The firm, according to its website, is developing multi-commodity exploration projects in Africa and it has made some big strides recently.
As well as lithium at Zulu, the group is developing the RHA tungsten mine in Zimbabwe, where serious production starts this year.
It also has assets in Mozambique and a stake in private firm Circum Minerals, which has a strategic holding in the Danakil Potash project in Ethiopia.
Circum has promised a 'liquidity event' sometime soon.
RHA and tungsten
The RHA deposit is around 800m in strike length and 300m wide, and the mine uses simple gravity techniques to extract wolframite (tungsten).
There have been issues along the way to get it up and running but these are being resolved, the firm assured.
In February it said the shaft upgrades at RHA have now been completed and the terms for the underground mining contract have now been finalised.
Mining contractor African Mining and Exploration will to deliver up to 16,000 tons of tungsten ore per month to the plant.
At the same time, final terms have been agreed to deliver up to 24,000 tons of tungsten ore from open pit operations per month, all commencing in March 2017.
"The conclusion of the final contractual mining terms is another important step on the path to commencement of plant operations at RHA where implementation of the XRT sorter and allied plant improvements continue on schedule with planned commissioning this quarter," said George Roach, chief executive.
“Re-optimisation of the open pit by Datamine presents an extended open pit life of up to 12 years and the simultaneous underground mining provides encouraging options for future developments.
“Shaft upgrades are now paid for, as is the case with the XRT sorter that has been upgraded to latest specifications by the manufacturer and is expected to leave South Africa for delivery to site this week."
Zulu and lithium
At Zulu, significantly regarded as potentially the largest undeveloped lithium bearing pegmatite in Zimbabwe, drilling has been undertaken via a 20 hole programme -aimed at producing a maiden resource and testing extensions to the 3.5km surface strike length.
Latest assays indicated more good lithium grades.
One hole saw grades up to 3.3% Li2O (lithium oxide) over almost 30m with more than 2% was intersected in another hole, while previously unreported mineralisation in the host rock was also identified.
Premier is now planning more drilling to determine the ultimate size of Zulu.
Lenigas a consultant
Meanwhile, David Lenigas, a veteran of the resource sector and small cap promoter, is involved as a consultant to carry out an independent review for the project - looking at potential strategic investors or joint ventures as well as financing.
Roach told Proactive he was very excited at Lenigas's appointment and believes that Zulu has "world scale potential written all over it".
House broker Shore Capital noted that so far, lithium-bearing pegmatites have been identified over a strike of around 3.5km to vertical depths of over 200m, with true widths of 10-25m.
"On the basis of historical and more recent work by the company, PREM believes (quite reasonably, in our opinion) that Zulu has ‘company making’ potential, with a potential scale comparable with that of other world-class spodumene/pegmatite deposits," it added.
A limestone deposit in Mozambique....and forestry
Other interests include the Catapu forestry deposit that lies near the railway in the Sofala province, which the firm bought via its purchase of a 52% interest in a Mozambique firm, which also holds a 24,821 ha hardwood forestry concession.
Premier plans to start an initial exploration and assessment work programme on the limestone deposit, which is expected to provide a maiden resource and preliminary scoping study late this year. The exploration programme is fully funded.
Premier has four assets - the Pagala zinc exploration project; the Haito nickel project, the Kara - Niamtougou uranium site and the Dapaong gold project.
Also worth noting in Zimbabwe, the firm has the Katete project comprises 25 claim blocks prospective for Rare Earth Elements (REE). It is also investigating a 1,350-hectare area centred on the dormant Tinde Fluorspar mine and has the Lubimbi rare earth project.
