Sprott Resource Holdings Inc. Announces Mineral Reserves and Resources for

Minera Tres Valles are In-Line with Management Assumptions

Sprott Resource Holdings Inc. (“ SRHI” or the “ Corporation”) (TSX: SRHI) is pleased to

announce the results of an updated NI 43-101 compliant mineral reserve and mineral resource

estimate, pre-feasibility study for the implementation of chloride media leaching (“Salt Leach”),

and feasibility study for the expansion of the Don Gabriel Manto open pit, as well as an update

on the operating and growth activities for its 70% -owned Minera Tres Valles (SpA) (“ MTV”)

property located near Salamanca, Chile.

“We are very pleased that the updated technical studies validate our investment thesis through

mineral reserve and resource estimates that are in -line with the due diligence we conducted

before acquiring the MTV asset,” said Steve Yuzpe, CEO of SRHI.

Since October 2017, MTV has been working diligently with several consulting and engineering

firms to update the historical information to provide a mineral reserve and mineral resource

estimate for the MTV property in compliance with the standards prescribed by NI 43-101, define

the capital requirements to convert the acid leach process to a Salt Leach process, and provide

a feasibility level mine plan to expand production from the Don Gabriel Manto open pit mine.

These studies, which are being compiled into a NI 43-101 compliant technical report, comprise

the first stage of the expansion of the MTV operation. In t he next stage , Wood plc (“ Wood”,

formerly AMEC Foster Wheeler ) has been engaged to complete a pre -feasibility level

underground mining study for the exploitation of the Papomono Massive underground deposit ,

with the objective of defining further mineral reserves. It is MTV’s objective to combine the

studies with preliminary economic assessment (“PEA”) level studies on ancillary deposits to

produce a property-wide production profile.

Updated Mineral Resource Estimate Highlights:

 Total measured and indicated mineral resource of 18.3 million tonnes at 1.03% CuT

containing 417 million pounds of copper

 Total inferred mineral resource of 3.5 million tonnes at 1.11% CuT containing 84.4

million pounds of copper

Salt Leach Pre-Feasibility Study Highlights:

 Potential to increase copper recoveries by 10%, up to 40% reduction of leaching cycle,

and up to 40% reduction in sulfuric acid consumption

 Estimated capital cost of US$6. 9 million, which includes the activities from detailed

engineering to the end of construction

 Approximately 11 months to implement

 Less than two year payback

Don Gabriel Manto Feasibility Study Highlights:

 Almost triples production from the Don Gabriel Manto open pit

 Mine plan based on mineral reserves of 5.17 million tonnes at 0.81% CuT at a copper

cut-off grade of 0.25%

 Produce approximately 14 million pounds of copper per year over a six-year reserve life

 Currently selecting the open pit contract mining contractor for Don Gabriel

Corporate Activity Highlights:

 Wood has commenced a pre -feasibility level underground mining study on the

Papomono Massive underground deposit

 Expanded management team to include experienced underground mining professional

to lead underground development

 Appointed Joe Phillips, a highly experienced operations and project development senior

executive, to board of directors of MTV

“These are excit ing times for SRHI as we undertake the studies to define the growth plan to

reach the full potential of the MTV asset s,” said Mr. Rick Rule, CIO of SRHI. “Chile is a

wonderful country in which to do business, and we are seeing many opportunities to expand our

operational footprint in Chile and South America.”

“Based on these studies and our prior diligence, the e xisting facilities, with an additional capital

investment allow for production expansion to reduce unit costs,” said Mr. Yuzpe. “We are

benefiting from higher copper prices and we are pleased to have reached a mutually beneficial

three year agreement with the labour union at MTV.”

“The planned tripling of open pit production will allow MTV to secure more favo urable mining

and haulage rates,” said Luis Vega, CEO of MTV . “Significant work has been completed on the

Papomono Massive deposit, and we have added an experienced project manager with

significant project and underground experience to assist with the development of the min e plan

at Papomono Massive and the other deposits.”

NI 43-101 Mineral Reserve and Mineral Resource Estimates

MTV engaged Independent Mining Consultants, Inc. (“ IMC”) of Tucson, Arizona to prepare NI

43-101 compliant mineral reserve and mineral resource estimate s and a supporting technical

report for the Don Gabriel and Papomono mines on MTV’s property located near Salamanca ,

Chile. Based on 771 diamond drill holes totaling 145.5 thousand meters, the total measured and

indicated mineral resources is 18.3 million tonnes at 1.03% copper containing 417.3 million

pounds of copper. Inferred mineral resources total 3.5 million tonnes at 1.11% copper

containing 84.4 million pounds of copper. Tables 1 and 2 summarize the mineral reserves and

mineral resources for the nine deposits comprising Don Gabriel and Papomono.

For the Don Gabriel Manto open pit deposit, IMC calculated a measured and indicated mineral

resource of 6. 5 million tonnes at a grade of 0.8 3% containing 118 million pounds at a cut -off

grade of 0.2% copper, and this mineral resource estimate was used in the Don Gabriel Manto

feasibility level open pit mine plan described below. Using a long -term copper price of

US$2.75/lb, IMC produced an optimized mine plan for the Don Gabriel Manto open pit mine,

defining proven and probable mineral reserves of 5.17 million tonnes at a grade of 0.81% CuT

containing 92.7 million pounds of copper. The Don Gabriel Vein deposit, located below the Don

Gabriel Manto open pit , is planned to be mined using underground methods. Further infill

drilling is planned to increase the confidence level and expand the mineral resource estimate for

the Don Gabriel Vein deposit.

For the Papomono Massive deposit, IMC estimated a measured and indicated mineral resource

of 3.34 million tonnes at a grade of 1.86% copper containing 137 million pounds of copper at a

cut-off grade of 0.34%.

In November 2017, Wood was engaged to develop an underground mine plan at Papomono

Massive at a pre-feasibility level. Ingeroc Ltda. has completed the geotechnical drilling program

at the Papomono Massive underground mine to assist in the trade-off studies and preparation of

the mine plan.

It is planned that th e ancillary deposits be exploited opportunistically in order to maximize

crusher feed and copper grade to the plant and provide operational flexibility. Further drilling is

required to increase the confidence level and expand the ancillary deposits.

In the next stage, MTV will incorporate the Don Gabriel feasibility study results in its study and

supporting technical report . The development of the Papomono underground is the next stage

of the expansion of the MTV mine to full capacity. MTV is expected to complete its studies and

the related technical report in the middle of 2018.

Salt Leach Pre-feasibility Study

MTV engaged ProPipe S.A. (“ProPipe”) of Santiago to undertake a pre-feasibility study on Salt

Leach to validate prior column and test-heap leach results, and define the cost and timeline for

the infrastructure and implementation. The results and more detail of this study will be included

in the IMC Technical R eport. Twelve three -meter columns and four test heap leach pads

containing 2.4 thousand tonnes of mineralized material from both Papomono and Don Gabriel

Manto demonstrated increased recovery of sulphide material, primarily chalcocite, through the

application of salt, coupled with a 30-day rest period prior to applying sulphuric acid.

Benefits of Salt Leach process include:

 More than 10% increase in overall metallurgical recoveries

 Up to 40% reduction of leach cycle time

 The Company's mineral reserve and mineral resource estimates as at January 1, 2018 are classified in

accordance with the Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") "CIM Definition Standards -

For Mineral Resources and Mineral Reserves" adopted by the CIM Council (as amended) in accordance with the

requirements of National Instrument 43-101 "Standards of Disclosure for Mineral Projects" ("NI 43-101"). Mineral

reserve and mineral resource estimates reflect the Company's reasonable expectation that all necessary permits

and approvals will be obtained and maintained.

 Mineral reserves were estimated using a copper price of US$2.75/lb.

 Mineral resources were estimated using a copper price of US$3.30/lb

 OP means open pit mining, UG means underground mining method

 Cutoff grades vary by deposit to reflect likely mining methods, variations in costs and slight variances in expected

metal recovery by deposit.

 CuT is total copper assay, comprised of acid soluble (CuS), cyanide soluble (CuCN) and residual copper (CuR),

each with different leach kinetics. Recoveries based on conversion from existing acid leach method to chloride

media acid leaching as described in this announcement and pending technical report from IMC.

 Further information, including key assumptions, parameters and methods used to estimate mineral reserves and

mineral resources will be described in the technical report on the MTV deposits to be published within 45 days of

this announcement.

 Mineral resources are reported inclusive of mineral reserves. Mineral resources that are not mineral reserves do

not have demonstrated economic viability. Mineral Resources for proposed open pit deposits are constrained

within an economic pit shell.

 The estimate of mineral resources and mineral reserves may be materially affected by environmental, permitting,

legal, title, taxation, socio-political, marketing or certain other risks. Please refer to the risks related to the mining

sector in the risk management section of the 2017 MD&A.

 Totals may not add due to rounding.

 Up to 40% reduction in sulphuric acid consumption

ProPipe has delivered a pre-feasibility level report with capital and operating cost estimates with

20% accuracy and have recent and relevant experience in building and commissioning these

systems in Chile . Capital costs including project administration, owner ’s costs, procurement,

construction, initi al fill and contingency total US$6.9 million. MTV expects a payback of the

investment in less than two years at current prices.

Main elements of the implementation include the construction of a salt -delivery system to the

agglomerator drum, conversion of pipes and valves to non -corrosive materials, change to the

extractant, the addition of a three coalescer units to reduce impurities in the organic phase and

an additional wash tank , along with minor electrical and civil works. A minimal amount of

disruption to production is expected during the transition.

Expected implementation time is 11 months from the MTV board approval including detailed

engineering, procurement, permitting, construction and commissioning. The results of this

report will be used to submit a Carta Pertinencia to SEA, the Chilean permitting authority, for the

conversion to chloride media acid leaching from the current acid leaching.

Don Gabriel Manto Feasibility Study Results

At the operating Don Gabriel Manto open pit mine, MTV plans to increase production from the

current 25 thousand tonnes per month to 70 thousand tonnes per month and will use mining

contractors to drill, blast, load and haul ore and waste. MTV’s management team has extensive

experience in negotiating with and managing mining contractors, and is targeting the increase to

a higher production rate to commence in April 2018, with minor interruption of Don Gabriel

Manto ore to the crushing plant . The mineral reserve estimate and mine plan consider a pit-

angle of 50 degrees, and a cutoff grade of 0. 25%. MTV anticipate a phased layback of 2.67

million tonnes in 2018; the life-of-mine strip ratio of 4.3:1 (waste:ore) includes the capitalized

lay-back program.

Operations Update

MTV sold 2.7 million pounds of copper in the last quarter of 2017 . Cash costs per recoverable

pound placed on the heap leach pad were US$2.37. In the fourth quarter of 2017, MTV crushed

and processed 2.3 thousand tonnes per day, a 29% increase over the average of the prior three

quarters. Total material crushed in 2017 was 682 thousand tonnes, delivering 12.9 million

pounds of recoverable contained copper to the heap leach pad. Recent increases in sulfide

material production have increased inventory build -up in the heap leach, and we expect to see

the benefit of increased mining production in the latter part of 2017 in the coming months.

Mineralized material supply from t hird party miner activity is increas ing with the higher copper

price, reaching 23 thousand tonnes in December 2017 , and t otal deliveries of third -party

material of 51 thousand tonnes in the fourth quarter. MTV expects this increase d level of third

party supply to continue in 2018, although budget s for deliveries of 15 thousand tonnes per

month. Deliveries from ENAMI were 13 thousand tonnes of mineralized material in the fourth

quarter of 2017.

In November 2017, MTV hired Jorge Baraqui, an experienced underground mining professional

with over 20 years of planning and execution of underground mining projects for Codelco. Mr.

Baraqui specializes in Block and Panel caving methods, mine preparation and mining

innovation.

In November 2017, SRHI nominated Joe Phillips to serve on the board of directors of MTV. Mr.

Phillips is currently the Vice P resident of operations for Laguna Gold , and has extensive
