Southern Gobi Belt

Exploration Strategy

The Kincora technical team is credited with multiple discoveries of Tier 1 copper deposits and is undertaking the first modern district-scale exploration program in the world-class Southern Gobi belt. The Company is now executing a proven exploration strategy and systematically advancing a wholly owned pipeline of targets up the value curve.

Southern Gobi Belt Exploration Strategy 1


West Kasulu bulk tonnage sulphide prospect

A key work program in 2017 was the Mining Associates review of the West Kasulu prospect, which was the first major advancement at Bronze Fox since resolution of the previous dispute that between 2013-2015 restricted access to the full Bronze Fox Intrusive Complex (BFIC) and, within it, the West Kasulu prospect.

The review and block model announced in the January 25th, 2018 press release supported a larger tonnage exploration target than internally expected at 416 Mt to 428 Mt grading 0.26% to 0.30% copper for up to 2,437Mlb of copper and 0.84Moz gold, ranking as one of the largest potential in-situ copper-gold systems in Mongolia and with only modest drilling. The potential quantity and grade ranges are conceptual in nature and based on nearest neighbour and ordinary krige estimates, and there has been insufficient exploration to define a mineral resource. It is uncertain if further exploration will result in the target being delineated as a mineral resource.

Kincora has undertaken only one drilling season (2012) across the full BFIC and West Kasulu prospect, noting this was prior to the “Search” Induced Polarization (IP) program (2013), which achieved better resolution and deeper penetration than prior survey’s. Results from this 2012 drill season were some of the most prospective in the wider Southern Gobi belt, attracting 14 NDAs with industry groups and a period of exclusivity. Full 2012 results and interpretation were impact by the aforementioned dispute, with only 24,139 metres in total (for 76 holes) having been drilled in total across the 1.3km strike at West Kasulu (by Ivanhoe Mines, Temujin and Kincora).

The Mining Associates review identified the “Tov” fault that bisects the West Kasulu prospect and that a North-West monzonite zone had more encouraging grades in holes F57, F85 and F62 (the latter including 37 meters at over 1% copper equivalent), indicating a more potentially favourable preservation level in the porphyry setting. This NW zone has had limited exploration, with only 4 holes for 2,170 metres by Kincora in 2012 and 24 holes for 3,841 metres by previous tenement holders. Drilling efforts by previous holders focused on soil and rock chip anomalies, often with zones of high-grade mineralization down hole, noting a largely untested IP chargeability anomaly at relatively shallow depths.

The 2017 field season review Workshop revisited the West Kasulu prospect for a proposed “advanced” drilling program in 2018, focused on predominately targeting higher-grade potential in the NW monzonite zone. Post the Mining Associates review, Kincora has been analysing the previously relogged 11,991 metres of core (from 24,139 metres drilled at West Kasulu) and other work programs undertaken during the period of exclusivity in 2014 with a copper major (during the period of dispute for the western license and during the early stages of the copper price correction), and following up a number of the recommendations made by Mining Associates.

The Mining Associates review and subsequent activities have assisted provide an improved geological understanding of the West Kasulu target and its bulk tonnage copper porphyry system. Encouragement is provided by the spacing between previous limited drilling in this NW zone, including up and down dip potential from previous higher grade intersections, previous drilling on the western license having been generally limited to approximately 100m depth grid drilling and supportive geophysics remaining largely untested (particularly in the western license).

Further relogging of existing drill core is a priority in the upcoming Spring to assist refine targets for potential drilling at West Kasulu and providing further geological data that would be required to upgrade the Mining Associates exploration target to a NI 43-101 compliant resource. Initial steps have also been taken to support potentially converting the existing exploration license to a mining license.

West Kasulu oxide prospect

Between 2012/13 various internal and external analysis and studies were undertaken exploring the potential for a small-scale, near cash flow, oxide SXEW development project. These efforts were lead by John Rickus, Kincora’s late chairman who had considerable experience in copper development projects, with input from various specialist consultants.

Initial mineralogy and metallurgical studies (including bottle roll tests by Wardell Armstrong), a block model (by Micromine), 10 infill drill holes, with investigations for sourcing acid, water and access to power where undertaken. A high level internal financial model illustrated favorable economics of such a development project assuming long term copper at $3.20/lb subject to successful infill drilling, further analysis on copper recoveries/acid consumption (due to some clays being identified in initial metallurgical and mineralogy analysis) and the systematic advancement of studies (noting this was prior to grid power being available in the immediate region, which would likely lead to a saving in capex and opex to original estimates, and the construction of a water well at Bronze Fox).

Kincora is revisiting the potential of the oxide project in light of the relogging of core at West Kasulu (that will assist refine the oxide and transitional profile), looking to convert the Mining Associates exploration target to NI 43-101 standards, the improved copper price and further drilling at Bronze Fox expected in 2018.

Field season activities in 2017 confirmed Kincora’s interpretation that the East TS porphyry target sits in a brownfield environment on the interpreted eastern margin of the Devonian age Tsagaan Suvarga (“TS”) intrusion, which hosts Mongolyn Alt LLC’s (MAK) Serven Sukhait open pit development project and southern exploration targets on the western margin. MAK has invested US$377 million of a reported US$1,089 million total capital cost into the development of TS, which is forecast to annually produce up to 316,000t of copper and 4,400t of molybdenum concentrate.

Mapping, infill soil sampling and drilling has confirmed the targeted fertile and Devonian age quartz monzonite and monzonite intrusion at East TS. Half of the 14 holes from the maiden drilling program, for 3,452 metres, intersected the TS intrusion (two of which were underlying carboniferous cover).

Age dating, green rock, petrographic, lithogeochemical and geochronological analysis have been positive, with infill ground magnetics and maiden ground gravity survey’s completed post the first phase drilling program. A review of the 2017 geophysics has identified three interpreted intrusive bodies with four targets for follow up, which may represent multiple intrusive centers with favourable geological and geophysical, and the correct structural setting for a fertile porphyry system.

The background copper with molybdenum returned in a number of the first phase holes and detailed magnetic susceptibility readings has provided encouragement for the interpreted porphyry clusters and indicated a number of holes from Phase 1 might have stopped short of geophysical anomalies identified (eg in particular holes 3 and 5) or on the margin (eg hole 12 and 14).

Activities to date support the East TS target being in the right geological and structural setting to the Serven Sukhait open pit (307Mt @ 0.54% Cu resource) and southern exploration targets on the western margin of the TSIC. Further encouragement is provided from both surface mapping and drilling that has intersected interpreted lower carboniferous cover above the Devonian TSIC, which coupled with improved interpretations of key structural and fault features, supports the concept of a potential preserved Devonian complex. The later is an analogue for East TS hosting an equivalent preserved high grade Hugo or Heruga orebody as at Oyu Tolgoi.

With improved geological and geophysical knowledge an Induced Polarization (IP) survey is planned for the Spring to assist target sulphides within a 40km2 area of interest, and is expected to lead to a second phase target testing drilling program in the summer or autumn.

The Tourmaline Hills target sits within a large carboniferous age intrusive complex that outcrops on the western of the two-licenses that form the Bronze Fox project. Previous rock chip samples and soils have identified high grade gold, which has been the focus of ninja activities in 2014 and again over the 2017/18 winter. These ninja activities have been in different zones, with 2014 activities focused on small pits (no underground), and 2017/18 activities going underground.

Drilling by Ivanhoe in 2006 and by Kincora in 2012 (limited to one drill season each – for Kincora impacted by the 106 license dispute, resolved in 2015) intersected zones of structurally controlled higher grade gold, often with copper.

Post Kincora’s January 2018 workshop, a soils and mapping program over the ninja zones and outcrop utilising our XRF is proposed, with stream sediment pan sampling program designed for course gold and magnetic readings are propose to better understand the outcrop and ground magnetic survey results.

A field trip in mid March was undertaken to review of ninja mining activity that has taken place over the winter, to assist both understand potential reclamation activities but also seek to better understand the geology of the areas informally mined and what the ninjas were targeting (given they were a key element to the discovery of Erdene’s Bayan Khundii and Xanadu’s Oyut Ulaan).

A number of samples were taken across the areas mined, with one grab sample returning 282g/t Au from a pit/trench where informal mining activities occurred in 2014. The sample was from an ankerite vein with brecciation and limonite staining, with no visible gold.

Further samples have subsequently been taken to assist understand the gold tenure in the identified vein, see if such grade results can be repeated, and wider zone historically mined, and advance geological understanding of a potential target and strike (orientation relative to previous exploration and distance) that might warrant higher prioritization. Follow up activities and any disclosures to market will be results dependent.

The Red Well license is approximately 40km north of the Oyu Tolgoi concentrate plant, along the general NNE arc transverse trend from Oyu Tolgoi, and immediately to the north of Rio Tinto drilling activities in 2017 on a Turquoise Hill Resources license, the later being the first regional drilling by either major group since 2012.

Ground magnetics and gravity completed in 2017 supports shallow cover within the northern section of the license with a historic reported Induced Polarization high anomaly coincident with outcrop. Initial ground truthing has failed to identify or replicate historic copper grade samples on the margin of the license with calcic-sodic alteration identified along eastern margin of the outcropping intrusion with positive fertility indicators returned from analysis undertaken by Kincora.

Kincora’s geophysics indicates deep cover to the southern section of the license, supporting an uplifted (horst) block in the central-northern portion of the Red Well license, relative to the deep drilling program completed by Rio Tinto in 2017 on the adjacent southern license. A soil and mapping program over the outcropping region, with a wider stream sediment sampling is planned at Red Well for the Spring.

Infrastructure to and around the license is very favourable, with a phone tower on the license and located 35km northwest from the Khanbogd soum (the local province center).

Previous IBEX drilling based on Zeus Induced Polarization chargeability high targets in carboniferous volcanics returned at and near surface copper-gold mineralization (highlights including IBEX006 with 18 metres @ 0.66% CuEq and 18 metres @ 0.75% CuEq in a trench). Subsequent ground magnetic indicated previous drilling occurred on the margin of an inferred Devonian target zone. Drilling in 2017 tested the geological model of a large ground magnetic anomaly under sediments and/or carboniferous overlying Devonian arc volcanics or augite basalt beneath the conglomerate marker previously intersected by IBEX.

The 5 holes for 2,080 metres drilled in 2017, coupled with improved geophysical interpretations, have outlined that cover within the targeted area of interest was deeper than expected and failed to confirm favourable sedimentary rocks and carboniferous overlying Devonian arc volcanics or augite basalt beneath a conglomerate marker.  The IP chargeability anomaly drilled with hole BT004 in 2017 returned background pyrite and chalcopyrite and appears associated with carbonaceous units. The “Red Button” magnetic high feature in the central northwestern section of the license remains untested.

Discussions with potentially deeper seeing IP system providers have commenced which could be the next systematic step for exploration activities at Bayan Tal by both providing better depth to basement information (TEM capacity) and improved quality IP.

Ulgii Khiid Massif Margin

During 2017, three holes for 1,346m metres were drilled testing inferred shallower porphyry targets based on ground magnetics on interpreted arc transverse structures. All holes encountered thicker than expected cover with magnetic bearing basalts explaining the targeted anomalies with age dating and fertility analysis not providing encouragement.

The general region in the Ulgii Khiid Massive is thought to be prospective for lithium and REE, with further select ground truthing proposed in the 2018 field season.
