Fertoz Confirms Continuous High Grade Phosphate at Wapiti East in 60 Holes – Open at depth and along strike
November 19, 2013 (Source: Fertoz Ltd.) — Highlights:
- Consistent and continuous phosphate-bearing horizon drilled and mapped along East and West Limbs for a total of 17 kilometres of strike length
- Potential strike length based on past results is in excess of 27 kilometres
- Bulk sample (2 tonne) taken averaging 24.3% P2O5 with low impurities
- Permit application submitted to collect up to 6,000 tonne bulk sample in first quarter 2014 for farm trials and customer sales
Summary of Results
Fertoz Ltd (“Fertoz” or the “Company”) is pleased to announce phosphate results from its Wapiti East project in British Columbia, Canada.
The Company completed 2,098 metres of diamond drilling (62 drill holes) at Wapiti East between August and October. Fertoz also collected a two-tonne bulk sample.
Preliminary assays showed low impurity level and high phosphate (P2O5) grade.
Les Szonyi, Managing Director, said, “We plan to extract up to 6,000 tonnes in the first quarter next year from Wapiti East and trial the product in the organic fertiliser market. This drill program identified high grade areas that are amenable to low cost mining methods. Wapiti East is close to rail transport corridors that traverse Canada and head into the United States of America, the largest agricultural market in the world. Both countries have huge potential for organic fertilisers.”

Drilling at Wapiti East confirmed a mineralised zone that was relatively uniform and regular in orientation. Drill spacing varied and was reduced to 20m intervals to confirm short term continuity in the sections. The mineralised zone remained open at depth with the mineralised phosphorite zone typically intersected at 90° to core axis, between 1.2m and 2.25m true width. The average grade varied between 13% and 27% P2O5 over this width.
A two-tonne bulk sample was collected and assay results submitted to AGAT Laboratories in Ontario. The results, summarised in Tables 1 and 2 below, show the product has trace heavy metal impurities (arsenic (As), cadmium (Cd), cobalt (Co),mercury (Hg), lead (Pb), selenium (Se), zirconium (Zr) and uranium (U)) , which is a pre-requisite for use in the organic fertiliser market, whilst also providing sufficient levels of macro and micro nutrients. Calcium (CaO), potassium (K2O), magnesium (MgO) and phosphorus (P2O5) are macronutrients; iron (Fe), copper (Cu), manganese (Mn), molybdenum (Mo), zinc (Zn) and nickel (Ni) are micronutrients; both are required for plant growth. Very low levels of various oxides including aluminium (Al2O3), barium (BaO), chromium (Cr2O3), magnesium (MgO), titanium (TiO2), strontium (SrO) and vanadium (V2O5) and low levels of silica (SiO2) are preferable for organic fertilisers.

Further work on Wapiti East is planned including:
1. Geochemical testing to determine free phosphate content, particle size and the minimum phosphate grade which is suitable for direct application as an organic fertilizer. The cut-off grade to achieve this is yet to be determined. Economic cut-off grade will determine the volume of mineralisation at Wapiti that is potentially available for resource classification.
2. Permitting to collect up to 6,000 tonne bulk sample in the first quarter of 2014. The bulk sample is planned to be used for product trials with potential customers followed by initial sales.
3. A larger bulk sample is planned for the second half of 2014.
Detailed Analysis of Results
The 2013 drilling campaign focussed on three areas along two main phosphate ridges as shown in Figure 1 below. The initial focus was the west limb (Area 1) of the Red Deer Syncline where there are several parallel phosphate zones. The phosphorite zone in the West Limb of the Red Deer Syncline structure is extremely uniform over the strike length tested. It appears that the structural stresses on the West Limb horizons have largely been localized in a persistent mylonite zone and the phosphate mineralization is relatively undeformed. The West Limb Zone has a strike length of 340m drilled but when combined with mapping along the open well-defined synclinal fold of mineralisation which connects Area 1 and Area 4 in Figure 1, the total strike length is approximately 9km.
The phosphorite zone on the East Limb of the structure is also very uniform. The East Limb horizon was also duplicated in some drill sections resulting in localised thickening of mineralised horizons. Area 2, on the northern part of the East Limb of the Red Deer Syncline, was drilled to gain further information about the main phosphate seams running throug h the property. Area 3 was the focus for a small bulk sample of approximately 2 tonnes. The area drilled on the East Limb was 2.7km (Area 2 to Area 3). The entire mapped known length of the East Limb is approximately 8km (Ref. Cardinal DG, National Instrument 43-101 Technical Report on the Wapiti Phosphorite project , 10 February 2013).
The strike length for both the West and East limbs is open to the north and south. The potential strike length of the Wapiti East deposit, based on past results, is in excess of 27 kilometers (Ref. Cardinal DG,
National Instrument 43-101 Technical Report on the Wapiti Phosphorite project , 10 February 2013).
Phosphate was identified by a portable Niton XRF in all 60 effective drill holes (2 holes stopped short) and 352 drill core and channel samples were selected for laboratory analysis. Holes varied from 13m to 75m in depth, mainly –
45° and -60° inclination while hole spacing varied from 20m to 200m. Two holes were completed on each site set- up (section) to give added confidence on the accuracy of the three dimensional orientation and thickness of the phosphorite horizon. The phosphorite horizon outcropped on the surface and extended to a straight vertical depth of 35m with the phosphorite zone still open at depth.
The drilling on the West Limb (North) was designed to be close spaced in order to quantify the along-strike continuity of the phosphorite horizon. The mineralized zone turned out to be extremely regular and predictable both along strike (drill set-up spacing varied from 20m to 40m) and also down dip.
The mineralization is generally below a black shale-siltstone sequence and mylonitic shear zone with high grade layers and lower grade areas of phosphate.
Les Szonyi said “The Fertoz strategy is to define smaller resources that can be commercialised quickly with low capital expenditure, to generate cash flow for the Company. Drilling at Wapiti East has identified such a resource and the Company is focussed on moving to the next stage of a larger bulk sample and customer trials.”
