Research as a Service released a report back in April - prepared for the company that claims a 0.12 share price target based on them re-establishing zinc production from their single asset in Mexico.
7 June report stated they had a negative cashflow quarter and cash at hand is is down $133k from circa $800k in April.
Having seen "interest" in this one on Twitter I decided to take a look. When the price of zinc has increased 30% in the last 12 months, and a quick glance under the covers - its not one for me.
