Rise Gold Intersects High Grade Gold 600 m Below Lowest Level of
Exploration on Idaho #1 Vein at Idaho-Maryland
• New drill intercept in Idaho #1 Vein assays 46.3 gpt gold / 1.07 m (1.35 oz per ton / 3.5 ft)
within broader interval assaying 9.4 gpt gold over 5.94 m
• New intercept ~600 m downdip of Idaho 2400 level , the lowest level of exploration on
Idaho #1 Vein, confirming exploration target for the Idaho #1 Vein with dimensions of
600 m x 600 m and remaining open-to-depth
• Recent drilling and re- interpretation of prior drill hole I -19-13 suggest an additional
major exploration target on the Idaho #2 Vein with dimensions of 1,000 m x 1,400 m
• Assays pending for drill holes I-19-14 & I-19-14A
May 21, 2019 – Vancouver, British Columbia – Rise Gold Corp. (CSE: RISE, OTCQB: RYES)
(the “Company”) is pleased to announce additional assay results from on -going diamond core
drilling at the Idaho-Maryland (“I-M”) Gold Project.
The exploration drill program at the Idaho- Maryland continues to intercept high -grade gold
mineralization in multiple vein structures downdip from hist oric workings . R ecent drilling
intersected the Idaho #1 Vein ~600 m downdip of the Idaho 2400 level.
The new intercept from drill hole I -19-12B confirms a large exploration target on the Idaho #1
Vein with dimensions of approximately 600 m on strike and 600 m downdip.

Including 1369.74 1370.11 111.5 0.37 Idaho #1
*The Company is not able to estimate true widths for the intersected mineralization until further drilling is completed.
High-grade gold mineralization was encountered in drill hole I -19-12B which assayed 46.3 gpt
gold over 1.07 m (1.35 oz per ton over 3.5 feet), including a higher grade interval of quartz veining
with visible gold assaying 111 gpt gold over 0.37 m (3.24 oz per ton over 1.2 ft). The high-grade
- 2 -
mineralization was included within a broader zone of gold mineralization assaying 9.4 gpt over
5.94 m (0.27 oz per ton / 19.5 ft).
Rise Gold has interpreted this intercept to represent a down-dip extension of the historic Idaho #1
Vein. Similar to the geology of the historic Idaho #1 Vein , the mineralized zone encountered in
I-19-12B is located between a diabase dike on the hanging wall and the ankeritized serpentinite
unit in the footwall. It differs from the historic vein in that it is composed of a group of closely
spaced narrow quartz veins hosted in volcanic andesite approximately 25 meters from the
serpentinite contact whereas the historic vein was noted to be directly on the contact. This contact
appears to be an important ore control for the Idaho #1 Vein mineralization.
A large exploration target on the Idaho #1 Vein is now defined by:
• Historic mining of high-grade mineralization above the Idaho 2000 level.
• Historic mapping and sampling of high-grade gold mineralization on both the Idaho 2400
west and east levels. Both levels were noted to be in mineralization at the mine’s
shutdowns in 1942 and 1955.
• Previous drill hole I-18-11 which intersected significant gold mineralization above and to
the west of drill hole I-19-12.
• New drill hole intercept I-19-12B, located ~600 m downdip from the Idaho 2400 level
• The target remains open-to-depth.
The Idaho #1 Vein was the most productive and highest-grade vein of the I -M Mine. Historic
production from the Idaho #1 Vein is estimated at 935,000 oz of gold with an average head grade
of 38.7 gpt (1.12 opt) gold. Total historic production from the combined Idaho veins is estimated
at 1,621,000 oz of gold with an average head grade of 28.4 gpt (0.74 opt) gold.
Two holes were wedged from the previous drill hole I-18-12. Drill hole I-19-12A was prematurely
abandoned due to the larger than expected depth to the target; drill hole I-19-12B was wedged and
drilled at a more favorable orientation and successfully intersected the Idaho #1 Vein.
A summary of drill hole assay results from I-19-12B on the Idaho #1 Vein target are presented in
Table 1. Figures 1 and 2 illustrate the recent drill intercepts with respect to the Idaho vein targets.

Idaho #2 Vein - Reinterpretation of intercepts from I-19-13 and I-19-13A
The Company previously disclosed high- grade gold mineralization in drill holes I -19-13 &
I-19-13A by news release dated March 19th, 2019:
• The vein in I-19-13 assayed 5.5 gpt gold over 5.12 m (0.16 opt / 16.8 ft).
• The vein in I-19-13A assayed 90.4 gpt gold over 4.27 m (2.64 opt / 14.0 ft).

Subsequent drilling has revealed that these intercepts are on the Idaho #2 Vein rather than on the
Idaho #1 Vein.
Recent drill holes I-19-14 & I-19-14A both intersected significant quartz veining and alteration in
association with the Idaho #2 Vein system. Assays for these holes are pending and will be released
as received.
The reinterpretation of the mineralization in drill holes I-19-13 and I-19-13A as the Idaho #2 Vein
has important implications for exploration and resource potential:
• The Idaho #2 Vein and the 52 Vein are now interpreted to be the same vein structure
making it a more significant exploration target than previously believed.
• Drilling and historic mapping indicate a strike length of the Idaho #2 Vein of up to 550 m
at the elevation of holes I-19-13 & I-19-14.
• Rise Gold’s drill holes through this area have consistently intersected the Idaho #2 Vein
along this strike length. These results were previously disclosed as the 52 Vein with assays
as high as 149 gpt over 6.8 meters.

• Previous deep intercept from Rise drill hole B-18-05, which assayed 23.7 gpt gold over
4.5 m, may represent a downdip extension of either the Idaho #2 Vein or possibly the
Idaho #3 Vein. The intercept in B-18-05 would be ~1,400 m downdip from a projection
of the Idaho #2 Vein.

• The Idaho #2 Vein in conjunction with the Idaho #3 presents an exploration target of
~1,000 m along strike and ~ 1,400 m downdip. This is exclusive of the Idaho #1 target
previously discussed.
• The untested Idaho #5 Vein is parallel and behind the Idaho #3 Vein and could likely be
tested with the same holes targeting the Idaho #3 Vein.
Figure 3 displays recent drill intercepts on the Idaho #2 Vein, the possible correlation with drill
hole B-18-05, and the exploration target for the Idaho #2 and Idaho #3 veins.

Cymoid Loops and New Linking Vein on Idaho #1
Recently drilling has revealed changes in the structural relationships of the Idaho veins at depth.
Current interpretations indicate that the Idaho Mine is comprised of a series of linked veins or
“cymoid loops”.
This is a common structural feature in Grass Valley gold deposits and important for discovery and
definition of the high-grade gold ore shoots. The Idaho #3 ore shoot was discovered in 1929 by
following the Idaho #2 (Dorsey Vein) into the footwall of the #1 Vein.
The sequence of Idaho veins in the historic production levels can be followed in order from the
Morehouse to the Idaho #5 Vein as shown in Figure 4.
FIGURE 4 – Idaho Vein Structures at Upper Level of Historic Mining – Plan View
Recent drilling has revealed that the Idaho #2 Vein has become a major mineralized structure at
depth and is no longer a linking vein between the #1 and #3 V eins. Deep drill holes in the Idaho
#1 suggest that there may be a new linking vein structure which may join the Idaho #1 Vein to the
Idaho #3 or #5 Vein , as shown in Figure 5. Historic mapping on the lowest level of the mine
supports this interpretation with the Idaho #5 Vein shown moving behind the Idaho #3 Vein.
The Idaho #5 Vein has not been tested to -date but there is potential for major ore shoots to form
on this structure in addition to the targets on the Idaho #1, #2, and #3 Veins. Continued exploration
drilling will further develop the relationships between the multiple mineralized structures at the
- 7 -
Idaho-Maryland Mine, lead to the discovery of new mineralized ore shoots, and further outline the
overall resource potential of the property.

Quality Control and Assay Methods
Richard Lippoth, M.Sc, Reg. SME, the qualified person for the exploration drill results disclosure
contained in this news release, has studied the drill core discussed in this news release and has
reviewed the analytical and quality control results. Mr. Lippoth has reviewed and approved the
scientific and technical contents of this news release.
Benjamin Mossman, P.Eng, CEO of Rise Gold, is the qualified person for the historic production
disclosure contained in this news release . Historic production at the Idaho- Maryland Mine is
disclosed in the Technical Report on the Idaho- Maryland Project dated June 1st, 2017 and
available on www.sedar.com.
Rise has implemented a quality control program for its drill program to ensure best practice in the
sampling and analysis of the drill core. This includes the insertion of blind blanks, duplicates and
certified standards. HQ- and NQ-sized drill core is saw cut with half of the drill core sampled at
intervals based on geological criteria including lithology, visual mineralization, and alteration. The
remaining half of the core is stored on- site at the Company’s warehouse in Grass Valley,
California. Drill core samples are transported in sealed bags to ALS Minerals analytical assay lab
in Reno, Nevada.
All gold assays were obtained using a method of screen fire assaying. This procedure involves
screening a large pulverized sample of up to 1 kg at 100 microns. Any +100 micron material
remaining on the screen is retained and analyzed in its entirety by fire assay with gravimetric finish
and reported as the Au (+) fraction result. The –100 micron fraction is homogenized and two sub-
- 8 -
samples of 30-50 grams are analyzed by fire assay with AAS finish. If the grade of the material
exceeds 10 gpt the sample is re-assayed using a gravimetric finish. The average of the two results
is taken and reported as the Au ( -) fraction result. All three values are used in calculating the
combined gold content of the plus and minus fractions.
