Some healthy results starting to emerge, moving from South-East to North-West direction;
TR007 has basically 5 separate zones under the existing pit with the best being 1m at 23.34g/t from 37m.
TRC025 and TRC026 (75m along strike), there is a pretty obvious 3 separate zone are there for a combined ~8-12m of mineralisation, they just need to be infill drilled and drilled at depth to confirm.
TR029 (150m along strike from TR026), we can see it continues at high grade close to surface in at least 2 of the zones for a combined ~7m of mineralisation.
It’s not a easily predictable system! The zones vary in grade, widths and directions, however a lot of infill and extension drilling required in Stage 2 will reveal the system for modelling.
However some quick back of paper calc’s;
TR007 to TR029 is about 375m and with an open pit down to 100m depth to capture what we ‘know’. Take 375m * ~10m of mineralisation and down to 100m depth we should have around 375,000m3 of material, or around 900,000t of material using these basic back of paper assumptions. The grade varies considerably, but there is lots of good material within about 50m of surface which will be easily extracted, the deeper material will need a large strip ratio to get at and extract.
TRY could develop a 50-60m deep pit down to the ‘fresh-rock’ or just a little into it for ~400m strike and extract the higher grade (10+gpt) material from surface, there would be about 400,000t of material with a heavy strip ratio, perhaps not so bad for 125,000oz+ can be achieved. The deeper stuff might require a higher gold price for a pit wall cutback, again, not so bad, drop a few deep holes to see how grade looks. If grade exploded at depth in the fresh rock then an underground future option could be a goer... but deep drilling is expensive, so TRY are better off searching <100m of surface for 2019 IMO.
Extension drilling will be interesting, how far does it go along strike…
