A few sour grapes,
But people getting in at these levels have significantly less risk,
Also their new Tin Process seems very promising:

The Taronga test sample, which was obtained from the surface outcrop of the Northern Ore Zone,
was initially crushed to 100% passing 32mm by conventional crushing, then crushed in one pass by a High Pressure Grinding Roll (HPGR).
The purpose of the test work was to determine if Taronga ore could be successfully upgraded after being crushed through a HPGR. The Company is pleased to report that initial test results are highly encouraging. The test was commissioned to determine whether the HPGR, which promotes crack propagation, could be utilized to crack the Taronga rocks along the fracture planes which contain approximately 90% of the tin in the ore. Further, it was expected that tin crystals exposed by the “cracking” would then be dislodged, making the tin available for conventional gravity separation, with:
 the finer fraction containing the enhanced tin values treated further.
 the remaining rock (coarser fraction) containing low tin values retained for further study into the potential recoverability of by products such as silver and copper, both of which are present in the Taronga ore.

The benefits of treating the Taronga ore in this way are twofold:
1. After the HPGR treatment, most of the contained tin (in this test, 62% of the tin) is found in a much smaller percentage of the original mass (in this test, 29% of the mass).
Potentially this has important implications for the operational and capital costs associated with ore processing.
2. The project will only be required to treat a much smaller percentage of the original mass. The project also benefits because the fraction that contains most of the tin is the -1mm fraction. Subsequent work by the laboratory in Perth proved that this fraction is amenable to tin recovery by gravity means. In a normal hard rock treatment plant, the crushing stage only reduces the ore size to -10mm to -15mm. The crushing stage is then followed by a grinding stage which reduces the ore further to liberate the valuable mineral, so that it can be recovered. In this case, the HPGR has done most of this work before the grinding stage, substantially reducing the overall capital cost of the treatment plant as well as reducing the operating cost profile

This is all positive for AWN....
