LABORATORY CONFIRMS STUNNING ALUMINA GRADES

ASX Release 19th May 2020


HIGHLIGHTS
Laboratory confirms stunning Conglomerate Alumina grades for both extensions

  • All samples from the Bouba extensions have now been XRF analysed for Alumina in the laboratory

  • Bouba North & South extensions confirmed as very high-grade Conglomerate Bauxite

  • The resource has grown from the primary resource defined in the first set of assays, but the resource does not appear to have altered in grade or quality from those primary works

  • These stunning results add significant scale to the very high-grade Conglomerate Bauxite and the entire project area

  • Digestion test work will be undertaken in the coming weeks to determine the Silica classification, it can be assumed that the Digestion test results will be similar to the test results from the Boba Plateau

  • Company is on track to release its inaugural JORC compliant resource statement before mid-year


Lindian Resources Limited (“Lindian” or “Company”) (ASX Code: LIN) is pleased to provide an update on its XRF laboratory results for the Alumina grade for the extensions to the Bouba Conglomerate Bauxite Plateau at the Gaoual Bauxite Project in Guinea (“Project”).


All samples from the drilling program that was undertaken to test the Bouba North and South extensions have undergone XRF analysis in the laboratory to determine the Alumina grade.


The two areas that were drilled and have been analysed are:

Bouba North - An approximately 1km northern extension to the Bouba Plateau at a lower elevation
Bouba South - An area defined as Bouba South on the other southern side of the Tomine River to the south of the Bouba Plateau


The Company has completed all drilling within the currently identified northern and southern extensions of the Bouba Conglomerate Bauxite Plateau with, absolutely stunning Alumina grades consistently continuing. The resource has grown from the primary resource defined in the first set of assays, but the resource does not appear to have altered in grade or quality from those primary works.

Tables 1 and 2 below show a selection of holes from each area and their average Alumina grade based on the laboratory XRF results.

ASSAYING CONFIRMS VERY HIGH GRADE CONGLOMERATE BAUXITE

ASX Release 4th May 2020


HIGHLIGHTS

  • Laboratory XRF analyses confirms the very high-grade nature of the Conglomerate Bauxite as the Company continues to build scale

  • Digestion test work confirms the gibbsite dominant nature of the Conglomerate Bauxite located within the Bouba Plateau

  • Total Available Alumina (TAA) for all Bouba Plateau samples (average grade 56%) in low temperature digestion averaged 80% and in high temperature digest 92% TAA is achieved (TAA value in excess of 51% Al2O3)

  • Reactive Silica (RSi) contents are ~50% of the primary Silica content within low temperature digestion tests (average 6.2% SiO2, with low temperature digestion yielding only 3.0% RSi)

  • The remaining samples from the drill program have been prepared and are in transit to Perth for analysis in the coming weeks


Lindian Resources Limited (ASX Code: LIN) is pleased to provide an update on the assaying and digestion test work on the initial drill samples derived from the Bouba Conglomerate Bauxite Plateau and Mamaya Plateau at the Gaoual Bauxite Project in Guinea (“Project”).


Results from the Bureau Veritas (Perth) laboratory have been forwarded to Lindian, representing the drill samples from the initial drill program. The samples are as per below:


  • 655 samples from the Bouba plateau were analysed by XRF, with a selection of 58 further tested using digestion techniques at both high and low temperature digestions.
  • 295 samples from the Mamaya plateau were analysed by XRF, with a selection of 18 further tested using digestion techniques at both high and low temperature digestions


Table 1 below shows a range of grades that were confirmed by the XRF within the high grade Bouba Conglomerate Bauxite Plateau, and the “in situ” Mamaya Plateau.



The Conglomerate Bauxite has been logged from surface to the basal unconformable contact across the full extent of both areas of the Bouba Plateau as defined by the Geologists during the initial and follow up discoveries. The grades for all defined conglomerate bauxite remain universally high through the Bouba Plateau with no geochemical zonation seen either down profile or within the Plateau North to south or East to West.


Aspects of the Bouba Conglomerate Bauxite that can be derived from the XRF data is that there is a very low level of Fe2O3 present within all of the conglomerate bauxite samples, and through stoichiometric balance noting that the Boehmite (mono aluminum oxide hydrate) levels can range from low 2-3% to moderate levels of ~15% of the aluminum oxide hydrates present. It is also note that the SiO2 levels are also variable throughout the profiles, with the base of the conglomerate being an unconformable contact with the SiO2 rich sandstone basement rocks of the region.


Digestion Test Work

A total of 76 samples were selected for low temperature and high temperature test work from the primary 950 samples analyzed. Fifty-eight samples (58) representing seven (7) drill holes, were from within the Bouba Conglomerate Bauxite Plateau and eighteen samples (18) representing two (2) drill holes were from the Mamaya Plateau. 


The samples were “mini-digests” completed by the Bureau Veritas (Perth) testing facilities – all reported values were determined by ICP analysis. Summary data of these test results is presented in Tables 2 and 3.




The digestion test work confirmed that the Bouba Conglomerate Bauxite Plateau is high grade and predominantly Gibbsite rich bauxite deposit. Recoveries in low temperature digestions were not affected by the RSi content (which formed approximately 50% of the total SiO2) but were determined to be affected by the presence of Boehmite (estimated stoichiometrically from the primary XRF analysis). Recoveries in high grade digestions were universally high for TAA, and this recovery was not affected by the sympathetic increase in the RSi.


Further Drilling Sample Analysis

The Company has completed all drilling requirements within the northern and southern extensions of the Bouba Conglomerate Bauxite Plateau, with a further 214 samples from these drilled extensions in transit to the Bureau Veritas laboratory (Perth) for XRF analysis. These samples are expected to contain similar grades to the high grades encountered from the primary program of works being reported here.

At the completion of the remaining XRF and Digestion assaying the analyses will be used in the development of a fully compliant JORC resource.


Independent Geological Expert Mark Gifford Commented “Assaying and digestion test work results continue to show the impressive high-grade nature of the Bouba Conglomerate Bauxite Plateau. With the capacity to determine the areas of low boehmite presence within the resource, an extremely valuable resource with an exceptionally high TAA content could be attained within the resource tonnage, making the Bouba Conglomerate Bauxite a valuable addition to the Guinea resource landscape.”


Managing Director Shannon Green Commented “It is a fantastic milestone to finally be able to communicate these terrific results following the receival of both the XRF and digestion test work for the initial drilling program and most exciting is that the results show the truly world class nature and quality of this incredible and unique resource.”

  • Laboratory analytical test work currently being undertaken in Perth,

    Western Australia


OVERVIEW

The Gaoual Bauxite Project is in north western Guinea within the Boke Bauxite Belt. It is situated south of the township of Gaoual in the northern portion of the Cogon-Tomine interfluve, about 65 km northeast of Sangaredi. The company is currently acquiring up to 75% of the Gaoual Bauxite Project. The Project potentially holds a significant Conglomerate Bauxite resource. Conglomerate - Bauxite is the primary ore of the initial discovery of the Sangaredi Bauxite deposit mined by Compagnie des Bauxites de Guinée (CBG) which is known as a significant high-grade Bauxite producer.


Conglomerate - Bauxite is considered far superior to common bauxite in Guinea (and elsewhere) due to its high grade and chemical properties that lend themselves to more efficient refining.


The unique nature of the Conglomerate-Bauxite implies that this ore may have some similar physical and depositional characteristics to the primary discovery of the Sangaredi Deposit mined initially by CBG. These ores were unusual due to the very deep profiles (often in excess of 30m), continuous high-grade ores (>50% Al2O3) from the top to base of the profile and with very low deleterious element contents (Reactive Silica /C)


Figure 1 below is the conglomerate Bauxite Plateaux (Bouba) looking north

page2image1155757792

DRILLING PROGRAM

The initial drilling program was completed during the quarter at the Bouba and Mamaya Plateaux. Both Plateaux have significant bauxite present, with the very high grade Bouba Plateau having consistent very high-grade Conglomerate Bauxite and the Mamaya Plateau having significant in-situ bauxite being defined across the total width and length of the plateau, with the depth of Bauxite in areas exceeding 15m.


Indications from the preliminary logging and on-site assaying confirmed the very high-grade nature of the Bouba Conglomerate Bauxite, with the very high-grade ore through the total Conglomerate Bauxite profile.

Figure 2 below shows the very high-grade Conglomerate Bauxite pebbles being recovered during the drilling process at the Bouba Plateaux.


page3image1154023264

Figure 2: Drilling Conglomerate Bauxite Bouba Plateaux


DRILLING PROGRAM - BOUBA PLATEAU

The Bouba Plateau was the primary exploration target for the initial drilling program. Significant outcropping high-grade bauxite was tested across the plateau’s surface and all drilling within the mapped ore zone intercepted high-grade Conglomerate Bauxite. Drilling was completed at 300m centres ensuring the potential resultant resource can be JORC classified to a very high level of confidence.

Bauxite mineralisation was recorded from surface across the total plateau, with depths of 10-12m of bauxite on the eastern margin, thinning to 5-7m on the western margin. 


The mineralised area has been accurately geologically mapped by the geological staff.

Initial onsite assaying of the samples was completed by portable XRF with typical grades encountered by the drilling as below:


  • 12m @ 61.3% Al2O3 5.3% SiO2 4.9% Fe2O3

  • 10m @ 62.7% Al2O3 4.5% SiO2 8.1% Fe2O3

  • 8m @ 62.3% Al2O3 8.1% SiO2 4.8 %Fe2O3

  • 12m @ 57.5% Al2O3 6.7% SiO2 7.2% Fe2O3


It is apparent that the surface high grades of the conglomerate bauxite are replicated to depth, with every metre within the bauxite zone defined by geological logging having very high-grade bauxite ore without break to the unconformable contact with the basal sandstone of the region. There is no indication of increasing iron content towards the basal zone as seen in most local in situ bauxites, and there is no break in the conglomerate lithology of the bauxite intercepted by drilling.

The silica content of the Bouba Plateau is slightly higher than seen in the surrounding in-situ bauxites of the region and this could be due to an aeolian fraction that has incorporated itself into the conglomerate that can trap these sands, during and post deposition.


It should be noted that the silica content could predominantly be present as quartz (as noted in logging), and as such the reactive silica (RSi) could still be very low due to the mineralogy of the silica rich minerals, ensuring a high Total Available Alumina (TAA) content for this rare Conglomerate Bauxite.

Very High-Grade Conglomerate Bauxite Extensions Confirmed

ASX Announcement 30th March 2020


HIGHLIGHTS
Drilling confirms Significant extensions to the very high-grade Conglomerate Bauxite as the Company continues to build scale

  • An approximately 1km northern extension to the very high grade Bouba Plateau confirmed to be Conglomerate Bauxite

  • Bouba South confirmed to be Conglomerate Bauxite, an area estimated be approximately 0.5km by 2.5km, located approximately 1.5km to the south east of Bouba plateau on the southern side of the Tomine River

  • All samples from the initial phase 1 drilling program have now been received by the analytical laboratory


Lindian Resources Limited (“Lindian” or “Company”) is pleased to provide an update on its follow up drilling program targeting the extensions to the Bouba Conglomerate Bauxite Plateau at the Gaoual Bauxite Project in Guinea (“Project”).


Ongoing geological field works identified two (2) new significant areas of the very high-grade Conglomerate Bauxite as follows:


  • An approximately 1km northern extension to the Bouba Plateau at a lower elevation
  • An area defined as Bouba South on the other southern side of the Tomine River to the south of the Bouba Plateau

Figure 1 below shows the two (2) new significant areas of Conglomerate Bauxite relative to the very high grade Bouba Conglomerate Bauxite Plateau.


page1image1349789600

Bouba Plateau Northern Extension


The Company has completed its drilling program on these two (2) new areas which, has confirmed from the preliminary logging by the Geologists to be Conglomerate Bauxite and it is expected to be of a very high-grade nature consistent with Bouba Plateau preliminary assays.


The Conglomerate Bauxite has been logged from surface to the basal unconformable contact across the full extent of both areas as defined by the Geologists during the initial discovery.


The two new areas of Conglomerate Bauxite are set in lower elevations as compared to the Bouba Plateau and are comprised of rounded spherical to elongated pebbles of Gibsittic bauxite cemented by the Bauxite matrix. The textural fabric suggests that they are both of sedimentary origin forming Conglomerate Bauxite. Drilling of both areas confirmed that the Conglomerate Bauxite is underlaid by either sandstones or iron rich laterites.


The Geology of the northern extension of Bouba Plateau is very similar to the Bouba Conglomerate Bauxite. The area is comprised of Bauxite mineralization with an average thickness of approximately 4m from surface with depths of 7m from surface being intercepted.


Bouba South an area located approximately 1.5km to the south east of Bouba plateau on the southern side of the Tomine River which, is very shallow in this area and appears to be comprised of highly re-bauxitized Conglomerate Bauxite. The geology suggests a very high-grade bauxite mineralization with an average thickness of approximately 5m from surface with depths up to 9m from surface being intercepted.


It is important to note that consistent with the Bouba Plateau there is absolutely no cover in either area, the Conglomerate Bauxite is from absolute surface of every hole drilled.

All samples will be prepared for transport to the preparation laboratory as quickly as possible.

  • Lindian Resources (ASX: LIN) shareholders vote to proceed with the transaction to earn up to 75% of the Gaoual Conglomerate Bauxite Project in Guinea
  • Fast track drilling program for the Gaoual Conglomerate Bauxite Project to commence December 2019
  • Potential world class Conglomerate Bauxite deposit

“Guinea is to Bauxite as the Pilbara is to Iron Ore”

When you think of iron ore, you naturally think of the Pilbara. When you think of bauxite, the raw ingredient for the manufacturing of aluminium, you need to think of Guinea in West Africa. Guinea is home to approximately a third of the world’s reserves of bauxite and is rapidly expanding its bauxite exports, predominantly to China.

 The government of Guinea has designated 2020 to be the “Year of Investment” and the country expects a large number of energy and resource deals to be signed over the next year many involving foreign investment.

 With this backdrop, Lindian Resources offers a compelling investment opportunity given it is sitting on what could be one of Guinea’s most promising bauxite projects.

                              
                             

Figure 1 The Compelling Opportunity

                                                  
                                                    At the recent Annual General Meeting (AGM), Lindian Resources’ Shareholders voted overwhelmingly in favour of approving the acquisition of the Gaoual Project. As a result, Lindian Resources now has the legal right to earn up to 75% of the potentially world class Gaoual Conglomerate Bauxite Project in Guinea. The Project is characterised by very high-grade low contaminant Conglomerate Bauxite.

 When it comes to bigger companies, Guinea is already home to one of the world’s largest bauxite export operations, Compagnie des Bauxites de Guinée (CBG), a joint venture between Alcoa, Rio Tinto & Dadco (Halco) and the government of Guinea.  Lindian’s Gaoual Conglomerate Bauxite Project shares similar geological characteristics with the massive CBG Bauxite operation. The operation commenced in the early 70’s mining the very high grade Sangaredi Conglomerate Bauxite which is now depleted. However, the operation continues today exporting its massive Typical Insitu Bauxite resources. The Gaoual Conglomerate Bauxite Project area is located approximately 65 km as the crow flies from the CBG operations which is connected by railway to the Kamsar Port.

Lindian Resources’ (ASX: LIN) Managing Director Shannon Green knows Guinea well and has said, “In my 8 years developing mining projects in West Africa, I’ve never seen a better opportunity than our Gaoual Bauxite project in Guinea. Lindian believes it has discovered Conglomerate-style Bauxite at Gaoual which would make it globally unique due to its high grade and quality”.

Lindian Resources Fast Tracks Drilling Program

Lindian Resources recently announced the bringing forward of its planned drilling program and the appointment of Sahara Natural Resources to complete its fast track drilling program at its Gaoual Bauxite Project in Guinea.

The fast track drilling program is scheduled to commence next month and will comprise 34 auger holes drilled at approximately 600 metre spacings. Bouba Plateau is the primary Conglomerate Bauxite target within the Gaoual Project.

Lindian Managing Director Shannon Green said, "We are very pleased to be partnering with Sahara who have an excellent international reputation and strong local capabilities to deliver. In line with our recently fast-tracked timeline, permitting at Gaoual is on-track to be completed ahead of drill equipment mobilisation in late November.”

Initial indicative results from the fast track drilling program are expected to be received in December 2019. With the first hole set to be drilled in December, we are confident of having initial results from this program by calendar year end, I look forward to reporting further updates as we move closer towards commencement of drilling at Gaoual,".
