24 April 2019
KALAMAZOO COMPLETES INITIAL DRILLING IN WA’S DOOLGUNNA REGION
Highlights
-
Kalamazoo has completed a reconnaissance drilling program at its Cork Tree Copper Project in WA’s highly prospective Doolgunna region.
-
Five anomalous copper zones were intersected (>500ppm Cu), all located within E52/2057 at the Cork Tree Copper Prospect.
-
In one of the zones there was an intersection of anomalous copper across a significant 32m width at shallow depth.
-
Maximum copper values of 2,140ppm (0.21% Cu) recorded.
-
Kalamazoo will now follow up the composite sampling with resampling of onemetre splits in the copper zones of interest and planning the next phase of exploration.
Copper-gold exploration company, Kalamazoo Resources Limited (ASX:KZR) (“ Kalamazoo ”), today announced it has completed a preliminary reverse circulation drill programme at its Cork Tree Copper Project, located in Western Australia’s highly prospective Doolgunna region (Figure 1).
Four holes (19CTWRC001 – CTWRC004) were drilled for 624 metres at the Elmo and Cork Tree Copper Prospects, within E52/2056 and E52/2057 respectively. Hole details are recorded in Table 1.
The Cork Tree Project consists of six granted exploration licences (E52/2056, E52/2057, E52/3042, E52/3514, E52/3515 and E52/3540), comprising 117 blocks and covering a contiguous area of approximately 370km[2] along the contact of the Yerrida Basin and the Earaheedy Basin (Figure 2).
The exploration area covers 40kms of strike and is located 30kms to the south-east of the DeGrussa and Monty mines owned by ASX-listed Sandfire Resources NL (ASX: SFR) (Figure 2).

Figure 1: Location of the Cork Tree Project
Historical exploration at Cork Tree[2] has indicated very encouraging copper potential with a regional soil sampling program having defined an anomaly some 1,950m x 600m in extent with results ranging from 2ppm to 25ppm Cu. In addition, eight rock samples of ‘gossans’ have previously returned copper assay above 0.1% with a maximum of 1.42% copper.

Sampling
Samples were taken at one metre intervals but composited over four metre intervals with a duplicate every twentieth sample and a certified reference standard inserted every forty samples. A total of 156 composite and 12 QAQC samples were analysed by ALS in Perth for a 33 element suite by ICP Method ME-ICP61 after a four-acid digest: Ag, As, Ba, Be, Bi, Ca, Cd, Co, Cr, Cu, Fe, Ga, K, La, Mg, Mn, Mo, Na, Nb, Ni, P, Pb, S, Sb, Sc, Sr, Th, Ti, Tl, U, V, W and Zn. Further analytical details are provided in the JORC table appended.
Geology
The lithologies intersected in the drilling were generally a monotonous sequence of laminated to brecciated dolomite, dolomitic siltstone, laminated arenaceous siltstone, black pyritic shale and/or siltstone, with variable depths of intensive weathering.
At the Elmo Prospect, up to 2m of colluvium overlies a variably leached clay zone with abundant silica after dolomite to depths ranging from 18-32m and then increasingly fresh dolomite with minor interbedded siltstone. Minor quartz veining occurs sporadically, and traces of very fine grained sulphide (pyrite).
==> picture [596 x 98] intentionally omitted <==
==> picture [177 x 62] intentionally omitted <==
Near the Cork Tree Copper Prospect within E52/2057, hole 19CTWRC003 was positioned to test a weak moving loop EM conductor interpreted from a ground survey in 2016. One meter of soil and colluvium overlies intensively leached clays after argillaceous sediment, with very minor siliceous dolomite interbeds, to 58m vertical depth, underlain by strongly haematitic weathered argillaceous clays and minor dolomite to 148m before ending in grey weakly weathered dolomite. No fresh rock (such as carbonaceous shale) or sulphide source is evident for the EM anomaly.
Angled hole 19CTWRC004 at the western margin of the historic RAB drilling at the Cork Tree Copper Prospect was drilled to the south to undercut strongly anomalous copper in the first 20-30m of the weathered profile in the old holes. Strongly weathered clays and siliceous dolomite were intersected to 27m down hole, underlain by partially oxidised massive bedded dolomite to 47m and thereafter very weakly oxidised grey dolomite with occasional white quartz veining. A zone of oxidised limonite/haematite stained quartz veining occurs from 143-147m down hole.
Assay Results
There were five anomalous copper intersections of note (>500ppm Cu), all located within E52/2057 at the Cork Tree Copper Prospect, with three intervals reporting copper greater than 1,000ppm (0.1% Cu), with a maximum of 2,140ppm (0.21% Cu). There were no significant assays in the other base metals:
-
19CTWRC003 – 56m-88m: 32m @ 700ppm Cu with the highest individual assay being 1,300ppm Cu. Apart from Fe, with assays up to 20.6%, there are no other base metal or mineralisation indicator elements that are anomalous. This zone was logged as extremely haematitic and limonitic shale and chert (after dolomite), with up to 30% limonitic vein quartz in a probable shear zone.
-
19CTWRC003 – 144m–148m: 4m @ 660ppm Cu. Other than 1.01% Mn, there are no other anomalous elements. Logging indicates up to 30% vein quartz at the base of the haematite oxidation zone.
-
19CTWRC004 – 8m–28m: 20m @ 740ppm Cu with the highest individual assay being 1,240ppm Cu. Apart from Fe, with assays up to 27.5%, there are variably weakly anomalous Co, Ni, Pb and Mn assays. This copper anomalism is within intensely weathered surficial material, extremely limonitic and ironstone-rich.
-
19CTWRC004 – 128m–132m: 4m @ 630ppm Cu. The sample also assayed 3.6% Fe. From 126m to 132m the logging indicates quartz and feldsparrich (up to 80%) veins within grey-black shales/siltstone.
==> picture [596 x 98] intentionally omitted <==
==> picture [177 x 62] intentionally omitted <==
- 19CTWRC004 – 144m–148m: 4m @ 2,140ppm Cu. The sample also assayed 9.8% Fe and 0.15% S, the latter being slightly elevated relative to the other sulphur assays and this may indicate very low levels of copper sulphide – none was observed in logging. As noted above, the logging indicates an oxidised quartz vein zone (up to 80%) from 143m to 147m. No accompanying copper carbonates or oxides were observed.
A representative suite of multielement assays is shown in Table 2.
Discussion
Reconnaissance drilling at the southern end of the Elmo Prospect in E52/2056 has established that a substantial thickness of bedded dolomite bedrock underlies the extensive surface scree comprising siliceous boulders and breccias of secondary origin. No anomalous copper lead or zinc assays were recorded at the Elmo Prospect.
The source of the moving loop EM conductor located south east of the Cork Tree Copper Prospect in E52/2057 is not evident from the one hole completed. One possibility for the source is a structurally controlled ‘channel’ of deep weathering that has been shown to extend to at least 148m vertically.
Drilling below the shallow copper anomalies intersected in historic drilling at the western edge of the Cork Tree Copper Prospect has confirmed the anomalous response and an apparent association with strong clay weathering. Copper levels are generally lower in the underlying fresh bedrock except for a zone of oxidised quartz veining (143m-147m) that is associated with a 4m assay at 0.21% Cu from 144m-148m.
Next steps
Resampling of the anomalous copper intervals will be undertaken on a one metre basis together with the development of the next stage exploration program on the identified Cork Tree anomaly and its encouraging copper potential.

About Cork Tree Project
Kalamazoo’s copper asset is the Cork Tree Project, located 830km north east of Perth, 120 kms north-north west of Wiluna and 160 kms north east of Meekatharra, in the Mid-West region. It is situated within the Peak Hill Mineral Field, the Peak Hill (SG50-08) 1:250,000 map sheet and the Thaduna (2846) 1:100,000 map sheet. The project can be accessed from Meekatharra via the Great Northern Highway, then the graded Neds Creek Station road. It consists of six granted exploration licences. Access within the tenements is straightforward through relatively flat terrain using mining and exploration tracks.
Although the project is an exploration project some infrastructure exists in the area and reasonable proximity to Meekatharra and Wiluna provides access for some exploration supplies and services. Sandfire’s DeGrussa ore processing facility lies some 30km west of the project area.
