MORE HIGH GRADE MAGNETITE ENCOURNTERED AT YERBAS BUENAS

ASX Announcement 20th February 2020



Highlights

  • More thick and high grade intersections of magnetite encountered in two more holes assayed:


  • YB-025 86m @ 24.1% Fe (from 128 metres)
  • Including 18m @ 31.1% Fe (from 132 metres)
  • Including 20m @ 31.6% Fe (from 190 metres)


  • YB-026 129.5m @ 31.9% Fe (from 22.5 metres)
  • Including 22m @ 47.8% Fe (from 80 metres)
  • Including 15.9m @ 41.6% Fe (from 22.5 metres)



Freehill Mining Limited (ASX: FHS ‘Freehill’ or ‘the Company’) is pleased to announce that all drill core logging

and sample preparation to produce pulps at the ALS laboratory in Chile has now been completed from the

company’s recent diamond drilling program. Those remaining sample pulps will be dispatched shortly to ALS

Iron Ore Technical Centre laboratory in Perth for iron and magnetics analysis.


Assays results from two more holes – YB-025 and YB-026 – have today been published and again confirm that

more broad intercepts of high grade magnetite continue to be encountered across Yerbas Buenas. Freehill’s

technical team is very encouraged.


The majority of holes from this drill campaign were drilled at 60 degrees in an easterly direction with the

western-most hole on each drill line started well to the west of the structure as defined by geophysics so that

the deeper easterly margins of the structure could be defined. This has the effect that the upper portions of

some of those holes will penetrate through ground outside the structure and thus predictably contain barren

material.


Comments

Chief Executive Officer Peter Hinner said: “These are again excellent assay results with some outstanding thick,

high grade intersections. The scale of the project continues to grow with every new assay we report. The

magnetite we are encountering with the drill bit is readily and easily upgradeable to a high grade concentrate

that we can readily sell into the local market. Interest in Yerbas Buenas from third parties is growing and we

look forward to delivering shareholders with more good news on the project’s development and on more quality

assay results that will surely materialise.”

Significant Indication of Copper Mineralisation Identified in the Northern Area of Yerbas Buenas 

ASX Announcement 9 December 2019 


Highlights 

  • Geochemical survey shows strong copper mineralisation in northern area of Yerbas Buenas 
  • Study area contains two strong IP anomalies highlighted in previous Freehill exploration 
  • Grades of up to 0.9% Cu and 0.17 g/t Au returned (rockchip sample 525506) 
  • Drilling of the IP structures will target copper & gold mineralisation


Chile focused magnetite project development company and copper explorer Freehill Mining Limited (ASX:FHS; “Freehill” or “the Company”) is pleased to confirm the completion of a geochemical study covering the north eastern portion of the of the Company’s 100%-owned Yerbas Buenas(“YB”) project area which hosts two IP anomalies previously identified in 2018 and earlier in 2019 (ASX announcement 2 September 2019 (see Fig 1&3). 


This is the first time this northern area has been explored and the Company is pleased to confirm the presence of encouraging copper mineralisation in samples collected. The geochemical study covered an area of approximately 2 km2 and included 164 rockchip samples and 40 soil sediment samples (see Fig 4) which were analysed for copper, gold, cobalt, tellurium and iron.


Analysis of the geochemical results has highlighted a number of Cu, Au and Fe anomalies in the north-eastern portion of Freehill’s tenements (see Fig 6) and a diamond drill program targeting the northern IP anomaly as well as the anomalous Cu/Au mineralisation. The northern IP anomaly drilling will be carried out as part of Freehill’s current magnetite drilling program that is targeting a large magnetite structure contained on Freehill’s recently acquired southern tenement.


Geochemical Study Background 

Freehill contracted Tracking SPA (Tracking), a Chilean geological consulting firm that specialises in the exploration for Cu/Au mineralisation in Chile, to complete a geochemical and geological study of the area covering the two anomalies highlighted during Induced Polarisation (IP) geophysical programs carried out in 2018 and 2019 (see ASX releases 22 February 2019 & 17 April 2019 ).


The geophysical programs highlighted two IP anomalies, which are large structures with high chargeability, that start at near surface (northern anomaly) and between 100 and 150 metres below surface (southern anomaly). See Figure 1 for location of IP anomoly’s and current magnetite drill area. 


Figure 1 – Project area looking north and showing current area shown by red dotted area being drilled for magnetite and two locations to immediate north that are scheduled to be diamond drilled during December to test for copper mineralisation in two large Induced Polarisation anomalies 


The two structures appear to be east-west mineralised band or fault structures inside a larger north-south corridor along the eastern side of the property (see Figure 3) and both structures are open to the east and north. 


The two structures are consistent with the mineral distribution and tectonic controls found in the Chilean Iron Belt which has a known genetic and spatial link between IOA (iron oxide apatite) and IOCG (iron oxide copper gold) deposits. 


Geological surface mapping of the northern area shows several subvolcanic andesite bodies trending northwesterly in and associated with hornfels and quartz diorite bodies associated with magnetite mineralization on the district which are also associated with calc-sodic alteration of the host rock.


When plotted against the ground magnetics, the geochemical results (see Figure 6) and a northwest-southeast trend can be mapped in the geology, geochemistry and geophysics.

YERBAS BUENAS: ASSAYS CONFIRM HIGH GRADE

arrow-down-2 Created with Sketch.



ASSAYS CONFIRM MORE HIGH GRADE MAGNETITE AT YERBAS BUENAS

ASX Announcement 28th January 2020


Highlights

Freehill Mining Limited (ASX: FHS ‘Freehill’ or ‘the Company’) is pleased to announce that the diamond drilling

campaign carried out at the Company’s 100%-owned Yerbas Buenas project was successfully completed in late

December and early assays are indicating extremely encouraging iron results with more high grade magnetite

encountered.


Twenty holes were drilled using two diamond drill rigs with 4,805 metres drilled. Eighteen of the holes targeting

new magnetite mineralisation in the recently acquired Arenas XI tenement (see ASX announcement 2

September 2019).


To date, two of the 20 holes have been assayed and both holes have returned significant intersections of

magnetite over long intervals (see Table 2 below and refer highlights above).


Ore preparation of the diamond core is being carried out at Australian Laboratory Services (ALS) in Coquimbo,

Chile with the pulps sent to the ALS Iron Ore Technical Centre laboratory in Perth, Australia for analysis.


All samples will initially undergo XRF and Magnasat analyses with selected samples having Davis Tube analysis.

Due to the necessity of carrying out the analysis in Australia and the time for freighting samples, reporting all

assay results is expected to take several more weeks however the company will endeavour to report batches

of results as they become available.

Yerbas Buenas Drill Program Progressing Well 

ASX Announcement 19 November 2019 


  • 6 of 18 holes completed for 1,600 metres drilled – program ongoing along ~1.1km magnetite structure 
  • Remaining holes targeting extension of high grade YB6 structure hole YB016 (16m @ 61% Fe) 
  • Mineralisation extends deeper than initially indicated - third diamond rig mobilising to site to fasttrack program 
  • Assays expected late Dec – drill core produced to date showing a number of high grade intersections


19 November 2019: Chilean-focused magnetite and copper project exploration/development company Freehill Mining Limited (“Freehill” or “the company”, ASX: FHS) is pleased to report excellent progress of its current 18-hole diamond drill program at the flagship Yerbas Buenas (‘YB”) project in Chile.


Approximately 1,600 metres of drilling has been completed to date, being six of the planned 18 holes with drilling focused on the exceptionally high grade YB6 magnetite structure (refer Figure 2), which was discovered following the Company’s maiden drill program in late 2018.


The current drill program is targeting the YB6 structure which extends into the recently acquired and strategically important southern tenement Arenas XI (refer ASX announcement: 2 September 2019 and Figure 1).


Initial drilling shows that high grade mineralisation extends deeper than initially indicated by the 3D inversion model. A significant number of drill core intersections show the distinct black colouration typical of high grade magnetite and are supported by corresponding magnetic susceptibility readings (refer figures 3 and 4). Given these developments, the total number of metres drilled may be extended with this campaign. 


Drill core sample preparation is being carried out by an ALS laboratory in Coquimbo and samples will then be dispatched to the ALS Iron Ore Technical Centre in Perth for assaying with results expected in late December.


Drilling is ongoing with new targets outlined in Figure 5, overleaf. To ensure the program is completed prior to January, a third diamond drill rig will be mobilised next week.


Freehill’s Chief Executive Officer Peter Hinner commented: 

“To date, the planned drill program has progressed very well. The Company has not experienced any delays due to the social climate in Chile. We will shortly commission a third drill rig in the coming weeks and this clearly reflects the confidence we have in the project. 


“Initial indications of mineralisation at depth are encouraging and we look forward to exploring these sections further. YB’s Mineral Resource Estimate is expected to grow materially based on results from this drill program and future drilling. We look forward to reporting first assays and other exploration updates in the interim.”

DRILL PROGRAM

arrow-down-2 Created with Sketch.

4,500m Drill Program Underway at Yerbas Buenas 

ASX Announcement 24 October 2019 


Highlights

  • Diamond drilling has commenced at Freehill’s 100%-owned Yerbas Buenas magnetite project including new strategically important southern tenement Arenas XI 
  • Continuous 1.1km long magnetic structure where grades up to 61% Fe were intersected in our previous drilling campaign 
  • Geophysics modelling trebles the size of the YB6 magnetite structure 
  • Potentially high value copper targets being tested


Freehill Mining Limited (“Freehill” or “the Company”, ASX: FHS) is pleased to report that it has now commenced its next phase of magnetite drilling. Two diamond drill rigs are currently drilling on the project including the tenement (Arenas XI) acquired in August 2019 (reported ASX-FHS 2 September 2019) with the objective of completing the campaign by early December (see Figure 1).


Drilling in late 2018 included a high-grade hole (YB-016), containing 120m averaging 30% Fe starting near to surface, which was located near the southern edge of the project tenement in the YB-6 anomaly.


Freehill’s newly acquired tenement lies immediately to the south of YB-016 and a geophysical survey completed by Freehill confirms the YB-6 anomaly continues to the south and is entirely contained in the new tenement (see white boundary in Figure 1 below).


This provides a strategically important extension to the YB-6 structure and provides exceptional exploration continuity as the magnetic footprint of the YB-6 anomaly has been increased from 9.6 hectares to over 29 hectares.


The majority of this drilling program will be carried out on the significant extension of YB-6. 


Major features of the YB-6 structure extension are: 

  • Overburden is primarily mineralised sand cover and thus easy to strip (no blasting) 
  • Sits within predominantly gently sloping ground 
  • Simple pre-stripping process that can potentially generate revenue
