Burey Gold Limited (Burey) (ASX: BYR) is pleased to announce results for the first 10 RC drill holes for 490m on Lines 2 and 4 as shown in Figures 1, 2 and 3 at its Douze Match target area which lies immediately south of a dominant granite intrusion in the NW portion of PE 5049 on Burey's Giro Gold Project in the Moto Greenstone Belt, NE Democratic Republic of Congo ("DRC"). The shallow RC drilling programme was designed to test approximately 1km of the soil anomaly which extends over 4km x 2.5km at Douze Match.
Exceptional grades of 2m at 196g/t Au from 12m and 15m at 255.6g/t Au from 15m including 3m at 1,260g/t Au from 15m and 3m at 14.3g/t Au from 21m were reported from black quartz veins in ferruginous saprolite in DMRC003. A Belgian working was intersected with zero sample recovery between 14 and 15m. A second zone of 9m at 5.7g/t Au from 24m was reported from saprolite on the same line to the north. Significant grades of 20m at 7.1g/t Au from surface in DMRC005 and 12m at 21.2g/t Au from 3m in DMRC004 were also reported from laterite in holes drilled on Line 4. All holes drilled on Line 2 were from granites north of the contact shear with mafic volcanics and reported a best
intersection of 7m at 5.2g/t Au from 30m although this appears to be related supergene enrichment at the base of the weathered granites as shown in Figure 3. The shallow RC drilling programme was planned to cover a large portion of the significant gold in soil anomaly with results reported for 2 lines spaced 500m apart. Results are considered to be highly encouraging for a first pass of drilling.
All reported samples comprised 3m composite samples collected at the drill site. Individual sample metres comprising anomalous composite samples will now be selected for re-assay. Individual metre samples from the high grade mineralised zone in DMRC003 were also submitted for screen fire assay (results of which are currently pending) as a further check on the actual grades reported for this interval.
Chairman, Klaus Eckhof commented, "These are exceptional results from this initial shallow drilling programme at our newest target at Douze Match, the results from hole DM-RC003 are better than anything I have seen in my Moto-Kibali experience. Finding such high grade this early on the Douze Match anomaly suggests we have discovered a potential company-making prospect where we will now focus on testing along strike and to depth.
Further drilling will continue to define the extent of the mineralisation and also target greater depths down to 100m. While high grade occurrences are common in the region we have never seen intercepts of these exceptional grades"
Drilling confirmed that gold mineralisation is focused within quartz veins and silica altered volcanics with the sulphides (mostly pyrite) often exceeding 2-5%. Significant quartz veining and silica/carbonate alteration and pyrite were identified in mafic volcanics in almost all holes drilled south of current drilling on both lines. On Line 3 shown in Figure 1, the granite contact was identified southeast of DMRC027 at the NW end of Line 3. All holes drilled to the south of the contact showed strong quartz veining and pyrite mineralisation.
All mapping and interpretation to date has showed a strong ENE trend in sheared volcanics and alluvial workings which generally follow streams whose orientation is often controlled by underlying structures. This is clearly shown by the orientation of the Tango alluvial workings in Figure 1 where the Belgians and small scale miners produced gold from alluvial sediments over at least 1km to the NE of current drilling. In addition, interpretation of geophysics by Barrick-Anglogold who flew an airborne radiometric and magnetic survey over the project area in 1998 showed the Douze Match target area lies within the 30km shear zone which hosts the Giro mineralisation 20km to the south. This NW orientation is confirmed by offsets in the granite along a dominant NW trending zone of alluvial artisanal workings shown in Figure 1 and supports two mineralised trends within the Douze Match target area. Considering the current drilling is a first pass reconnaissance phase of shallow RC drilling and there is little exposure for detailed interpretation, it is possible that the high grade mineralisation intersected in holes DMRC003 and 5 occur within the same structure which trends to the NW. This will be confirmed in a planned hole to be drilled perpendicular towards the west between these two holes.
The current shallow RC drilling programme to define the source of high grade soil anomalies will be completed as planned. Samples from an additional 30 holes on Lines 2, 3 and 4 have been completed from the 3,000m drill programme planned to test approximately 1,000m of the high grade gold in soil anomaly. As follow up, all significant zones of mineralisation identified in the shallow RC drilling, which allows 6 metres of fresh rock at the end of hole to identify dominant lithologies before stopping the hole, will be followed up with conventional RC drilling down to depths exceeding 100m. This will confirm the true mineralised width and grade of mineralisation at Douze Match.
These results are particularly meaningful given they are only 30km from the world class Kibali Project, which hosts in the order of 17 million ounces of gold, and in 2015 produced 642,720 ounces of gold. Results further support potential for a significant new gold target on the Giro Project which will be better defined with additional drilling. A short programme of shallow RC holes will be drilled at Mangote to test the 1km gold in soil anomaly to the north of the recent Diamond drilling and Belgian mining.
Export of samples for an additional 30 holes to accredited SGS Laboratories in Mwanza where in- country fire assay facilities provide improved turnaround time for reporting of results is ongoing with next results expected in early July 2016.

The Douze Match target area lies immediately south of a dominant granite intrusion in the NW portion of PE 5049 on Burey's Giro Gold Project where artisanal mining is focused in granites along the sheared contact with NE trending banded iron formation (BIF) and volcano-sediments. Historically, the Belgians mined sheared and quartz veined volcano-sediments and alluvial sediments at their "Tango Prospect" within this contact zone although little information is known about the production at Tango as it is assumed all mined ore was processed at nearby Mangote.
