ASX/Media Announcement 10 July 2012 More High Grade Gold Intercepts from the Netiana Lodes at Balogo, Burkina Faso New reverse circulation (RC) hole intersections include: o 12m at 20.5 g/t gold from 73m, including 3m at 77.8 g/t gold from 74m (BRC219). o 8m at 4.4 g/t gold from 100m (BRC219); o 16m at 4.8 g/t gold from 95m (BRC220); o 7m at 22.8 g/t gold from 120m, including 2m at 72.3 g/t gold from 123m (BRC220); o 7m at 17.3 g/t gold from 77m, including 2m at 54.4 g/t gold from 77m (BRC221); o 6m at 20.5 g/t gold from 54m, including 2m at 59.3 g/t gold from 55m (BRC224). New diamond hole intersections include: o 20.8m at 4.7 g/t gold from 50.2m, including 3.3m at 20.2 g/t gold from 59.8m (BDH001R); o 3.9m at 37.9 g/t gold from 161.1m (BDH002); o 5.3m at 11.8 g/t gold from 193.6m (BDH002); o 11m at 9.8 g/t gold from 96m, including 2m at 29.6 g/t gold from 103m (BDH006R). Most holes intersected multiple high grade gold lodes which display good continuity through the central portion of Netiana. These gold lodes remain open at depth. Golden Rim Resources Ltd (Golden Rim, ASX: GMR) today announced further assay results from RC drilling and the first assay results from the maiden diamond drilling program on the Netiana Lodes at its Balogo Project in Burkina Faso. Golden Rim s Managing Director, Mr Craig Mackay, said The recent infill RC and diamond drilling has been highly successful and has confirmed the continuity of the multiple high grade gold zones which comprise the central portion of the Netiana Lodes. The drilling to date has tested the Netiana Lodes to an average depth of only 85m and the Company will now conduct a deeper diamond drilling program at Netiana with the aim of outlining significant depth extensions to the high grade mineralisation, Mr Mackay said. A total of 1,941 new assays were received for 14 infill RC holes drilled at Netiana. All results have been received from the central part of the Netiana Lodes (Figure 1). Five holes (527m) remain pending, however these holes are located around 300m to the NE and SW of the main mineralised zone at Netiana.

Assays for selected zones of diamond holes BDH001R, BDH002, BDH006R and BDH007R were received. Only parts of each hole where obvious mineralisation was observed were sampled. Systematic sampling of the remaining parts of each hole is now complete but assays are pending. A list of all new significant gold intercepts is provided in Tables 1 and 2. The infill RC and the diamond drilling have confirmed the continuity of multiple high grade gold zones which comprise the central portion of the Netiana Lodes. The drilling to date has only tested these high grade gold lodes to an average depth of approximately 85m and there is considerable scope to extend this mineralisation at depth. The more significant new gold intercepts were obtained on 4 drill sections (10,000N, 10,025N, 10,050N and 10,075N) and are discussed below. Drill Section 10,000N Results for parts of diamond holes BDH001R and BDH002 drilled on section 10,000N were received (Figure 2). BDH001R was collared approximately 10m beneath the discovery hole BRC071. BDH001R intersected 20.8m at 4.7 g/t gold from 50.2m including 3.3m at 20.2 g/t gold from 59.8m with gold mineralisation associated with a series of steeply dipping quartz / sulphide veins that are hosted in diorite. The location of the intercept in BDH001R correlates well with the high grade zone in BRC071 although the grade of the diamond hole is lower. This was expected, as being deeper, the intercept in hole BDH001R has a lesser oxidised component than the intercept in BRC071, and it is believed there is some supergene gold enrichment at the base of the oxidation zone at Netiana. BDH002 is the deepest hole drilled on the Netiana Lodes to date and it successfully intersected two high grade mineralised lodes, at approximately 140m below surface, which correlate well to intercepts from the shallower RC holes. BDH002 intersected 3.9m at 37.9 g/t gold from 161.1m and 5.3m at 11.8 g/t gold from 193.6m, including 1m at 56 g/t gold. Both these intercepts are higher grade than indicated by RC intercepts at higher levels suggesting gold grades may be increasing with depth. Drill Section 10,025N Results were received for 5 holes (BRC214, 215, 216, 219 and BRC220) completed on Section 10,025N. Previous high grade intercepts on this section include 15m at 17.7 g/t gold from 18m, including 1m at 163.9 g/t gold and 4m at 8.4 g/t gold from 72m in BRC 217 and 31m @ 27.8 g/t gold from 48m, including 5m @ 122.5 g/t gold and 12m @ 3.9 g/t gold from 84m in BRC 218 (Figure 3). BRC219 and 220 were both drilled below BRC218. Both holes intersected the same two zones of mineralisation hit in previous holes and effectively increase the down-dip extent of the mineralised system by around 50m. The first zone intersected in BRC 219 was 12m at 20.5 g/t gold from 73m, including 3m at 77.8 g/t gold from 74m. The second intercept was 8m at 4.4 g/t gold from 100m. Page 2
BRC 220 intersected 16m at 4.8 g/t gold from 95m (including 1m at 24.7 g/t gold from 101m and 1m at 30.1 g/t gold from 103m). As there was no sample return for the interval 102 to 103m, the true grade of the intercept may be underestimated. No holes have been drilled beneath BRC220, and the gold mineralisation remains open at depth. Holes BRC 214, 215 and 216 were drilled up-dip of BRC 217. BRC 216 intersected 2m at 12.4 g/t gold from 7m (including 1m at 24.2 g/t gold) which correlates to the up-dip extension of the shallower intercept in BRC 217. It is likely that the full zone was not tested due to mineralisation terminating at the saprolite interface. A second zone in BRC216 of 9m at 1.9 g/t gold from 48m correlates well with the deeper intercept in BRC217. Lower grade intercepts in BRC 215 (2m at 4.2 g/t gold from 37m) and BRC 214 (2m at 2.5 g/t gold from 15m) also appear to correlate with the second zone of mineralisation. Drill Section 10,050N One hole (BRC221) was drilled below BRC042 which previously intersected 14m at 2.5 g/t gold from 38m and 5m at 32.5 g/t gold from 70m (Figure 4). BRC221 intersected both of these zones (7m at 17.3 g/t gold from 77m, including 2m at 54.4 g/t gold from 77m and 7m at 1.2 g/t gold from 88m) confirming the down-dip continuity of the mineralisation at 30m below BRC221. Diamond hole BDH006R was completed approximately 25m below BRC221 and intercepted 11m at 9.8 g/t gold from 96m, including 2m at 29.6 g/t gold, at approximately 80m below surface. The mineralisation remains open beneath this depth. Drill Section 10,075N Results were received from two holes (BRC 222 and BRC 224) on this drill section (Figure 5). BRC 224 intersected 6m at 20.5 g/t gold from 54m, including 2m at 59.3 g/t gold from 55m and confirms the down-dip extent of mineralisation previously intersected in BRC 245 (11m at 7.8 g/t gold from 33m) by approximately 15m. The significant gold mineralisation on Section 10,075N remains open at depth and drilling to date has tested the mineralisation to only 45m below surface. Deeper drilling is required. Future Work Program Currently, Golden Rim is upgrading the camp facilities at Balogo in preparation for a major diamond drilling program which is scheduled to commence in September following the end of the rainy season. The diamond drilling will be focussed on testing the central portion of the Netiana Lodes below 85m depth with the aim of outlining significant depth extensions of the high grade mineralisation. Golden Rim also plans to utilise existing and new diamond core to conduct preliminary metallurgical test work. -ENDS- Page 3
