BASE RESOURCES LIMITED 
Kwale North Dune PFS Outcomes 
 
African mineral sands producer, Base Resources Limited (ASX & AIM: BSE) (Base 
Resources or the Company) has completed its Pre-Feasibility Study (Kwale North 
PFS) on the potential for the North Dune and Bumamani mineral deposits to 
extend the mine life at its 100% owned and operated mineral sands operations in 
Kwale County, Kenya (Kwale Operations).  The Kwale North PFS concluded that it 
is not currently viable to mine the entirety of these deposits primarily due to 
the combined low heavy mineral grade, high land acquisition costs and elevated 
slimes content and associated tailings disposal costs. 
 
The North Dune Mineral Resources are estimated at 194 million tonnes @ 1.5% 
heavy mineral and 37% slimes, and the Bumamani Mineral Resources are estimated 
at 5.9 million tonnes @ 1.9% heavy mineral and 21% slimes1.  The Kwale North 
PFS found the higher slimes content of the North Dune, relative to the 26% 
average slimes content of the Kwale South Dune currently being mined, would 
require a significant investment in additional tailings handling infrastructure 
and development of an innovative co-disposal methodology due to the lack of 
suitable tailings storage facility sites, materially increasing capital and 
operating costs. 
 
While the Kwale North PFS does not support mining of the entirety of the 
deposits, the Company has commenced an assessment of the potential feasibility 
for mining a higher-grade sub-set of the North Dune and Bumamani deposits, 
targeting low capital investment and the use of existing processing plant and 
tailings disposal capacity2.  Leveraging the work completed for the Kwale North 
PFS, the study phases for assessing this higher-grade option will be progressed 
on an accelerated timeline, with the results expected by mid-2021. 
 
[Note (1): The North Dune Mineral Resources estimate of 194 Mt comprises 119 Mt 
Measured, 73 Mt Indicated and 2 Mt Inferred Resources.  The Bumamani Mineral 
Resources estimate of 5.9 Mt comprises 3 Mt Measured, 2.6 Mt Indicated and 0.3 
Mt Inferred Resources.  Refer to Base Resources' market announcement "Updated 
Kwale North Dune and maiden Bumamani Mineral Resources estimates" released on
