Jubilee Reef Project


The Jubilee Reef Project comprises a contiguous group of licences covering approximately 116km2 that is located approximately 850km northwest of Dar es Salaam (see Figures 1 and 2) within the Lake Victoria Goldfield of northern Tanzania. This Archaean greenstone-granite terrain hosts several multimillion ounce gold deposits including Acacia Mining's Bulyanhulu deposit and AngloGold Ashanti's Geita deposit.

Mineral Resources

The total Inferred Mineral Resource for Jubilee Reef encompasses two deposits, Simba and Panapendesa, and is summarised below:

Note: As of November 2015.  Cut-off grade 0.7 g/t gold.  Inconsistencies in totals are due to rounding

The independent Mineral Resource estimates for the Jubilee Reef Project were prepared by Optiro Pty Ltd and reported and classified in accordance with the guidelines of the 2012 Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (the JORC Code; 2012). The Mineral Resources have been reported above a 0.7g/t gold cut-off grade to reflect current commodity prices and potential open pit mining and processing options. The Mineral Resources have not been constrained within an open pit.

Full details of the Resource estimate are provided in the ASX announcement titled "Liontown announces maiden 390,000oz Mineral resource for the Jubilee Reef Gold Project in Tanzania, East Africa" released on 30th November 2015 which is available on the Company website under the Investor Relations section.

Geology and Mineralization

The Jubilee Reef Project lies within a sequence of Archaean mafic volcanics, intermediate to felsic volcaniclastics, shales and banded iron formations (BIF) that form part of the Siga Hills Greenstone Belt within the Lake Victoria Goldfield. The Lake Victoria Goldfield hosts a number of world-class gold mining operations including the Bulyanhulu and Geita mines.

Simba deposit

The Simba deposit is located in the south-west corner of the Jubilee Reef Project (Figure 4) and is centred on the Masabi Syenite, an elliptical intrusion of syenite and diorite emplaced into the volcanic and volcaniclastic stratigraphy.

The intrusive complex comprises a series of felsic to intermediate intrusions forming a broadly east-west striking, rectangular body at least 1,600m long (east-west) by 700m wide. Gold mineralisation is hosted in massive but variably fractured and carbonate altered syenite, diorite, quartz diorite, and, along the southern contact, fine and coarse grained mafic volcanics and dolerites.

The mineralisation at the Simba deposit has been defined by 70 Reverse Circulation (RC) drill holes for a total of 8,735m, three diamond drill holes for a total of 982m and 26 rotary air blast (RAB) holes for a total of 758m.

Panapendesa deposit

The Panapendesa deposit is located some 1.8 km to the north-east of the Simba deposit and lies within a sequence of BIF, shale, and volcaniclastic sediments. The mineralisation at Panapendesa has been defined by 14 RC drill holes for a total of 1,937m and 16 RAB drill holes for a total of 677m.

Exploration Potential

Drill targets defined close to Simba and Panapendesa include

  • The gap between the 2 deposits where previous wide spaced, shallow drilling has not effectively tested beneath transported cover;
  • Possible parallel lodes at Simba which include individual intersections such as 15m @ 1.9g/t gold, 23m @ 2.9g/t gold and 17m @ 1.2g/t gold; and
  • The Koboko Trend which comprises a 2km soil anomaly coincident with a structurally complex BIF horizon.

Tembo Prospect

At the Temba Prospect, wide spaced trench sampling across a large complex soil anomaly has discovered a new zone of gold mineralisation at least 1.2km long. Highlights of trench sampling over these anomalies are indicated in Figure 7 below.

Acquisition and Ownership

In 2011 Liontown entered into a Joint Venture agreement with Currie Rose Resources Inc.. By September 2012, Liontown had earned an initial 51% by completing 14,000m drilling and, following Currie Rose's decision not to contribute to further exploration expenditure, subsequently increased its equity to 66%.

In April 2013, Liontown agreed to acquire the remaining 44% equity in the Project by issuing 12 million shares to Currie Rose.

Currie Rose will be entitled to a 2% net smelter royalty on future gold production from the Jubilee Reef Project; however, Liontown will have the option to purchase the royalty in the event that a Preliminary Economic Assessment is completed for a resource in excess of 250,000oz of gold (or gold equivalent).

Tenement Status

Prior to the passing of the recent amendments, The Tanzanian Mining Act (2010) provided companies with the right to apply for a Retention Licences (RL) over resources that were uneconomic at prevailing prices but that may be mineable within the foreseeable future.

In accordance with applicable law at the time, Liontown lodged a RL application over the Simba and Panapendesa gold resources in April 2017. The new legislation has repealed the right to apply for RLs going forward. However, it is currently unclear whether there will be any saving provision made to favourably deal with a RL application made prior to the enactment of the amendments. The Company is awaiting the release of the Regulations that will accompany the enacted changes to determine whether any such provision will be made.

Liontown retains nine other tenements which together with the RL application cover a combined area of approximately 120km2 in Tanzania.
