Sihayo Gold Limited announced this update on the latest results of exploration activities conducted on the PT Sorikmas Mining CoW located in North Sumatra, Indonesia. This includes the first results from scout drilling in progress on the Sihorbo South gold-silver target at Hutabargot Julu in the North CoW block, and the first results from reconnaissance rock sampling completed in the Tambang Tinggi mineral field located in the northeast corner of the South CoW block. The Company recently reported drilling results from the Penatapan prospect at Hutabargot Julu with historical results from Sihorbo South provided in Sihayo's September 2021 Quarterly Activities Report. The latest results from Sihorbo South are part of a targeted drilling program on this vein target, which follows on from the Phase 1 reconnaissance drilling program at Hutabargot Julu completed in April 2021. Sihorbo South, located about 1.5 ? 2 km south of Penatapan, was originally discovered by the Dutch and explored along a series of short drifts and shallow shafts probably in the early 1900s. It is one of several large vein targets identified by Company geologists during detailed prospecting and mapping along the southern part of the greater Hutabargot Julu prospect during 2006 to 2007. The epithermal vein system at Sihorbo South was delineated by surface mapping and 1,416 m in 13 scout diamond holes during 2012-13 (Figures 1 and 2). The NNE-SSW oriented vein-alteration system is up to 50 m wide and extends over at least 400 m strike-length. It is a moderately west-dipping zone containing banded-brecciated epithermal quartz veins up to 5 m or more wide with hanging wall vein splays and surrounding stockwork. The vein system is hosted in a package altered volcanic breccias and hornblende diorite intrusions. Local artisanal miners have been active at Sihorbo South over the past seven years, selectively mining parts of the top 50 m of oxidised vein outcrops from a series of shallow open cuts and narrow underground drives. Local mining is most active at the southern and northern ends of the vein system and appears to be sporadic along the strike of the vein system. Drilling is in progress at the northern end of this large vein target with a man-portable rig. A total of 1,337 m in twelve holes has been completed to date. Assay results have been received for the first three holes; HUTDD098, HUTDD099 and HUTDD101. Results for the other nine holes will be available over the next four to eight weeks and are expected to be announced by the end of the year. Highly encouraging gold-silver intercepts within strongly veined quartz-chlorite-illite-adularia-pyrite altered volcanic breccias were returned in the first three holes. A complete table of the drill hole collar details and intercepts is presented in Appendix 1b. A complete table of drill intercepts is presented in Appendix 2. Representative drill sections for holes HUTDD098, HUTDD099 and HUTDD101. Further results are expected in the coming months and will be announced accordingly. Hole HUTDD098 intersected the Sihorbo Vein structure at high angle (producing near true-width intercepts) between the previous holes HUTDD044, HUTDD045 and HUTDD056. Hole HUTDD099 intersected a well-developed quartz-chalcedony-adularia-carbonate breccia-vein structure intersected between 71.80 and 86.55 m down-hole and produced consistent gold grades varying from 0.5 ? 1 g/t Au and variable silver grades up to 75 g/t Ag. Hole HUTDD101 was drilled close to the portal of an historic Dutch adit. It intersected a solid vein from 25.10 m down-hole before being terminated in a local mine cavity from 27.50 to 27.90 m depth. Selective grab samples taken from local mine muck piles along the Sihorbo South vein target have also returned highly encouraging results. Four of six grab samples previously reported from local muck piles sampled at the southern end of the vein system returned gold-silver grades ranging from 9 to 61 g/t Au and 16 to 46 g/t Ag. Another 14 samples taken from the northern end of the vein have returned results in six of these samples ranging from 0.48 to 3.79 g/t Au and 102 to 3720 g/t Ag. These initial results have demonstrated that the mineralised vein extends below the existing workings and that significant grades and potential volume remain in the subsurface. its geologists are mapping and surveying the distribution and depth of these local mine workings to better understand their extent and estimate the amount of material removed in the subsurface. Information obtained to-date indicates that the historical mining was highly selective and large amounts of the top of the vein remain. The workings are believed to be generally shallow (less than 30-m deep) and are more focused on extracting softer, stronger oxidised vein material. The mineralised vein segment tested by these recent holes, HUTDD098, HUTDD099 and HUTDD101, and the historic holes HUTDD044, HUTDD045 and HUTDD056, represent about 100 m strike length. The vein structure has been tested down to about 100 m vertical depth. The Sihorbo South vein target is largely untested beneath and surrounding the active artisanal gold workings, and it appears open along strike potentially below cover rocks. In comparison with the Penatapan stockwork target located to the north, Sihorbo South appears to show stronger development of thicker mineralised veins within mineralised stockwork envelopes and demonstrates good potential for high grade ore shoots that appear to be silver-rich at the north end and gold-rich at the south end of the large vein structure. Drilling is planned to progress from north to south along the vein target over the coming months. The Company anticipates releasing new drilling results over the next few weeks. The first phase of follow-up drilling was completed on the Penatapan gold-silver stockwork target. A total of 2,577 m in 11 holes was completed for this program and results have been reported for the first seven eight holes.
