Southern Arc Minerals Inc. (TSX Venture: SA) is pleased to announce that drill hole SLD013, drilling at the northwest extremity of the Montong Botek high‑grade Cu-Au porphyry target on its Selodong Intrusive Complex (SIC) prospect on Lombok, Indonesia, has returned the longest mineralized intercept to date, intersecting a broad mineralized interval along nearly the complete length of the hole of:

  576.95 m at 0.12% Cu and 0.25 g/t Au from 0.00 m to 576.95 m
  113.9 m at 0.06% Cu and 0.34 g/t Au from 21.50 m to 135.40 m
106.6 m at 0.18% Cu and 0.30 g/t Au from 262.75 m to 369.35 m
52.0 m at 0.15% Cu and 0.45 g/t Au from 441.35 m to 493.35 m


SLD013 was collared 150 metres northwest of the historic Newmont drill hole SGD001 to test potential northwestern extensions of high-grade Cu-Au mineralization (QD1) intersected in drill holes SLD001, SLD002, SLD003 and SGD001. Given that Southern Arc's more recent drilling work in this area has been to test extensions of the known high‑grade mineralization at Motong Botek and Blongas II, the results from SLD013 are very encouraging and have further extended Cu-Au mineralization to the northwest extremity of the target

SLD013 adds to the known mineralization identified by Southern Arc with holes SLD001, SLD002, SLD003 and SGD001.

SLD001 returned 442.2 m at 0.28% Cu and 0.42 g/t Au from 33.8 m to 476.0 m.

SLD002 returned 384.65 m at 0.30% Cu and 0.40 g/t Au from 18.1 m to 402.75 m.

SLD003 returned 363.50 m at 0.30% Cu and 0.51 g/t Au from 33.30 m to 396.80 m.

SGD001 returned 416.0 m at 0.21% Cu, 0.31 g/t Au from 2.0 m

SLD013 was drilled north-northeast at an inclination of -65 degrees to a depth of 600.0 m. Dacite and quartz diorite intrusives were logged from surface to 28.0 m. From 28.0 m to the end of the hole polymictic breccia, with variable amounts of mineralized quartz diorite (QD1) clasts, was intersected. Similar QD1-style stockwork veining has been mapped elsewhere in the vicinity of the SLD013 collar. Abundant altered and mineralized diorite clasts within the polymictic breccias are very encouraging and may indicate the potential of proximal QD1 hosted mineralization east and north of SLD013 as well as at depth.

SLD015 was located 160 m west of SLD013 to further test inferred NW extensions of Montong Botek Cu-Au mineralization. Detailed geologic mapping had shown continuity of anomalous quartz stock work outcrops into this area. Two zones of lower-grade Cu and Au mineralization were intersected including;

53.0 m at 0.07% Cu and 0.23 g/t Au from 260.0 to 313.0 m
232.0 m at 0.05% Cu and 0.17 g/t Au from 361.0 to 593.0 m
SLD015 was drilled at the same orientation and inclination as that of SLD013 to a depth of 600.4 m. Late stage post-mineralization diorite was drilled from the surface to 129.0 m. From 129.0 m to the end of the hole mineralization is associated with variably phyllic altered QD1 clasts hosted in polymictic breccia. The locations of drill holes SLD013 and SLD0015 at Montong Botek are shown in Figure 1.

SLD012 and SLD014 located at the Belikat porphyry prospect targeted extensions of anomalous Cu‑Au intersections from previous shallow Newmont drill holes (Figure 2). These holes targeted anomalous geophysical and geochemical signatures coincident with extensive zones of outcropping quartz stockworks. Phyllic and propylitic altered diorites and minor breccias were intersected in both drill holes hosting zones of quartz stockwork and low-grade Cu-Au mineralization (see Table 1).

These results indicate the presence of an extensive area of porphyry style alteration and mineralisation which remains largely untested at Belikat. Hole SLD012 intersected a number of lower-grade zones of Cu‑Au mineralization. Hole SLD014 returned 77.45 m grading 0.13% Cu and 0.22 g/t Au. Further work at Belikat will be considered while drilling continues on other Selodong targets.

SLD012 was drilled west at an inclination of -65 degrees to a depth of 600.0 m whilst SLD014, located 330.0 m southwest, was drilled south-southwest at an inclination of -65 degrees to a depth of 600.0 m .


Southern Arc's on-going drilling program on the SIC will continue to meet its strategic objective, that is, to test both lateral and depth extensions of Cu‑Au mineralization at Montong Botek, Blongas II and Blongas I along with drill testing of the other 12 peripheral porphyry targets such as Kedaro and Lapangan Geres.

Three drilling rigs are concurrently in operation on the SIC. Rig No. 1 and the larger deep drill (Rig No. 3) are focused on testing the lateral and depth extensions of Montong Botek, Blongas II and Blongas I to better define the size of mineralization of the target, while Rig No. 2 continues to drill test the other 12 porphyry Cu-Au targets that comprise the 15 SIC targets.

  • Drill Rig No. 1, with a capacity to reach a depth of 600 m, is focused on testing the lateral extensions of Motong Botek, Blongas II and a Blongas I to medium depth. These three porphyry targets form a N to NW-trending structural corridor hosting porphyry copper-gold mineralization approximately 280 m wide and 1,700 m in length. This area coincides well with mapped surface exposures of porphyry-style stockworking, Cu-Au-Mo soil geochemistry and linear magnetic highs associated with secondary magnetite alteration. A number of future drill holes will test the depth extent and grade of mineralization along the strike length of this area. Drill Rig No. 1 has completed hole SLD018 to test for a southern extension of Montong Botek, for which assay results are being awaited, and it is currently drilling hole SLD020 halfway between Blongas II and Montong Botek.
  • Drill Rig No. 2, also capable of reaching a depth of about 600 m, will continue to drill test the remaining 12 SIC Cu-Au porphyry targets. Drill Rig No. 2 has completed hole SLD016, testing the northern extent of the Kekalik anomaly, and the assay results are being awaited. It is currently drilling hole SLD019 at the Kedaro target.
  • Drill Rig No. 3, capable of drilling to 1,100 metres, is focused on establishing continuity of grade at greater depth at Montong Botek, Blongas II and Blongas I, and any new high-grade targets that become identified. In the near term, the rig will progressively be moved northward from Montong Botek towards Blongas II. It is currently drilling hole SLD017 from the western flank of Montong Botek into the centre of that porphyry target.
