The company mined 7000t of high grade ore (14.5% zinc and 6.5% lead) at the Plomosas operation in May and is aiming to reach 10,000t per month in the next month or two, with ore toll treated by a third party.

Production began last year and there have been teething issues.

That plus the softer zinc price sees ConsZinc's current capitalisation being little more than A$10 million.

Ultimately though, the belief is more than 500,000t of contained zinc (equivalent) can be defined, leading to development of a dedicated 500,000t per annum zinc and lead concentrator and potential annual earnings above US$30 million per annum.

Such is the prospectivity ConsZinc believes such resources could be defined over the next couple of years via exploration expenditure of as little as $5 million.

If the prospectivity is indeed realised ConsZinc MD Brad Marwood and his shareholders could be much happier than they are today, with Marwood strongly incentivised by his board to achieve a plus-A$100 million market cap by the end of 2021.

Still, it's all to do.

Shares in ConsZinc were trading at 1.1c this week, capitalising the company at about $12 million.

Meanwhile, the company is also said to be actively looking for a second project/operation that can utilise the company's skills and reduce the risk of being a single mine company.
