Mako Mine, Senegal – Exploration Update

May 22, 2018

Toro Gold (“Toro Gold” or the “Company”), a gold producer, developer and explorer with assets in
West Africa, is pleased to announce the first results from a 15,000 metre core drilling programme at
its 90% owned Mako gold mine in Senegal.

Highlights include:

  • 31m @ 3.4g/t Au from 196m in PWD 367;
  • 42m @ 2.2g/t Au from 244m in PWD365;
  • 24m @ 2.3g/t Au from 233m in PWD366;
  • 15m @ 2.3g/t Au from 189m in PWD364; and,
  • 37m @ 1.7g/t Au from 188m in PWD368.

The programme commenced in early February 2018 and will comprise 15,000 metres of core drilling for up to 60 holes.  The programme is scheduled for completion in early Q4 2018 when an update of the Mineral Resource Estimate will be undertaken for use in a mine planning exercise before the end of 2018.  To date 18 drill holes have been completed for 3,700 metres.

Howard Bills, Chief Exploration Officer, commented:

“We are really encouraged by this first set of drill results after a two-year pause in exploration drilling at Petowal while we focused on construction of the Mako mine.  The potential for further Resource growth has been well understood by the Company and these first results support that confidence in the ability to add more ounces to the Mako mine inventory and ultimately the Reserve base.  The Petowal geological model is well understood and we are seeing typical Petowal style mineralisation in the drill holes intersection at depth beneath the pit.  The programme is now well underway and with three rigs turning we expect to have a steady flow of drill results over the coming months. We look forward to providing regular drilling updates throughout the programme.”

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 final pit design on a 40m * 40m drill spacing.  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, 3000 metres).

Results to date

Of the 18 holes drilled to date the results for 7 holes (PWD362 to 368) have been received, their summarised drilling and assay results are provided in the table, below.  Drilling at depth beneath the pit continues to confirm the Petowal geological model and mineralisation is being intersected where predicted by the geological interpretation.  Maps below contain a series of cross sections that highlight mineralised intercepts and assay results in hole numbers PWD363 to PWD368.

Sample Preparation and Analysis

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.  The ½ core samples are subjected to a standard industry practice sample preparation process at Toro Gold’s 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 at Mako is audited on a 3-month basis by an independent consultant.
