ASX/Media Announcement 21 March 2013 New Gold Anomalies Outlined at Yako, Burkina Faso Significant new gold-in-soil anomalies identified. Highly-anomalous results with auger samples returning grades up to 5.6 g/t gold. Anomalous results are believed to be related to bedrock hosted gold mineralisation. Several anomalies lie near the permit boundary and extend into TrueGold s 3.4Moz Karma Project area. Golden Rim Resources Ltd (Golden Rim, ASX: GMR) today announced it has received highly anomalous auger sample gold assays from a new prospect area, Mossoum Prospect, in the Yako Project, Burkina Faso, West Africa. The Mossoum Prospect is located in the NE corner of the Yako Project (Figure 1). A total of 1,039 auger samples were collected over a 200m x 50m grid. The location of the new samples, together with gold values are shown in Figure 2. A number of significant new NW-SE trending gold-in-soil anomalies with values up to 5.6 g/t gold have been outlined along the boundary with the adjoining 3.4Moz Karma Project owned by TrueGold (TSX: TGM). The Karma Project consists of several gold deposits. One of these, the 1.5Moz Kao gold deposit is located 3km NW of the Mossoum Prospect. Very little outcrop occurs in the region, however high resolution aeromagnetic data collected by Golden Rim suggests that a series of NW-trending faults link the gold-in-soil anomalies at the Mossoum Prospect to the Kao gold deposit area. A number of the auger samples at Mossoum comprise limonitic quartz vein fragments in weathered bedrock (Table 1). Golden Rim believes this is highly significant and suggests the auger holes have penetrated zones of primary gold mineralisation. Golden Rim plans to conduct infill auger sampling on 100m spaced lines to better define the gold-in-soil anomalies prior to reverse circulation drilling. -ENDS- Golden Rim Resources Ltd I ABN 39 006 710 774 I Level 2, 10 Outram Street, West Perth WA 6005, Australia I PO Box 378, West Perth WA 6872, Australia www.goldenrim.com.au I info@goldenrim.com.au I T + 61 8 9481 5758 I F + 61 8 9481 5759

TrueGold s (TSX: TGM) 3.4Moz Karma Project lies in the permits immediately adjoining the western and northern boundaries of Yako. Amara Mining PLC s (Amara; LSE: AMA) 0.6Moz Sega gold deposit lies in the permit immediately adjoining the eastern boundary of Yako. About 16km SE of Yako, Amara operates the 0.8Moz Kalsaka Gold Mine. Amara recently purchased the Sega gold deposit for US$28.9 million and plan to truck the gold resource to Kalsaka. Six major artisanal mining sites are located within the Yako Project. Drilling on these sites conducted by Golden Rim has returned significant oxide gold intercepts including 15m at 5.0 g/t gold, 12m at 5.7 g/t gold and 19m at 4.1 g/t gold. Page 2
