Skyharbour Resources Ltd. (TSX-V:SYH) (OTCQB:SYHBF) (Frankfurt:SC1P) (the “Company”) is pleased to announce the results from its 2018 winter/spring diamond drilling program at its flagship 35,705 hectare Moore Uranium Project, located approx.15 kilometres east of Denison Mine’s Wheeler River project and near regional infrastructure on the southeast side of the Athabasca Basin, Saskatchewan. Drillhole ML18-08 intersected high grade uranium mineralization within the Main Maverick Zone consisting of 5.39% U3O8 over 1.0 metre within an interval containing 2.07% U3O8 over 3.5 metres. This mineralization occurs at the unconformity from 265.8 to 269.3 metres downhole. Also of note is hole ML18-09 which intersected uranium mineralization at the unconformity in the Maverick East Zone, a new high grade lens discovered by Skyharbour last year. This hole returned a grade equivalent of 3.07% U3O8 over 1.8 metres from an interval containing a grade equivalent of 1.01% U3O8 over 6.3 metres.


  • Hole ML 18-08 drilled on the Main Maverick Zone returned an unconformity-hosted intercept of 2.07% U3O8 over 3.5 metres from 265.8 to 269.3 metres downhole, including 5.39% U3O8 over 1.0 metre.
  • Hole ML18-09 drilled at the Maverick East Zone returned a grade equivalent of 1.01% U3O8 over 6.3 metres from 275.4 to 281.7 metres downhole at the unconformity, including an interval of 3.07% U3O8 over 1.8 metres.
  • Three of the four holes drilled at the Maverick corridor in this program returned high grade uranium mineralization and successfully expanded the known high grade zones.
  • Only 2 kilometres of the total 4 kilometre long Maverick corridor have been systematically drill tested leaving robust discovery potential along strike as well as at depth in the underlying basement rocks which have seen limited drill testing historically.
  • Regional diamond drill hole ML18-03 tested the Venice target 8 km northeast of the Main Maverick Zone, and intersected uranium mineralization in graphitic pelites that occur just below the unconformity in the basement rock at 279 metres downhole.
  • Given the success of the 2018 winter/spring drilling program at Moore, planning is currently underway for a minimum 3,000 metre summer diamond drilling program to commence in August; additional news and details are forthcoming.

Jordan Trimble, President and CEO of Skyharbour Resources, states: “The recently completed winter/spring drill program at the Moore Project has expanded the known high grade zones at the Maverick corridor by intersecting relatively shallow uranium mineralization at the unconformity. Furthermore, new regional discoveries were made at the Venice target. We will be commencing a summer drill program to follow up on these results and test more extensively new targets in the underlying basement rock at the Maverick corridor. The known high grade, unconformity-hosted uranium mineralization at the Maverick corridor was deposited there through feeder zones in the basement rock, the discovery of which will be a top priority in this upcoming program given other recent basement hosted discoveries including NexGen’s Arrow Deposit, Fission’s Triple R Deposit and Denison’s Gryphon Deposit. Skyharbour is well positioned with strong discovery potential and ample upcoming news flow to benefit from an impending uranium market recovery. In the last few months we have witnessed increasing uranium prices and improving sentiment amid recent news including additional supply cuts announced from Kazakhstan, accelerating Japanese nuclear reactor restarts, and a new uranium fund based in London buying over eight million pounds of uranium from KazAtomProm.”

Winter 2018 Drill Program Summary and Upcoming Summer 2018 Drill Program Plans:

The recently completed winter/spring diamond drilling program totaled 3,399 metres in 9 holes which were drilled to a depth of between 330 and 525 metres. Five of the nine holes were drilled on regional grids testing geophysical targets and as a follow up to previous drilling, while the remaining four holes were drilled on the high grade Maverick structural corridor.

Skyharbour is planning for a minimum 3,000 metre 2018 summer diamond drilling program slated to commence in August. The majority of this drilling will test the high grade Maverick corridor both above the unconformity and below it in the basement rocks. Skyharbour’s technical team has recently reinterpreted historical drill results and has identified new high-priority drill targets in the basement rock at the Maverick corridor below the known high grade mineralization. The underlying basement feeder zones for the unconformity-hosted high grade uranium at the Maverick corridor have yet to be discovered and have seen limited drill testing.

Drilling at the Maverick Corridor and the Venice Zone:

Four holes in this program tested the high grade Maverick Main Zone and Maverick East Zone. The best results were from ML18-08 which tested the Maverick Main Zone and ML 18-09 which tested the Maverick East Zone. Hole ML18-08 intersected 2.07% U3O8 over 3.5 metres at the unconformity.

The most encouraging results from the drilling on the regional grids were obtained from ML18-03 which tested targets on the Venice grid. This hole intersected a strongly altered and structurally disrupted basal sandstone column and basement rocks. This hole returned anomalous pathfinder elements as well as a 0.5 metre interval containing 0.154% U3O8 in graphitic pelites just below the unconformity in the basement rock. The Venice target is a high-priority regional target going forward given this recent discovery.  

Uranium Market Commentary and Update:

The uranium market has recently shown notable signs of recovery with increasing uranium prices and improving sentiment, and this recovery appears to be accelerating amid recent news and several sector developments. Uranium prices are up approx. 10% in the last several months and UxC Weekly notes that spot uranium activity has been at higher levels in terms of both number of transactions and volume. Analysts that cover the sector have stated that this could be a sustained upswing as they are currently seeing some of the best fundamentals since pre-Fukushima which should be supportive of higher uranium prices as a major supply-side response is playing out while the sticky demand-side continues to improve. Uranium production is on the decline and expected to be approx. 135 million lbs U3O8 in 2018 given recent closures and project deferrals while demand continues to rise and is expected to be approx. 192 million lbs as per UxC in 2018. The spot uranium price is just over $23 / lb U3O8 which is well below the average global cost of production and significant price appreciation is needed to justify this production as well as developing new mines to ensure sustainable and secure supply to meet growing global demand.

In more recent news, mine closures and production curtailment continue to dominate headlines while US lawmakers are starting to take notice of external pressures on what is deemed a strategic industry. The USA has to import approx. 93% of its required uranium for its nuclear power plants and as a result the Trump Administration has recently instructed the US Department of Energy to halt uranium sales to fund decommissioning projects and has also placed a two year moratorium on nuclear plant closures. Outside of the USA, major production cuts and depleting mine reserves appear to be working their way into the uranium market and driving prices higher. The two largest producers, Cameco and KazAtomProm, have announced large supply cuts in 2017 and 2018 including Cameco’s suspension of operations at the world’s largest uranium mine, McArthur River, as well as KazAtomProm’s announcement that it will cut 20% of planned production over the next three years and produce 60.1 million lbs in 2018. More recently, the Kazakh Energy Minister suggested there would be another 6% production cut over previous expectations to 56.2 million lbs which has further sparked a rally in the uranium price. Additionally, a new uranium holding company is emerging called “Yellow Cake” which is seeking US$150-200 million in a London-based IPO to buy 8.1 million lbs of uranium from KazAtomProm representing a significant portion of the uranium spot market which should help take further spot supply from circulation. There has also been recent talk that current producers are more likely to buy larger quantities of material from the spot market going forward which should add upward pressure to the uranium price.

On the demand side, there are just under 450 operating nuclear reactors and 58 new reactors under construction globally, with construction of five new units commencing in 2018 to-date. China continues to be at the forefront of demand growth and has the largest reactor pipeline by far, including 38 operating reactors, 20 under construction, and another 184 planned or proposed, making up approx. 38% of the global pipeline of non-operating units. Furthermore, the situation in Japan finally seems to be improving with eight reactors at full commercial operation with several more slated to come back online shortly, up from just three at this time last year. Japan has reiterated a long term nuclear commitment of 20-22% of its power mix by 2030.

Moore Uranium Project Overview:

In June 2016, Skyharbour secured an option to acquire Denison Mine's Moore Uranium Project, on the southeastern side of the Athabasca Basin, in northern Saskatchewan. The project consists of 12 contiguous claims totaling 35,705 hectares located 42 kilometres northeast of the Key Lake mill, approx. 15 kilometres east of Denison’s Wheeler River project, and 39 kilometres south of Cameco’s McArthur River uranium mine. Unconformity style uranium mineralization was discovered on the Moore Project at the Maverick Zone in April 2001. Historical drill highlights include 4.03% eU3O8 over 10 metres including 20% eU3O8over 1.4 metres, and in 2017, Skyharbour announced drill results including 6.0% U3O8 over 5.9 metres including 20.8% U3O8 over 1.5 metres at a vertical depth of 265 metres. In addition to the Maverick Zone, the project hosts other mineralized targets with strong discovery potential which the Company plans to test with future drill programs. The project is accessible via winter and ice roads which simplifies logistics and lowers costs.
