  • New resource estimate based on drilling completed to date to be finalised by early April 2017, with the Gorno Definitive Feasibility Study (DFS) on track for completion by the end of April 2017.

  • Plant design being undertaken by GBM Minerals Engineering Consultants close to completion and awaiting final metallurgical results.

  • Discussions continuing with potential financiers and off-take partners.

Energia Minerals Ltd (ASX: EMX; “Energia” or Company) is pleased to report further strong results from ongoing resource drilling and feasibility work at its flagship 100%-owned Gorno Zinc Project in northern Italy where latest drilling has further defined the flagship Colonna Zorzone deposit, which still remains open in several directions, ahead of a new resource estimate which remains on track for completion by early April 2017.

The updated resource will be based on the drilling completed to date and will underpin the Definitive Feasibility Study (DFS) due for completion by the end of April.

In the upper levels of the Colonna Zorzone Deposit, recent drilling has produced some impressive intersections outside of the currently defined resource.

Hole GDD134 intersected 78.6m grading 2.8% Zn+Pb, 10 g/t Ag , including 17.3m grading 7.7% Zn+Pb, 28 g/t Ag while GDD130 intersected 20.1m grading 3.9% Zn+Pb, 16g/t Ag including 10.1m grading 6.5% Zn+Pb, 22g/t Ag .

These two holes, together with a third (GDD146), for which assays are not yet available, are expected to increase the resource in this area. However, it should be noted that these intersections were drilled at a very low angle to the mineralisation and the true widths are therefore likely to be less than 10 metres.

The latest assay results from the Exploration Decline drilling program include intersections of 3.1m grading 8.5% Zn+Pb and 61 g/t Ag in GDD122, 2.9m grading 7.9% Zn+Pb and 33 g/t Ag in GDD127, 3.4m grading 6.1% Zn +Pb and 19 g/t Ag in GDD131, 4.9m grading 9.9% Zn+Pb and 103 g/t Ag in GDD132 and 10.2m grading 3.4% Zn+Pb and 21 g/t Ag in GDD135.

The 4.9m intersection in GDD132 was followed by an additional 6.0m with less than 5% core recovery which assayed 6.8% Zn+Pb and 142g/t Ag, followed by another 0.7m with excellent core recovery assaying 13.1% Zn+Pb and 216g/t Ag. As there are significant concerns regarding the reliability of data within this 6.7m section, only the first 4.9m grading 9.9% Zn+Pb and 103g/t Ag is being considered for resource modelling. A replacement hole, GDD132A for which assays are awaited, was drilled 15m to the north east of GDD132 and encountered approximately 6m of visually similar mineralisation to that intersected in GDD132 with no core loss.

Assay results from a further eleven holes (including GDD132A) are awaited and will be included in the new resource statement.

Although drilling to be included in the DFS has now been completed, the deposit remains open in a number of directions and drilling is continuing with the number of drilling rigs reduced to two.

Immediate priority for ongoing drilling will be to define the limit of the Colonna Zorzone deposit to the east of GDD098 and GDD100 and to the west of holes GDD135, GDD037 and GDD147 given that all of these holes contain significant mineralisation. It is also intended that additional in-fill drilling will be undertaken to the south of GDD145 down to the high-grade historical drilling on the 600 level.

The GDD135 intersection is entirely oxidised and appears to form a coherent zone of oxidised mineralisation encompassing the previously announced hole GDD118 (4.7m at 20.0% Zn+Pb) and recently drilled hole GDD147 (see Figure 2 below), which encountered approximately 15 metres of oxidised mineralisation of visually similar material to the intersection in GDD118.

This is the third area where significant quantities of zinc oxides (predominantly Hydrozincite and Smithsonite containing between 50% and 60% zinc) have been located within the Colonna Zorzone orebody. It is likely that this higher grade, completely oxidised material will bypass the Ore Sorters and be fed directly to the flotation plant, which will increase overall zinc oxide and lead oxide recovery.

In order to accommodate this scenario, a dedicated oxide ore pass to the proposed underground crushing facility has now been factored into the mine design.

Metallurgical testwork has continued to focus on increasing the zinc and lead recoveries from the 15% oxidised ore present within the Colonna Zorzone orebody. The results to date from this work, although not as impressive as the 95% recoveries for zinc achieved for the

sulphide ore, have been very encouraging and will be incorporated into the DFS once finalised.

As previously announced, the DFS will incorporate the proposed sale of three separate products; 1. A blend of lead oxide concentrate and lead sulphide concentrate; 2. A zinc oxide concentrate; and 3. A zinc sulphide concentrate.

Because of the small quantities of both lead and zinc oxides anticipated being produced from the Project, the possibility of blending a lower grade zinc oxide concentrate delivering higher recoveries with the zinc sulphide concentrate will also be investigated during discussions with off-take partners following completion of the DFS.

Energia’s Managing Director, Mr Kim Robinson, said the latest drilling continued to demonstrate the significant potential of the Gorno Zinc Project ahead of the completion of an updated resource estimate and Definitive Feasibility Study next month.

“We are now well and truly getting down to the business end of the Project, with work now underway on an upgraded Indicated Resource based on the drilling completed to date. This new resource, which is on track for completion by the end of March, will underpin the DFS due by the end of April,” he said.

“However, two rigs will continue operating focusing on areas where there is significant upside potential to the resource. One of these areas is where we have encountered significant thick zones of zinc oxide mineralisation, which we now know will play an important role in the future production profile of the Gorno Project.”

“Investors can look forward to strong news-flow over the coming weeks, with further assay results awaited ahead of the finalisation of the new resource estimate by early April.”

“That will, in turn, set the stage for the release of the DFS, which is progressing on schedule with the plant design component now in its final stages.”

“We are also experiencing a very high level of interest in the Gorno Project from potential off-take partners and financiers as well as from community stakeholders and both regional and provincial government authorities who are all working to bring forward the approval process. With the structural deficit in the zinc market now starting to bite and the outlook for zinc remaining extremely buoyant, we are very excited about the opportunity to bring this high-quality zinc project into production in the near future.”

mineralisation. Valley Type Lead Zinc deposits) it is broadly stratabound with some breccia
bodies and veining also occurring. It displays generally simple mineralogy of low
iron sphalerite, galena, pyrite, and minor silver. Gorno lies in a part of the Italian
Southern Alps named “Lombard Basin”, formed by a strong subsidence occurring
in the Permian-Triassic which allowed the subsequent accumulation of a thick
sedimentary pile. The sedimentary sequence is constrained laterally by the
Luganese Platform to the west and by the Atesina Platform to the east. The
lithotypes in the southern portion of the basin are predominantly Triassic in age.
The geological sequences of importance in relation to mineralisation, from oldest
to youngest are as follows:
o
Breno Formation: a back-reef limestone composed of light grey calcareous
beds, 10 to 170 m thick. The facies indicate a palaeogeographical evolution
from back reef to shelf environment, in low energy water to alternating
peri-tidal cycles.
o
Metalliferous Limestone:composed of dark grey to black limestone
deposited in stromatolitic tidal flats, with siliceous intercalations present in
the upper part. The dark colour suggests a stagnant anaerobic depositional
environment with bituminous beds generally present at the footwall of the
Metallifero. This formation represents a transitional phase between the
underlying shelf environment and the upper sequence typified by a peri-
continental and detrital sedimentation. Three tuffaceous levels are present
in the Metallifero stratigraphical column. The pyroclastic tuffs are
submarine volcanic phases which intervened during the deposition of the
limestones, and effectively represent a control for the mineralized horizons,
in that they are always found at the foot wall (Tuff 1) and at the hanging
wall (Tuff 2) of the productive mineralised horizons.
o
Val Sabbia Sandstone:present along the southern Lombard Basin border
and is composed of alternating tuffaceous sandstone and green and\or red
silt-mudstone. These were possibly derived from the erosion of continental
sediments present to the south. The thickness varies between 0 and 400
metres.
o
Gorno Formation: alternating thinly bedded, black limestone and
laminated marl deposited inprotected lagoon environment with a

thickness of 0-350 metres. A thin tongue, intercalated between the
Geology
(Continued)
Metalliferous Limestone and the Val Sabbia Sandstone, is often mineralised
and is referred to as the mineralised “black shales” of the Gorno deposits.
o
San Giovanni Bianco Formation: is composed of a thick alternation of marl,
sandstone, siltstone and mudstone which transitions at the top of the unit
to cellular limestone and evaporitic vuggy dolomite, estimated thickness of
150 metres.
 Structure in the basin is typified by E-W trending belts which can be subdivided in
five sectors:
o
Orobic Anticline,in the northern part, which includes Palaeozoic
successions;
o
Valtorta-Valcanale Line,oriented E-W and separating the Orobic Anticline
to the north from the Pb-Zn mineralised belt in the south. The line is
responsible for many of the allochthonous units;
o
Camuno Autochthonous,including the sedimentary cover, which is
covered in the central-western part by various overthrusts and outcrops
only in the east;
o
Para-autochthonous and allochthonous units,present over a large area to
the south of the Valtorta-Valcanale Line and formed by the double or triple
superimposition of the Triassic carbonate formations;
o
Fold and fold-fault zone,which constitutes the southern sector near the Po
plains and includes Jurassic-Cretaceous formations.
 Mineralisation in the Gorno district occurs within the Camuno Autochthonous
Zone, and the para-autochthonous, and allocthounous units. The geometry of
the mineralised bodies is mainly stratabound with common characteristics in the
majority of the Gorno deposits. The prevailing distribution trend is N-S and the
shape, represented by tabular “columns”, which can be longitudinally developed
for more than 2000 metres, with widths from 50 to 100 metres and thickness
between 3 and 20 metres.
