Drilling Identifies High Grade Gold Mineralisation at East Burtville Prospect
- Drilling identifies high grade gold mineralisation
o 8 metres at 6.7 g/t gold
o 4 metres at 5.1 g/t gold
- Mineralisation associated with extensive quartz veining that extends north and south of drill intersections
- Mineralisation starts at surface and is open at depth and along strike
The Company recently completed a 733 metre drilling program targeting significant gold mineralisation identified in historical exploration and mine workings.
The current drilling identified high grade gold mineralisation including:
- 8 metres at 6.7 g/t gold from surface
- 4 metres at 5.1 g/t gold from surface
- 4 metres at 3.4 g/t gold from 40m within quartz veining
- 8 metres at 0.68 g/t gold from 72m within quartz veining
The gold mineralisation is associated with a north-south trending quartz vein occurring within metamorphosed basalts. The quartz vein is exposed at surface and has been intersected in drilling over a strike length of 100 metres and is open along strike and at depth. Intersections from historic drilling also intersected high grade gold mineralisation associated with quartz veining including:
- 5 metres at 27.8 g/t gold including 1 metre at 135 g/t gold
- 2 metres at 6.7 g/t gold and;
- 3 metres at 5.3 g/t gold.
The Company has collected the single metre sample intervals for analysis and will plan further drilling once these assays have been received and reported.
Managing Director Todd Hibberd commented that "The East Burtville prospect has great potential to host a high grade gold deposit that is amenable to open pit mining. The quartz vein has been identified over 100 metres of strike and 80 metres depth with some very attractive grades. The Laverton region has several mills that are within haulage distance so a small open pit-toll treatment operation is a distinct possibility. Once the one metre samples have been received and evaluated the company will plan further drilling".
East Burtville Drilling Identifies High Grade Quartz Vein
The recent RC drilling targeted a quartz vein identified by historical exploration and mine workings. The quartz vein is sub-vertical and trends north south and is 1-5 metres wide occurring within mafic schist (metamorphosed basalt). Prior to drilling the orientation of the quartz vein was unknown so drilling tested several possible orientations. Of the 17 holes completed, the quartz vein or shear zone was intersected in 5 holes (BEAC 1-5) confirming the north-south orientation.
Historical drilling (MLJC-36 and MLJC-31) intersected the vein/shear zone along strike north and south of the main drilling. Both contained quartz and alteration but no gold mineralisation. The Company notes that the nature of gold deposition in quartz veins can be very discrete with the gold occurring in plunging shoots or as isolated nuggets with no gold in the adjacent quartz. The Company is very encouraged by the presence of the quartz veining and believes further drilling is warranted.
East Burtville Background
The Company acquired the East Burtville Prospect in 2011 as part of the Merolia Gold and Nickel project. The prospect occurs in the north-westerly trending Merolia greenstone belt which is interpreted to form part of the Laverton greenstone belt. The geology is typically basalts, ultramafic and felsic volcanic rocks that have been metamorphosed to green schist facies.
Mineralisation occurs as quartz veining in metamorphosed basalts which trends north-south and is sub-vertical. The vein has been identified over 100 metres via drilling and is untested along strike and at depth.
A vertical mine shaft and associated mine workings (circa ~1992) were constructed based on some high grade gold intersections in historical drilling. No production records are available for the small scale mining operation but extensive re-sampling of the ore stock piles and waste dumps have produced some spectacular grades up to 38 g/t in channel samples. The remaining ore stockpiles contain economic levels of gold mineralisation (see ASX release Dated 20th October 2016).

About White Cliff Minerals Ltd
White Cliff Minerals Ltd is a Gold, Copper, Cobalt, Nickel resources and mining company listed in Australia (ASX:WCN). The Company is focused on developing low cost high value mineral deposits that have near term cash flow potential.
Major projects include the Aucu gold deposit that contains 484,000 ounces of gold (3mt at 5.1 g/t) starting at surface and Chanach copper deposit that contains 64,000 tonnes of copper (17.2Mt at 0.37% copper). Both projects have substantial blue sky potential with drilling covering only 5% of the known structures. In Australia the company is developing the Coronation Dam cobalt–nickel deposit where a maiden resource will be announced in the late 2018.
