Sihayo Gold Limited announced the latest assay results received from exploration drilling recently completed on the Sihorbo vein target and the commencement of drilling on the Penatapan on the western side of Hutabargot Julu Prospect located in the northern block of the PT Sorikmas Mining Contract of Work, North Sumatra, Indonesia. A reconnaissance drilling program testing an extensive gold-soil anomaly in the northern half of the Hutabargot Julu prospect was completed in early 2021 and consisted of 4,806 m of diamond coring in 25 inclined holes. This program produced multiple gold-silver intercepts in 21 of the 25 holes, confirming the potential for both bulk-tonnage stockwork epithermal gold-silver mineralisation and locally higher-grade gold-silver vein targets in this large prospect area. The Company identified the Sihorbo vein located on the western side of Hutabargot Julu as a high priority target for follow-up drill testing from previous work. Limited drilling conducted on the Sihorbo vein target by the Company in 2013 produced two high-grade gold intercepts: 5.3 m at 17.1 g/t Au & 19 g/t Ag from 56.2 m in HUTDD046 and 1.15 m at 204 g/t Au & 55 g/t Ag from 83.4 m in HUTDD047, and a further mineralised intercept of 4.4 m at 1.0 g/t Au & 2.5 g/t Ag in HUTDD053. Local artisanal gold miners have partly exploited the Sihorbo vein at discontinuous intervals along a 400 m strike-length segment and down to about 50 m vertical depth. Initial grab samples of vein material from muck piles collected on these workings returned additional encouragement with high-grade gold and silver results of up to 175 g/t gold & 105 g/t silver. The Company has recently completed a follow-up exploration drilling program, which commenced in April 2021, testing the high-grade Sihorbo vein target. A total of 1,679 metres diamond coring in 8 inclined holes were completed using one man-portable drill rig. Only one hole intersected a mine cavity in the current program and this was redrilled at a steeper angle to avoid the cavity. It shows the approximate pierce-point position and selected mineralised intercepts along the vein structure. Assay results were previously reported for the first two holes, HUTDD082 and HUTDD083, with the following intercepts: 1.2 m @ 1.64 g/t Au & 29.6 g/t Ag from 32 m depth, and 0.6 m at 2.73 g/t Au & 50.1 g/t Ag from 144.7m depth in HUTDD082; 4.0 m at 2.12 g/t Au & 3.8 g/t Ag from 31 m depth and including 1.0 m @ 5.73 g/t Au & 6 g/t Ag from 32m, and 1.6 m at 1.49 g/t Au & 2.8 g/t Ag from 89 m depth in HUTDD083. Most of the holes from this program have returned gold-silver intercepts in multiple zones of <1-5 m wide zones of quartz-chalcedony-carbonate-sulphide veined, silica-clay-pyrite altered breccias and quartz diorite. The reported mineralised intercepts typically contain <5-10% veins ranging in width from <1 to 20 cm wide and showing textures that are dominantly massive to crudely banded. The veins intersected in this latest drilling program are characterised by predominantly mixed crystalline quartz and carbonates and there is locally abundant epidote on some of the vein fill and adjacent alteration selvages. Measured structural orientations show that individual vein orientations are highly variable but the gross trend is approximately north-south with moderate dips to the west.

Measured structural orientations show that individual vein orientations are highly variable but the gross trend is approximately north-south with moderate dips to the west. Results from the Sihorbo drilling program tend to downgrade this specific target area. However, these structures contain a low-volume of mineralised veining and the gold-silver grades are generally low and fail to support the continuity of higher grades along strike and at depth. The vein mineralogy, textures and associated patchy gold grades intercepted by recent drilling are indicative of deeper levels of exposure and probably represent the roots of a once-fertile vein structure that has been eroded over time. This is consistent with the current interpretation of Hutabargot Julu where block faulting associated with the Trans Sumatran Fault Zone has uplifted and down-dropped different segments of the mineralised rocks resulting in varying levels of erosion and preservation of the mineralised targets across this large prospect area. Current interpretation is that higher grade vein and stockwork targets have been uplifted and exposed toward the southern and western sides of the prospect, and that lower grade breccias and stockworks overlying potential high-grade fissure-feeder vein targets occur toward the northern and eastern sides of the prospect. Potential is seen at the nearby Penatapan epithermal gold target where local mining is more extensive and mineralised veins and stockworks may be less deeply eroded and better preserved within a possible down-dropped graben block. The Penatapan target was identified from active artisanal mining activities and from the results of reconnaissance drilling previously reported at Hutabargot Julu, including intercepts of: 9 m at 8.36 g/t Au & 9.3 g/t Ag from 8 m in HUTDD074; 8 m at 0.53 g/t Au & 3.5 g/t Ag from 34 m in HUTDD077; and 7.1 m at 1.6 g/t Au & 15.7 g/t Ag from 58.4 m in HUTDD080. Grab samples of banded and brecciated epithermal quartz-chalcedony-adularia-carbonate-sulphide vein material taken from muck piles at local mine workings across Penatapan returned gold grades of up to 76 g/t Au and 515 g/t Ag. This target has the potential to host bulk-tonnage stockwork gold-silver mineralisation and bonanza grade fissure veins. The Toka Tindung epithermal vein field in North Sulawesi may serve as an analogue for the gold-silver target at Penatapan. The Company has planned a 2,500 metre/10 hole drilling program as an initial test of the Penatapan vein system. The rig used on the Sihorbo program has been man-portered to the first proposed drill site at Penatapan and drilling has commenced. This initial drilling program is expected to take 2-3 months to complete. First results are expected in mid to late July. Concurrent with the drilling programs at Sihayo-2 and Sihorbo, a program of geotechnical and hydrogeological drilling is in progess to support the design work for the Sihayo Starter Project.
