Shining Tree Gold

Highlights of Recent Activities

Since June of 2016 after a four year hiatus, Platinex has recommenced activities on the Shining Tree project. A resource valuation has been commenced on the Herrick gold deposit in order to establish a NI43-101 compliant resource including consideration of an open pit. Planning is underway to determine the supplementary exploration necessary on the Herrick deposit. Logging and sampling of core obtained in a 2012 drilling program to initially test gold in till anomalous indications has now been completed. Staking and strategic acquisitions was conducted through to June 2017 with a 500% expansion of the property to a size of 35,000 acres (14,000 ha).  The acquisition activities enabled coverage of a 21km strike length on the Tyrell-Ridout Deformation Zone, a probable source for some of the gold in till anomalies.

Exploration Highlights to date

Spectacular gold counts in glacial soil along nine kilometres strike length highlights the discovery status of this zone on the Shining Tree gold property. Figure 2 & 3 show comparisons of Timmins and Matachewan till results to Shining Tree and demonstrate how all of the multimillion ounce Matachewan or a large part of the Timmins camp might fit into the Shining Tree property. Historically a total of 60 holes have now been drilled on the Herrick deposit which remains open along strike and at depth.

Gold in Glacial Till

Sampling of the basal till has revealed spectacular gold contents along the length of a nine kilometre shear zone on the property. Of 430 samples analyzed and normalized to date 173 contained 10 or more gold grains, 14 contained more than 50 gold grains and three contained over 100 gold grains. The pristine grain counts are high in most cases and indicate a nearby source. Partial analyses of the fine fraction of 88 till samples revealed systematic property-wide evidence of associated mineralization correlating with high gold counts.

A major discovery in place appears to be in the offing.  Effective Gold Prospecting In Glacial Till explained. Slide Show – Till Geochemistry and Indicator Mineral Methods for Exploration in Glaciated Terrain.

On a regional scale the property is located within the prolific Abitibi greenstone belt which is renowned for its concentration of world-class gold and Cu-Zn-Ag-Au deposits. The Shining Tree property is underlain by the Tyrrell-Ridout Deformation Zone with which several world-class gold deposits are spatially associated. The Shining Tree property is also centred on the axis of a regional gravity high signifying an area of thick supracrustal rocks and under-plating by oceanic crust.  In the Abitibi these associations are conducive to the discovery of major gold deposits.  In fact the Shining Tree property is situated on the strongest gravity anomaly in the entire gold belt of several hundred kilometres length.

The property is underlain by an Early Precambrian assemblage of WNW trending, steeply dipping felsic to mafic and ultramafic metavolcanic rocks as well as metasedimentary rocks and alkali metavolcanic rocks of Porcupine age. These rocks are intruded by pre-orogenic feldspar porphyries and hypabyssal diabase dikes and sills of Nipissing Age. The Porcupine or Timiskaming aged metasedimentary rocks are believed to have accumulated in a regional rift. Later south to north compressive faulting along the axis of this rift has been proposed. Major NNW sinistral wrench faults, including the Michiwakenda Lake Fault which crosses the Shining Tree property, are regional in scale. Related subsidiary parallel shears and possible splays carry significant gold mineralization on the Shining Tree property.

Bedrock exposures are limited on the property which is principally covered by a thin mantle of Wisconsinan till.

Portions of the property display a tellurium-silver-gold association in which very high grade gold occurs within N085°E shears (Caswell). In other portions of the property the same structures display a gold-arsenic association. Some of these shear zones are cataclastic and even mylonitic.  The N085°E shears intersect a system of north northwesterly trending thin sheared interflow metasedimentary rocks which host quartz veinlets and veins.

Current work on the property is assessing the chemical affiliations especially through a till sampling program.  The chemical composition of the till appears to reflect the bedrock chemical signature. With the high pristine gold grain counts being obtained in the till it is expected that additional in situ gold will be located with follow up exploration.

The Caswell prospect was initially evaluated by Platinex in the fall of 2010 with a surface sampling program comprising 370 channel samples and 4 grab samples. The prospect is underlain by two north northwesterly trending shears within interflow metasedimentary units and 39 documented N085°E mineralized shears.

Herrick Gold Deposit

From 2009 to March of 2011, Platinex has drilled 51 holes for 6,190m on the Herrick deposit.  All of the holes have returned good gold values and the deposit has been tested along an 400m strike length and to 300m depth.  It is open in all directions.  Results are tabulated herein and an independent resource valuation may be completed in the fall of 2017.

The Herrick gold deposit discovered in 1918 has been developed by a shaft to 94 metres and some 345 m of lateral development.  Very high grade shoots were defined in surface channel sampling, sampling in the shaft, underground on the level at 90 m and in four drill holes by Herrick Gold Mines from 1918 onwards. In 1989 Unocal drilled 11 holes for 1,473m, cut over 201 channel samples and also took 35 composite grab samples on the two veins to test a stated potential, solely from historic data, of the system to carry 1,732 tonnes per vertical foot at 7.2 g Au /t over a width of 1.8 m and 50% dilution.

Unocals’ results confirmed the persistence of the gold mineralization over a 385 metre strike length and expanded the known thickness of the mineralized shear along much of its length. However, the drilling and channel sampling by Unocal and Platinex identified that certain gold-bearing zones are narrowly confined within the shear zones and carry potentially commercial, high grade, correlative values and other portions contain isolated patches of high gold grades within a broader lower grade shear zone.

Although the tenor of the Herrick Gold Mines drill core and channel sampling was not confirmed completely, the location of the mineralization was confirmed by Unocal. Surface sample gold values of up to 56.5g per tonne /1.0 m (45 samples) were reported. In 1990 Fort Knox Mines performed a small program of channel sampling on surface and in the shaft confirming some of the higher grade mineralization but not all of the higher grade values presented by Herrick Gold Mines in 1919.

In 2008 Platinex initiated its Phase I program of exploration. Work included: an airborne magnetometer, VLF-EM and radiometric survey; stripping, channel sampling (58 samples) and core sampling conducted to verify results of previous work on the Herrick, Caswell and Churchill workings.

Work by Unocal and Fort Knox Gold on the Herrick vein was qualified and validated. Furthermore, portions of the Herrick Gold Mines channel samples have been found to be consistent with later sampling.

Ronda Gold Mine

The Ronda Mine, mined the Ribble quartz vein located partially within a portion of the Platinex Shining Tree claims (Fig. 9).  The vein was reported to have a north strike and 60o west dip is exposed almost continuously for 440 metres and had an average width of 1.5 metres. Two shafts and six levels developed a small portion of the vein with production mainly from the fifth level and upwards. Recorded production occurred only in 1939 and amounted to 2,727 oz. gold and 4,830 oz. silver from 24,592 tons for an average recovered grade of 0.11 oz. Au per ton in 1939. The mine was closed due to the beginning of the war and the resulting shortage of labour and has never reopened.

The northern half of the Ribble vein is projected to enter the Platinex Shining Tree property at a depth of approximately 235 m (Fig 9 and 10). Drill hole R96-06 drilled by Strike Minerals is reported to have tested the Ribble vein and a parallel vein with positive but unqualified results at vertical depths of 215m and 250m.  Platinex claims also cover the southern portion of the Ronda underground workings.

Platinex plans deep drill tests on the Ronda vein (Fig. 10) as high priority targets.
