    Encounter Resources intersects bedrock gold in Tanami

    Encounter Resources Ltd (ASX: ENR) has announced a highly encouraging update on the drilling activities in the Tanami region of WA, held in a joint venture with Newcrest.

    The company reported that the initial results from first pass RC drilling at the Afghan and Mojave prospects by JV partner Newcrest Mining in the Tanami Province identified bedrock gold mineralisation and geological controls at both prospects.

    ENR said that the mineralisation is hosted by structures developed within folded dolerite units, which are a favourable host for orogenic gold mineralisation.

    ENR said that one section of three RC drill holes was completed at Mojave.  The company said that multiple, broad zones of bedrock gold mineralisation were intersected in drill holes MOJ002 and MOJ004 at Mojave which remains open along strike and at depth.

    Significant intercepts from MOJ004 includes 16m @ 0.27g/t Au from 36m; 4m @ 0.25g/t Au from 56m;  6m @ 0.47g/t Au from 66m; 8m @ 0.30g/t Au from 76m; 10m @ 0.69g/t Au from 228m; and 10m @ 0.38g/t Au from 256m.

    Important hits from MOJ002 include 4m @ 0.70g/t Au from 20m; 4m @ 0.28g/t Au from 124m; 6m @ 0.53g/t Au from 174m; 4m @ 0.38g/t Au from 196m; and 10m @ 0.34g/t Au from 210m.

    The company said that the results from an eight-hole broad-spaced RC drill program at Afghan have confirmed gold mineralisation over a 2km zone.

    Highlights include 10m @ 1.6g/t Au from 4m incl. 6m @ 2.5g/t Au from 6m; 2m @ 2.0g/t Au from 40m & 2m @ 3.5g/t Au from 136m; and 24m @ 0.32g/t Au from 102m.

    The company reported that the planned 2020 exploration for the Tanami and West Arunta JVs will be finalised in conjunction with Newcrest Mining Ltd in early March 2020.

    JVs with Newcrest

    Encounter resources is advancing a highly prospective suite of projects in the Tanami and West Arunta regions via joint ventures with Australia’s largest gold miner, Newcrest Mining Limited.

    Tanami is one of Western Australia’s most prospective gold districts. Encounter controls exploration tenure of 4,200km² in the Tanami region in WA.

    Newcrest is sole funding exploration activities across a series of joint ventures with Encounter in the Tanami and West Arunta regions of WA.

    Three of these joint ventures (Watts, Selby, and Lewis) cover over 100km of strike along the major structural corridor (Trans-Tanami Structure) that extends through the Tanami region of WA.

    Mojave as well as Afghan prospects are located in the Selby JV.

    The Mojave prospect is located within a 7km NW trending corridor of arsenic anomalism (As >100ppm). Two discrete zones of known gold anomalism (>0.1g/t Au), named Yosemite and Mojave sit within this regionally significant anomaly.

    Drilling at Tanami

    The company had commenced drilling at the Mojave prospect and Afgan prospect of the Tanami region of WA.

    The company reported that one of three planned drill traverses was completed at Mojave before the end of the 2019 field season. ENR said that the results from the three holes (900m) drilled on this section have confirmed strong bedrock gold anomalism within a folded dolerite unit, confirming the interpreted geological model.

    The company said that two steeply dipping mineralised structures are associated with minor quartz sulphide veining along the limbs of an interpreted antiform and these remain open along strike and at depth.

    At Afghan prospect, a total of eight RC holes for 2,292m across five broad spaced sections were completed along a 2km section.

    The RC drilling at Afghan targeted the down dip and plunge extensions of a 4km long supergene gold anomaly identified by previous explorers.

    Multiple zones of gold mineralisation at Mojave

    The company announced that the drill holes MOJ002 and MOJ004 intersected multiple zones of gold mineralisation within the dolerite host.

    Significant intercepts from MOJ004 include 16m @ 0.27g/t Au from 36m; 4m @ 0.25g/t Au from 56m; 6m @ 0.47g/t Au from 66m; 8m @ 0.30g/t Au from 76m; 10m @ 0.69g/t Au from 228m; and 10m @ 0.38g/t Au from 256m.

    The results from MOJ002 include 4m @ 0.70 g/t Au from 20m; 4m @ 0.28 g/t Au from 124m; 6m @ 0.53g/t Au from 174m; 4m @ 0.38g/t Au from 196m; and 10m @ 0.34g/t Au from 210m.

    Prime target for future drilling

    The company noted that Mojave results are particularly encouraging as the hinge zone of the interpreted antiform is untested along strike. Such positions represent a key target for large zones of gold mineralisation in the Tanami, making it a high-quality target for future drilling.

    Encouraging results from Afghan drilling

    The company reported that the results from the Afghan drilling program have confirmed the presence of near surface supergene gold mineralisation including 10m @ 1.6g/t Au from 4m incl. 6m @ 2.5g/t Au from 6m (hole AFG002)

    The company said that the drill program provided the first deep drilling at Afghan and intersected bedrock gold anomalism within a folded dolerite unit including 2m @ 2.0g/t Au from 40m & 2m @ 3.5g/t Au from 136m (hole AFG005); and 24m @ 0.32g/t Au from 102m (hole AFG008)

    The company noted that the RC hole AFG008 was a single hole drilled on the most eastern section of Afghan and mineralisation in this hole remains open on section and to the east.

    Updates and future plans

    The company reported that the planned 2020 exploration for the Tanami and West Arunta JVs will be finalised in conjunction with Newcrest in early March 2020.

    Management comments

    Encounter Managing Director Will Robinson said: “The first pass RC drilling at the Afghan and Mojave prospects in the Tanami has confirmed historical near surface gold and intersected new zones of gold anomalism within tightly folded dolerite bedrock.

    The level of bedrock gold anomalism at Mojave potentially represents a halo to a higher-grade, orogenic gold deposit and the primary structural target located south-east remains open and untested.
