‘Heads or Tails’
ML20655 was pegged to incorporate a small deposit of tailings from previous mining that are now considered to be economic using current technological advancement to milling techniques.
The mining lease is located in close proximity to the tin mill, and the intention is to excavate the historical tailings and use them as feed for the mill. ML20655 is considered to be part of the pipeline of deposits MGT Minerals intends to develop.
MGT Minerals’ strategy is to create a pipeline of projects to provide feed for the tin processing plant at Mt Veteran (ML4349). Currently, MGT Minerals is working towards extraction of the Dalcouth and Summer Hill deposits (ML20547). Once the mill is running, MGTM will need to generate further feed, and the tailings at ML20655 is considered an easy target for extraction as the tailings are sitting on the surface.
The Mining Lease area also includes two other historic prospects: Queen and Queen Extended, which MGTM intends to explore to generate further mining targets.
The Heads or Tails tailings will be processed off-site, at the Mt Veteran tin mill. No infrastructure has been constructed on ML20655 or is currently planned to be, as material will be trucked to the Mt Veteran Mill (on a separate mining lease).
Extraction will be conducted using an excavator, as the tailings are currently sitting at the surface, so there will be no necessity to remove any overburden. The area of tailings to be extracted is ~5880 tonnes with an average grade of 0.42% Sn.
EMP16948
‘Nymbool’
EPM16948 “Nymbool” is located near the small township of Mount Garnet in north Queensland.
EPM16948 has known gold and tin mineralisation, which has been exploited in the past.
MGT Minerals considers the tenement to be prospective for bulk-tonnage, low-grade gold deposits, typically porphyry and intrusion-related mineralisation (Nymbool, Ambrose Gully), and hard rock and alluvial tin deposits (Smith’s Creek, Heads or Tails, White Dove).
There are a number of other targets that have been identified from the Queensland Government database and from aerial magnetic and radiometric surveys, which still need to be followed up.
In 2010 an RC drilling programme was conducted. A total of 22 RC holes were drilled.
Considering the limited modern hard rock exploration over EPM16948, the tenement is considered highly prospective for tin and gold mineralisation.
EPM25347
‘Nymbool Extended’
EPM25347 “Nymbool Extended”, is located near the small township of Mount Garnet in north Queensland.
MGT’s adjacent and contiguous EPM16948 has known gold and tin mineralisation, which has been exploited in the past. MGT Minerals considers EPM25347 “Nymbool Extended” to be prospective for bulk tonnage low-grade gold deposits (porphyry and intrusion-related mineralisation), and metasediment and granite-hosted tin mineralisation occurring in lodes, skarns and/or greisens.
EPM25690
‘Nymbool West’
EPM25690 “Nymbool West”, is located near the small township of Mount Garnet in north Queensland.
Potential exists for a number of styles of tin mineralisation within the application area including greisen mineralisation within the apical portions of intrusives, lode style tin mineralisation with fractures in the granites and skarn/lode mineralisation within favourable lithologies/structures in the Chillagoe Formation sediments.
There are a number of copper occurrences located within the tenement, while immediately adjacent to the tenement area there are numerous tin, copper and tungsten occurrences mainly within the granite intrusives.
A number of abandoned alluvial/eluvial tin workings lie alongside Black Creek. An iron occurrence with an associated airborne magnetic anomaly in the southern part of the application areas is suggestive of possible skarn development. The regional airborne magnetic data indicate a number of magnetic anomalies that may be related to either magnetic intrusives or possible magnetite skarn bodies.
EPM25716
‘Fuzzy Hill’
EPM25716 “Fuzzy Hill”, is located near the small township of Mount Garnet in north Queensland.
Potential exists for a number of styles of tin mineralisation within the application area including greisen mineralisation within the apical portions of intrusives, lode style tin mineralisation within fractures in both the granites and intruded Hodgkinson/Chillagoe Formations and skarn/lode mineralisation within favourable lithologies/structures in the Chillagoe Formation sediments.
There are a number of mineral occurrences in the easternmost part of the application area, localised in the Hodgkinson Formation sediments. These include the White Rose; a small abandoned tin mine, plus a number of small abandoned copper and/or lead mines.
The exploration plan is to thoroughly compile and evaluate prior exploration data and integrate this data with regional geological, geochemical and geophysical data sets to identify exploration targets with potential for tin mineralisation. Prospective targets will be evaluated by geological mapping, soil and rock chip geochemistry followed by drilling.
EPM25433
‘Nanyetta’
EPM25433 “Nanyetta” is located near the small township of Mount Garnet in northern Queensland.
Hard rock tin in the Mt Garnet region has been found in granite-hosted veins and greisen zones, but also within sediment-hosted fractures above intrusions. There have also been large-scale alluvial tin deposits in the creek systems draining from hard rock resources. Skarn mineralisation has been produced by alteration of carbonate sediments by intrusions.
The geology of EPM25433 is mostly comprised of Hodgkinson Formation metasediments, with a porphyritic microgranite intrusion outcropping in one area. MGT is particularly interested in understanding the relationship of mineralisation to the granite better.
From MGT’s exploration of Summer Hills (ML20547), it is clear that the Hodgkinson Formation sediments act as a competent host for fracture-related tin mineralisation, and existing mineralisation is expected to be related to an underlying intrusive, though this has not yet been intersected in drilling at any of the prospects so far. Exploration conducted over EPM25433 with its outcropping intrusive unit is expected to help MGT develop a better geological model for the mineralisation occurring within the mining lease, in turn allowing us to apply this knowledge to EPM25433.
