Altiplano Reports on New Targets for Exploration at the Historic Rosario Mine in

Chile

APN: TSXV

9AJ1: FWB

EDMONTON, April 30, 2018 /CNW/ - Altiplano Minerals Ltd. (TSX-V:APN) (OTCQB:ALTPF) (FWB:9AJ1)

("APN" or the "Company") is pleased to report on new targets for further exploration at the historic

Rosario Copper-Gold Mine ("Rosario"), near La Serena, Chile, including underground development,

underground drilling and identification of potential sources for new mineralized vein material.

CEO John Williamson stated, "The positive results from our exploration of the historic Farellon mine were

in line with the Company's expectations and, as a result, the Company has moved to accelerate

exploration efforts on the nearby Laura and Rosario veins, which are part of the Farellon structural

system."

At the historic Farellon Cu-Au Mine, detailed geological work has been completed, including underground

infrastructure surveying, underground sampling, underground and surface mapping, and a 2,000 tonne

bulk sample (released April 13, 2018). A second 5,000 tonne bulk sample at Farellon is nearing

completion, with the results of this work having the potential to upgrade mineral resources at Farellon and

help build a basis for analyzing economic potential going forward.

Over the past three months, the Company has also explored the Rosario and Laura Cu-Au vein systems,

which are near the historic Farellon Mine and known to have had historic production. This exploration was

comprised of surface and underground mapping, underground sampling and surveying, and surface

ground geophysical surveying. The mineralogy and textures observed at the Rosario vein (see Photo 1

below) are similar to the Farellon vein, consisting of apatite/actinolite, magnetite and chalcopyrite-rich

bands.

Assay results from underground channel sampling of Rosario include up to 6.1 % Cu in 0.5 m, consistent

with grab sample results of up to 8.7 % Cu reported by Apex Geoscience Ltd. in their NI 43-101 Technical

Report dated February 10, 2017 and filed on SEDAR March 10, 2017. These results are similar, or better,

in grade and width than initial sampling at the nearby Farellon Vein system. In addition, results of ground

magnetic surveying indicate strong anomalies that correlate with surface outcrops and underground

mapping, suggesting continuation of the veins at depth and along strike (see Figure 1 below). Several

larger magnetic anomalies that are off the known trend are defined, which may be an indication of

undiscovered potential mineralization. Based on the results of fieldwork conducted and historical mining,

the Company is moving forward with engineering work to provide for planned access to the Rosario Cu-

Au vein system in anticipation of underground drilling and an initial 5,000 bulk sample.

Inferred mineral resources are not mineral reserves. Mineral resources which are not mineral reserves do

not have demonstrated economic viability. There is no guarantee that any part of the mineral resources

discussed herein will be converted into a mineral reserve in the future. Should a production decision be

made without completing a feasibility study demonstrating economic and technical viability, there would

be increased uncertainty as well as economic and technical risks associated with such production. No

production decision has been made at this time.

Osbaldo Zamora Vega, Ph.D, P.Geol., Vice President of Exploration for Altiplano, is the Qualified Person

as defined in National Instrument 43-101 who has reviewed and approved the technical contents of this

press release.
