VANCOUVER, BRITISH COLUMBIA–(Marketwired – Oct. 10, 2013) – Kaminak Gold Corporation (TSX VENTURE:KAM) today announced the drill discovery and delineation of a new oxide gold zone on the Company’s Coffee Gold Project referred to as “Sumatra”. Drilling successfully identified shallow, oxidized gold-bearing structures over 500 metres (m) of mineralized strike with highlights of 15.78 grams per tonne gold (g/t Au) over 3.05m from 1.52m downhole in CFR0513 and 5.72g/t over 4m from 75m depth in CFD0331. The Sumatra Zone is associated with a northeasterly trending gold-in-soil anomaly (>1km in length) and an aeromagnetic lineament (>2km in length) interpreted to connect to the western extension of the Latte Zone and the western edge of the of the Supremo Zone. The 2013 Coffee drill program is ongoing and over 50,000m have been drilled so far this year.

Gold in oxidized mineralization is usually easier and cheaper to extract because the weathering of sulfides effectively liberates the minute gold particles from sulfide mineral grains. This exposes more particles to the cyanide and/or acid solution during extraction, which in turn allows more gold to be dissolved. When trapped in sulfides, roasting of the mineralized material is normally required to free the gold. This requires energy, which is an additional cost best avoided. Since the gold in oxides can be extracted at a lower cost the cut-off grade for gold hosted in oxides is generally lower. Kaminak is using a cut-off grade of 0.5 g/t for oxides and 1.0 g/t for gold hosted in sulfides.

Kaminak may be thinking that processing and extracting gold from oxide zones it may provide some early cash flow to fund later developments.

The Coffee Gold Project is located in the emerging White Gold District of the Yukon Territory, Canada. Below is a map showing the project’s location.

Eira Thomas, CEO, commented: “The Sumatra discovery demonstrates continued success in drilling gold-in-soil anomalies on the Coffee property and highlights the prospectivity of more than 25 km of untested, priority gold-in-soil anomalies that remain throughout the property.”

About the Sumatra Zone

Drilling targeted a 1.2km northeast striking +25ppb gold-in-soil anomaly located approximately 0.5km north of Latte and west of Supremo. Drilling intersected two separate, variably oriented mineralized structures:

  1. A NE-SW striking structure parallel with the aeromagnetic lineament, dipping steep to moderate to the NW. Highlight drill intercepts to date include: 0.99g/t over 30.48m from 135.64m depth in CFR0499, which is interpreted to have drilled obliquely down the structure, and 1.54g/t Au over 16.77m from 4.57m in CFR0514. Mineralization is interpreted to extend over at least 500m strike length and remains open along strike to the southwest beneath un-drilled gold-in-soil anomalies. To the northeast, it merges into the Supremo T1 Zone.
  2. An E-W striking structure, dipping steeply to the south. Highlight drill intercepts to date include: 15.78g/t Au over 3.05m from 1.52m, 5.26g/t Au over 9.14m from 22.86m, and 6.78g/t Au over 4.57m from 51.82m in CFR0513, which is interpreted to have drilled obliquely down the structure; 5.72g/t over 4m from 75m depth in CFD0331; and 3.86g/t Au over 6.09m from 132.59m. Mineralization is interpreted to extend over at least 600m strike length and remains open along strike to the west beneath the un-drilled portion of the gold-in-soil anomaly. To the east, it intersects with the Supremo T2 Zone.
Provided that the gold-in-soil anomalies are in situ occurrences, the strategy of first locating geochemical anomalies through a detailed soil sampling survey followed by a targeted drilling campaign is a sound methodology. Many ore deposits have been found this way. The reason being that soils of a residual origin are derived from the weathering of underlying rock. So, there is often a direct geochemical link between soil and the underlying material. There are exceptions though. Geochemical soil sampling can at times be unreliable, where under the action of gravity, ice, water and wind, soil has been transported from its original site of formation. This can produce anomalies that are not related in anyway to the underlying rock.
Below, we’ve provided a couple of relevant cross-sections obtained from Kaminak’s corporate website. They show how Kaminak determined that drill-holes CFR0499 and CFR0513 intersected the mineralization obliquely.

Approximately half of the 1.2km Sumatra gold-in soil anomaly remains undrilled. Both structures are open to the west beneath strongly anomalous gold-in-soils, which extend over 600m along trend then terminate at a zone of permafrost, which renders soil sampling ineffective. Interpretation of the magnetic data suggests the underlying bedrock structure continues for an additional 800m to the southwest before merging with or intersecting the Latte Structure, and therefore, represents a high priority exploration target.

The trick is to find the high grade zones within the mineralized structure. It is unlikely that the entire length of the mineralized structure has the same grade. Mineralizing fluids normally find preferred pathways or conduits along a structure. This results in localised regions of higher grades within predominantly lower grades. This uneveness in the gold anomalism is evident in the soil geochemistry map that we obtained from Kaminak’s corporate website. See below.

* True width estimated at approximately 2/3 down-hole length.
** Intercept drilled sub-parallel or oblique to strike of mineralized structure.

Not too many companies come clean on the issue of apparent vs true thicknesses. Kaminak deserves a pat on the back for saying that some of their drill holes were drilled obliquely down the structure giving apparently thick mineralized intervals of up to 30 metres.
