confirmed the continuation of previously-identified zones. We are particularly pleased with the excellent results at Kumtor and as a result have increased the budget for the second half of 2005 by $2 million in order to keep drilling throughout the year. The Gatsuurt deposit continues to exceed our expectations with results from the Main Zone which have the potential to further improve the economics of the project." "These first-half results have confirmed that we are on track to significantly increase the Company's reserves and resources and deliver on our objectives. They build on the momentum established in 2004 that resulted in meaningful extensions of the mine lives at Kumtor and Boroo. This was followed by further exploration success at the Gatsuurt deposit which justified the initiation initiation, the transition and attendant ceremonies, such as ordeals and rites, involved in passing from one state or status to another, often from childhood to adulthood.

Kyrgyz Republic Drilling in the vicinity of the Kumtor pit focused on testing for down dip extensions beyond the ultimate pit design at the southern and northern ends of the deposit, shallow drilling in the northern highwall area and drilling along strike of the deposit to the northeast. The 2005 program in the first half consisted of 74 diamond drill holes totaling 22,641 metres. The highlights from the program are as follows: At the southern half of the pit, drilling tested for down dip extensions to the mineralization beyond the limits of the ultimate pit design. The mineralization encountered in the southernmost 200 metres of the drilled strike length (SB Zone) is significantly thicker and higher grade than predicted by the KS5 block model with down hole intercepts varying from 26 metres to 68 metres and average grades in the 4 grams per tonne tonne measure of weight or mass; 1 tonne=1000 kg. See also ton. ("g/t") Au to 13 g/t Au range. The tops of the shallower intercepts are typically within 75 metres of the ultimate pit design. This zone remains open at depth and to the south. Other drill holes to the north of the SB Zone intersected the target horizons in areas that were only tested by widely spaced holes. Most of these holes returned intercepts that confirmed the existing KS5 resource block model. Geotechnical and engineering studies have been initiated to assess the potential for an open pit expansion and/or to justify an underground scoping study. In the northern portion of the pit, drilling in 2005 further delineated a thick mineralized zone (NB Zone) intersected during last year's program. The zone starts at a depth of about 100 metres beyond the ultimate pit design and has now been delineated over a 200 metre metre In poetry, the rhythmic pattern of a poetic line. Various principles have been devised to organize poetic lines into rhythmic units. Quantitative verse, the metre of Classical Greek and Latin poetry, measures the length of time required to pronounce syllables, strike length and an additional 120 metres down dip. Down hole intercepts in the new holes at the target horizon vary from 26 metres to 64 metres thick with average grades typically in the 3 g/t Au to 5 g/t Au range. The zone remains open down dip and possibly down plunge The term Plunge has multiple meanings:
Along the northern flanks of the deposit in an area with minimal prior drilling, two of the 15 drill holes, D972A and D977A, encountered significant mineralized intervals at the northernmost part of the drill pattern.

Mongolia Drilling at the Boroo mine focused on delineation drilling in the vicinity of Pit 6, testing for additional mineralization along the western and northern flanks of Pit 3 and early stage testing of the Boroo 4 exploration target. The 2005 program in the first half consisted of 143 reverse circulation (RC) holes and two diamond drill holes for a combined total of 145 holes totaling 18,614 metres. The highlights from the program are as follows: In the relatively untested north end of Pit 6, 64 holes were drilled. The new drill holes delineated a corridor of mineralization over an area 350 metres long by 30 metres to 60 metres wide with grades typically between 1.5 g/t Au to 3 g/t Au over 5 metres to 20 metres down hole intervals. The down hole depths to the top of the intercepts vary from 70 metres to 125 metres. The southern 100 metres along this corridor is typically higher grade with several holes containing intercepts averaging up to 8 g/t Au. An additional 27 holes drilled around the flanks of the Pit 6 area confirmed the existing resource block model interpretation. Along the western and northern flanks of Pit 3, 52 holes were drilled beyond the ultimate pit design in areas previously tested by wide spaced holes. The new holes mainly tested for additional mineralization in the down dip direction. In general, the results confirmed the existing resource block model interpretation. In the central portion of Pit 3, the mineralization continues to depth with grades typically in the 1.3 g/t Au to 2.5 g/t Au range over 10 metres to 30 metres down hole intervals. The mineralization appears to be closed off in the down dip direction along the flanks to the northwest and southwest. Five holes drilled in the vicinity of the Boroo 4 prospect, located about two kilometres to the north of the Boroo mill, did not encounter any significant mineralized zones.

Drilling at the Gatsuurt Central Zone deposit focused on selective in-fill drilling, defining the limits to the mineralization and testing for further strike extensions to the mineralized zone. Excluding drill holes used in the resource estimate disclosed on April 29, 2005, the first half of 2005 program consisted of 24 RC holes and nine diamond drill holes for a total of 33 holes totaling 4,929 metres. The highlights from the program are as follows: Sixteen holes were drilled to in-fill within the existing drill pattern or to test the mineralization at greater depths. These results have essentially confirmed the geometry and the grade of the block model interpretation used in the latest resource estimate which resulted in an indicated resource consisting of 11.3 million tonnes at an average grade of 3.52 g/t Au for a total of 1.3 million contained ounces of gold. Continuous mineralization extends over a strike length of 900 metres and the mineralization remains open at depth over a significant portion of the deposit. Seventeen holes drilled in the southern and northern flanks of the Central Zone to test for strike extensions to the deposit did not encounter significant new mineralization.

The Gatsuurt Main Zone is located 400 metres to the southwest of the Central Zone. Gold mineralization occurs in a wide, subvertical structural zone cutting a Permian rhyolitic volcanic sequence. This area was previously tested by nine holes spaced over an 800 metre strike length and 10 shallow holes along two drilling fences. The objective of the 2005 drilling program is to further assess the grade distribution and size potential of this mineralized zone. Three RC holes and 11 diamond drill holes have been completed for a total of 14 holes totaling 2,711 metres. Most of the Main Zone drilling was completed over a 650 metre strike length of the mineralized zone with drill holes generally spaced at 70 metres along strike and 70 metre offsets down dip.

Drilling results are encouraging and have confirmed the continuity of broad zones of mineralization over a 400 metre strike length. The mineralized system appears to weaken along strike to the northeast and southwest, but remains open at depth. Preliminary flotation flotation or froth flotation Most widely used process for extracting many minerals from their ores. The method separates and concentrates ores by altering their surfaces so that they are either repelled or attracted by water. test work indicates that gold recoveries to concentrates are similar for the Main and Central Zones, with 87% and 90% of the gold reporting to the combined gravity and flotation concentrates for two composites from the Main Zone.

The drill results have determined the limits to a better mineralized corridor measuring about 600 metres by 150 metres with typical gold values of 1.5 g/t Au to 2.5 g/t Au over 4 metre to 10 metre down hole intervals. The best intercept returned 8.79 g/t Au over a 2.5 metre interval starting at a depth of 76.5 metres. The Argal target area is located about 100 kilometres to the southwest of the Boroo mine.

Limited previous drilling identified an auriferous horizon with grades typically in the 0.8 g/t Au to 3.5 g/t Au over 2 metre to 16 metre intervals. During 2005, this target was further assessed by 16 RC holes and two diamond drill holes for a total of 18 holes totaling 2,464 metres. The drilling program did not encounter more substantial mineralized zones and this target has been downgraded. The Biluut target area is located three kilometres north of the Gatsuurt Central Zone.

One hole intersected a sulfidic alteration zone which returned 2.64 g/t Au over 10 metres starting at a down hole depth of 44 metres. Follow up drilling is planned. The remaining three holes did not encounter any significant gold mineralization. A 43-101 compliant Technical Report on the Boroo mine was filed on May 14, 2004 and a Technical Report on the Gatsuurt deposit was filed on February February: see month. 25, 2005. Both reports are available on the System for Electronic Document Analysis and Retrieval ("SEDAR") at www.sedar.com. The reports describe the exploration history, geology and style of gold mineralization at each of the Boroo and Gatsuurt deposits, respectively. Sample preparation, analytical techniques, laboratories used and quality assurance-quality control protocols used during the drilling programs at the Boroo mine, in the Gatsuurt area, and at the Ulaan Bulag, Argal and Biluut prospects are the same as, or similar to, those described in the Technical Report for the Gatsuurt deposit.

Corporation (38%). During 2004, a new mineralized zone called the 69 Zone was discovered and by year end, it had been intersected by five holes. These drilling results were incorporated in the latest resource estimate for the REN project released on January January: see month. 27, 2005. During the first half of 2005, drilling focused on testing for additional mineralization around the 69 Zone, testing geological targets in the southern portion of the property and offsetting a high grade intercept in the JB Zone. Due to the significant depths to the target horizons, the drilling program typically consists of diamond drilling Diamond Drilling is a highly specialized industry used for mineral exploration around the world. Most commonly using wireline and core bits with diamond encrusted matrix. To drill holes to max depths of twelve thousand feet, for the recovery of core used in verifying mineral core 'tails' from RC pre-collars, and the use of wedges and directional drilling Directional drilling (sometimes known as slant drilling outside the oil industry) is the science of drilling non-vertical wells. Directional drilling can be broken down into three main groups: Oilfield Directional Drilling, Utility Installation Directional Drilling (commonly to provide multiple core tails from a single pilot hole. The first half of 2005 drilling program consisted of nine completed holes and two RC pre-collars for a combined total of 6,813 metres. The highlights from the program are as follows: Five holes were drilled to offset mineralized holes in the 69 Zone.

Three RC holes were drilled to test geological targets in the southern portion of the property where the depths to the prospective rock assemblages in the lower plate of the Roberts Mountain thrust fault vary from 400 metres to 700 metres. Encouraging results were encountered in drill hole RU-83 which intersected a wide zone of low grade mineralization at the target horizon. This intercept will be followed up by additional drilling. The remaining holes did not encounter any significant mineralized zones. Most of the gold resources on the REN property are located in the JB Zone discovered in 2002. One in-fill hole was drilled in 2005 to assess the grade continuity in a high grade portion of the resource area near the eastern boundary of the JB Zone. This hole returned 49.07 g/t Au over 15.2 metres. The hole pierced pierced adj. 1. Cut through with a sharp instrument; perforated. 2.

The new intercept is significant in that it indicates that there is good continuity to the high grade mineralization in this area.
