Mr. Adam Lundin reports:
VANCOUVER, BRITISH COLUMBIA--(Marketwired - May 17, 2017) - Filo Mining Corporation (TSX VENTURE:FIL)(NASDAQ OMX:FIL) ("Filo Mining" or the "Company") is pleased to provide a summary of the overall results of the 2016 / 2017 program at the Filo del Sol project, including the results of the final 14 holes from the recently completed 41 hole drill program, and an outline of the next steps for the project. The results released today continue to confirm and define the shallow gold oxide and high-grade copper and silver zones in the Filo del Sol deposit, and demonstrate the potential for significant new zones of shallow oxide gold and copper mineralization one kilometre south of the current resource at the Filo South zone.
A total of 8,616 metres was drilled in 41 holes during the exploration program which was completed on March 28th. The results presented here are from two areas: the Filo del Sol deposit and the Filo South zone. Intersections from the Filo del Sol deposit are from infill holes contained within the current Mineral Resource estimate, while those from the Filo South zone are entirely outside the current resource. Unless otherwise stated the results presented here are from the final 14 holes of the program. For further information on earlier holes the reader is referred to News Releases dated February 15, 2017 and April 10, 2017. Detailed drilling results and a drill hole location map are included at the end of this release.
Filo Mining CEO Wojtek Wodzicki commented, "We had a very successful exploration season at Filo del Sol. We believe that we have enhanced the existing resource and have made a significant new discovery in the Filo South area. Our drilling has demonstrated that we have an important oxide gold zone in the upper part of the current resource. The infill holes into the copper and silver zones have highlighted the impressive grades and thicknesses present in the high-grade portions of these zones. Today's results set us up for an eventful second half of the year. In the coming months we will incorporate this season's drill results into an updated resource estimate, and receive results from our phase 2 metallurgical program which will provide the information to begin engineering studies during the third quarter."
Filo del Sol Deposit Infill Drilling
Successful Infill Program: The infill drill program was very successful and is expected to convert a portion of the current Inferred Resource to Indicated. Infill drilling continued to confirm the deposit geometry, intersecting three discreet zones of mineralization. From top to bottom these are a gold oxide zone, a high grade copper oxide zone and a high grade silver zone. These three zones are underlain by primary sulphide mineralization containing both copper and gold which remains open at depth. This year's drilling focused on definition of the upper three zones and most holes were terminated at the contact with the underlying sulphide mineralization. Hole VRC100 summarized below is a good example of a hole which intersected all three zones.
- Gold Oxide Zone: 52 metres @ 0.51 g/t Au
- Copper Oxide Zone: 60 metres @ 1.01% Cu and 0.24 g/t Au,
- High grade Silver Zone: 34 metres @ 138.1 g/t Ag, including 16m @ 227.5 g/t Ag.
Expanded gold oxide zone: The drill program expanded and further defined the gold oxide zone, with 11 new intersections. This year's drilling has increased the dimensions of this zone to approximately 700 metres north-south by 350 metres east-west. The intercepts from this year include some of the best gold mineralization drilled at Filo del Sol to date and it is anticipated that this zone will form an important part of the updated resource estimate. Notable new results announced today include:
- VRC132: 42 metres at 1.04 g/t gold;
- VRC126: 20 metres at 0.82 g/t gold;
Confirmed high grade copper oxide zone: Beneath the gold oxide zone is a discreet, high-grade copper oxide zone with associated gold. The copper zone has a very sharp upper contact, often going from <0.10% Cu to >1.00% Cu within less than a metre. The drill holes reported today are infill holes that are expected to convert a portion of the Inferred Resource to Indicated. Notable new results announced today include:
- VRC100: 60 metres @ 1.01% Cu, including 26 metres @ 1.56% Cu;
- VRC123: 33 metres @ 0.50% Cu;
- VRC125: 71 metres @ 2.06% Cu, including 30 metres @ 3.03% Cu;
- VRC132: 28 metres @ 0.91% Cu;
Confirmed high grade silver zone: A flat-lying, stratiform silver-rich zone underlies the copper oxide zone in most areas of the deposit. This zone has been intersected over a north-south distance of 1.5 kilometres and an east-west distance of 400 metres. Three of the holes announced today intersected this zone within the current resource and are expected to covert a portion of the Inferred Resource to Indicated.
- VRC100: 34 metres @ 138.1 g/t Ag, including 16 metres @ 227.5 g/t Ag);
- VRC126: 20 metres @ 105.7 g/t Ag, including 6 metres @ 208.0 g/t Ag);
- VRC132: 34 metres @ 285.1 g/t Ag, including 16 metres @ 565.1 g/t Ag).
Holes VRC100 and VRC126 were terminated in high-grade silver mineralization due to drilling difficulties.
New Discovery at the Filo South Area
Drilling in the Filo South area followed up on historic drill holes and more recent surface trenches which intersected significant copper and gold mineralization but were spaced too far apart to allow for correlation between holes or an estimation of the size of the zones. Following this year's drilling Filo South is characterized by a variety of mineralized intersections over an area of 1,000 metres north-south by at least 500 metres east-west. Mineralization appears to be related to the oxidized upper portion of a significant porphyry system and is distinct from the high-sulphidation epithermal mineralization at the Filo del Sol deposit proper. Following this season's drill program, mineralization in Filo South has tentatively been subdivided into three zones:
Filo South gold zone: Drilling has started to outline an area of oxide gold mineralization extending from the surface to an average depth of approximately 100 metres. Drill holes VRC133 and VRC134 (see below), stepped out from historic hole RCVI16 (116m @ 0.52 g/t Au) and previously announced VRC109 (94m @ 0.56 g/t Au) and intersected broad zones of similar grade oxidized gold mineralization:
- VRC133 56 metres @ 0.53 g/t Au from surface, including 0.88 g/t Au upper 16 metres.
- VRC134 100 metres @ 0.57 g/t Au from 6 metres, including 28 metres @ 0.80 g/t
Together with RCVI16 and VRC109, these holes outline a continuous, shallow oxide gold zone across approximately 400 metres in a northeast-southwest direction (see attached section). To the northwest, the nearest hole, located 200 metres away, is RCVI12 (18m @ 1.28 g/t Au starting at 4 metres). Additional drilling will be needed to fully define the size and grade of this new zone.
Filo SW copper zone: Previously released drill holes VRC110, VRC111, VRC112, VRC113 and VRC119 followed up a shallow copper oxide zone originally drilled in hole RCVI02 (40m @ 1.19% Cu). These drill holes all intersected similar widths and grade, and are starting to outline a zone with a strike length of at least 320 metres and possibly up to 570 metres assuming continuity with a previous hole (VRC008 - 38m @ 0.61% Cu) which is along trend to the southeast. These drill holes were announced in a News Release dated April 10, 2017 and are included here as part of the summary of the results of the whole program.
Filo Northeast copper-gold zone: Hole VRC103 (see April 10, 2017 News Release) discovered a new area of copper mineralization which was followed up by hole VRC128, collared 150 metres to the northwest. VRC128 was successful in intersecting the copper zone, with 16 metres @ 0.87% Cu and 0.32 g/t Au. It is not yet clear how the mineralization in this area relates to the other zones.
Mineralization at Filo South is not currently included in the current Filo del Sol resource estimate, and it is anticipated that the upcoming resource estimate will establish an initial resource for this high-priority area. The newly discovered zones in the Filo South Area all remain open for expansion and will require further drilling to fully delineate them.
- Resource Update: We expect to complete an updated resource estimate including all of this year's drilling by the third quarter of 2017.
- Metallurgical test work: Approximately 2.8 tonnes of material from the oxide gold and copper zones were collected and submitted to SGS Lakefield laboratory for column leach testing. Additional material from drill samples was submitted for test work on the silver zone. Results are expected early in the third quarter of 2017.
- Internal Scoping Study: Once the resource update and metallurgical test work is complete, we expect to do an internal scoping study that will analyze various development options. The work is expected to be completed during the third quarter allowing a decision on whether to proceed to a Preliminary Economic Assessment early in the fourth quarter of 2017.
