some info found in this presentation that might providing some missing links to the scoping study:
* Targeting mining and concentrate production Q1 2018
* Low capital requirements, fast payback and short lead time to production
* Current plant is pilot scale – can be upgraded to 300tpd (110,000tpa) but a larger full scale operation requires a new concentrator.
* Plant upgrade Estimated low capex to upgrade current plant – SRK Report.
* (old info) Upgradeable to 200 tpd (75,000 tpa) – SRK due diligence report (US$1M)
* +90% recoveries to concentrate
* Existing plant onsite – Targeting: ~110ktpa for 20Kt of Zn concentrate pa
* The metallurgical testwork indicates thatzinc recoveries of 90% to 95% could be obtained to produce a clean concentrate with contained grades of 55% Zn (from scoping study)
* Estimated ~2020 New Standalone plant: Targeting ~250,000 tpa
* Preliminary discussions with financing and off-take partners underway.
* Operating costs Comparison & estimates suggest opex will be low (tbc).
* Arena can elect to move to 80% of the Plomosas Project for an additional A$750,000 in cash + A$1,700,000 in shares
