Mako Mine, Senegal – Exploration Update

July 10, 2018

Toro Gold (“Toro Gold” or the “Company”) is pleased to provide a further update on the results from the 15,000 metre core drilling programme currently in progress at its 90% owned Mako gold mine in Senegal. The programme is targeting mineralisation underneath the current open pit that has the potential to extend the life of mine.

Drilling highlights include:

  • 32m @ 3.4g/t Au from 239.5m in PWD371
  • 34m @ 2.8g/t Au from 209.5m in PWD377
  • 30m @ 2.9g/t Au from 199m in PWD380
  • 35m @ 2.3g/t Au from 214m in PWD370
  • 9m @ 3.1g/t Au from 220m in PWD369
  • 15m @2.2g/t Au from 226m in PWD374

The 15,000 metre, 60 hole core programme is now 50% complete and with 3 rigs turning the programme is scheduled for completion in early Q4 2018. To date 32 drill holes have been completed for 7,300 metres, and results received for twenty of those holes.

Howard Bills, Chief Exploration Officer, commented: 

“We continue to be encouraged by the results emerging from the deeper holes intersecting the Petowal mineralised zone immediately beneath the life of mine reserve pit.

 To date the mineralisation intersected throughout the programme is the down dip continuation of the main Petowal lode that forms the ore body. At South-West and Central Petowal the main mineralised zone is hosted by a felsic volcanic rock which is consistent with these latest drill results.  Further, as seen during previous drilling campaigns, higher grade sections of drill holes are typified by intense bleaching, abundant pyrite and in places a well-developed shear fabric.

 The programme will continue over the next few months with the aim of developing an updated mineral resource for the Mako mine towards the end of this year.  We look forward to updating you in due course with further results as they become available.”

Drill Programme Objectives

The main objective of the drilling programmes is to investigate the potential to extend the open pit life by further investigating the mineralised zone beneath the current final pit design.  In addition, some deeper drill holes will continue to investigate the potential for underground mining targets within a southwest plunging zone of mineralisation identified at SW Petowal and a steeply plunging zone at NE Petowal. Two areas of the Petowal ore body are being investigated:

  • Southwest and Central Petowal over a strike length of 460 metres (45 planned holes, 12,000 metres), and
  • Northeast Petowal over a strike length of 280 metres (10 planned holes, 3,000 metres).
 

Results to date

Of the 32 holes drilled to date the results for 20 holes (PWD362 to 381) have been received.  Table 1 below summarises these drilling and assay results.  Drilling at depth beneath the pit continues to confirm the Petowal geological model and mineralisation is being intersected where predicted by the block model.  Below are a series of cross sections that highlight mineralised intercepts and assay results in hole numbers PWD369 to PWD381.

Sample Preparation

Drill core is subjected to a series of logging and data recording procedures and then cut and sampled (1/2 core) over intervals of 1.5 metre intervals.  The ½ core samples are subjected to a standard industry practice sample preparation at Toro Gold’s sample preparation laboratory at Mako.  Samples are jaw crushed to a nominal top size of 2mm, 1kg is riffle split and milled (LM2) to 95% passing 75 microns and finally a 150g of pulp split is taken for assay.  Prepared samples are being routinely assayed at ALS Loughrea in Ireland by 50g Fire Assay with an ICP Finish.  Toro’s internal QA-QC procedures include introduction of 5% prepared Blanks, 5% pulp Duplicates and 5% CRM’s.  The sample preparation laboratory is audited on a 3 month basis by an independent consultant.
