Very respectable results from the drilling program, nice size mining claim, and in relatively stable and mining friendly Mexico.
The only thing I don't like about exploration stage companies is they have no income, and thus must sell shares to fund ongoing operations.
They are most likely years away from building a Mill (if they ever intend to), and more drilling may be required to prove up reserves sufficiently to attract a JV partner.
Those are some of the factors I look at. I didn't research them beyond looking at the Press Release, so share structure, management experience, and proximity to a mill plus other infrastructure should also be considered.
Good luck with them. I don't invest in exploration stage companies as a rule but perhaps somebody else could jump in and give another opinion.
