    VANCOUVER, April 2 /PRNewswire/ - Hope Bay Gold Corporation (HGC-TSE) and
 Miramar Mining Corporation (MAE-TSE) today reported that initial results from
 drilling at the Hope Bay project in Nunavut has confirmed the presence of
 previously indicated mineralization, potentially extending the Boston gold
 deposit to the south. An expanded drill program is nearing completion in this
 area. In addition, reverse circulation drilling further south, at the Miksa
 and Domani targets, has encountered favourable indications for additional gold
 mineralization. Drill testing of the most favourable part of the Miksa target
 is planned to commence shortly.
 
     Highlights of the results from the Boston drilling are summarized below
 and details are attached.

     "These initial results suggest that we may have been able to define
 additional mineralization south of the Boston deposit," said Tony Walsh,
 Miramar Mining's President and CEO. "These areas could provide additional,
 relatively shallow resources that could be accessed by extending the existing
 ramp to the south were sufficient resources defined, complementing the already
 existing resources at Boston(x)." Based on 2000 drilling, the Boston deposit
 contains a measured and indicated resource of 651,000 oz from 1.3 million
 tonnes averaging 15.2 g/t gold, plus a significant inferred resource, as
 reported in a news release dated November 21, 2000.
     "These initial holes confirm our opinion that the Boston deposit has
 potential for expansion," said David Fennell, Hope Bay Gold's President & CEO.
 "The expanded drill program will give us a good indication of the potential of
 these trends, which remain open to depth, while drilling at Miksa further
 south opens up the potential for more discoveries in the Boston area(x)."
 
     Boston South
     ------------
     During the latter part of 2000, the Hope Bay Joint Venture drilled
 several holes from surface to test for possible extensions to the B2 Zone,
 south of the ramp at the Boston deposit. Several narrow but high grade
 intercepts were encountered, including hole S239 that intercepted 2.9 oz/t
 gold over a true width of 9.5 feet, hole S242 that intercepted 9.1 oz/t gold
 over a true width of 1.8 feet, and hole S243 that intercepted 5.0 oz/t gold
 over a true width of 2.4 feet, as reported in a news release dated November 8,
 2000. The initial step out drilling program of 12 holes has been completed and
 has indicated potential for additional resources south of the main Boston
 deposit and, as a result, the drill program was expanded to a total of 27
 holes, 25 of which have been completed and assays have been received for 19.
 The remaining holes are targeting the interpreted higher-grade trends.
     This drilling has indicated the presence of up to three possible lenses
 that plunge steeply to the south, at a slightly shallower angle than similar
 shoots identified in the main Boston deposit. The southern most mineralized
 lens has been defined approximately 100m down plunge and is open to depth. Two
 additional lenses are also indicated and are also open at depth. Drilling is
 continuing, and the remaining results are expected to be available within
 three to four weeks(x).
 
     Boston B3 Zone
     --------------
     Several of the drill holes targeting the B2 Zone at Boston were designed
 to test the B3 Zone as well, while others passed through less prospective
 portions of the B3 on the way to the B2 Zone. Results received to date are
 attached and suggest that, in the area tested, the B3 Zone has limited
 potential for hosting significant resources. No additional work is planned on
 the B3 Zone, except for B2 Zone holes that pass through the B3 Zone on the way
 down(x).
 
     Reverse Circulation Drilling
     ----------------------------
     The Hope Bay Joint Venture has commenced an extensive reverse circulation
 ("RC") drill program designed to provide preliminary tests of several gold
 targets identified on the Hope Bay belt during 2000. This program is well
 underway and is proving to be a cost effective exploration tool for covered
 areas on the belt. The principal areas targeted are Miksa, Domani and Chicago.
 
     Miksa
     The Miksa target, located approximately 1-2km south of Boston, covers an
 area where the shear structures at Boston and Domani are speculated to
 converge, creating a favourable setting for gold mineralization(x). 48 shallow
 RC holes have delineated two areas of anomalous gold and arsenic geochemistry
 coincident with iron carbonate alteration, quartz veining and sulphides. These
 anomalies are based on sampling of bedrock and of the immediately overlying
 basal till, and have been traced over an area 800m by 500m. The strength of
 these anomalies is comparable to that defined in an orientation survey drilled
 over the main Boston deposit. Based on these positive results, a seven hole,
 1,000m core drilling program is planned to test the most favourable parts of
 the Miksa trend for possible new gold deposits(x).
 
     Domani
     Ten angled RC holes have been completed in four separate areas of the
 Domani trend, which lies 4-6km south of the Boston deposit. Six of the drill
 holes at the southern and central portion of the 2.6km long Domani trend
 intersected wide zones (in excess of 15m) of moderate to strong dolomite-
 sericite altered basalts, a combination favourable for hosting gold
 mineralization. In the southern holes, the altered zones also contained quartz
 veining (up to 30%) and localized zones with pyrite. Assay results from this
 program are pending.
 
     Chicago
     The RC drill rig has now moved to the Chicago target, located 11km
 southwest of the Boston deposit, where it will be used to test the potential
 for volcanogenic massive sulphide (VMS) gold-silver mineralization hosted in
 felsic volcanics(x). Drilling is planned to test an area where surface
 sampling in 2000 returned significant gold values ranging up to 45g/t and very
 high silver values ranging up to 3,000-6,000 g/t, as reported in a news
 release dated October 10, 2000. Fifteen RC drill holes are planned to test
 continuity of this mineralization and to see if the outcropping mineralization
 is indicative of a buried gold and silver-rich VMS target in a setting perhaps
 analogous to the Bousquet mine in Quebec(x). This area also has yielded base
 metal anomalies that could develop into polymetallic targets(x).
 
     2001 Work Program Progress
     --------------------------
     In addition to the continuing work discussed above, drilling was recently
 completed at Doris Connector and is continuing on the Naartok-Matrim trend. At
 Doris Connector, seven holes totalling approximately 1,400m were completed and
 assay results are pending. On the Naartok-Matrim-Patch trend, approximately
 8,700m of drilling in 45 holes over a strike length of 1,400m has been
 completed. Since assays are pending on numerous holes, the drilling activity
 has been reduced from three to one drill until assaying catches up and any
 required follow-up drilling can be properly planned. Results for the Doris
 Connector and Naartok-Matrim-Patch trend will be released once sufficient
 results are available(x).
 
     Hope Bay Project
     ----------------
     Miramar Mining Corporation, through its wholly owned subsidiary Miramar
 Hope Bay Ltd., and Hope Bay Gold Corporation Inc. are in a 50-50 joint venture
 at Hope Bay and control virtually the entire 80km long Hope Bay Archean
 greenstone belt. There are 1.3 million oz of near surface, high-grade measured
 and indicated mineral resources in 2.5 million tonnes grading 16.9 g/t gold at
 Boston and Doris and a further 579,000 oz in 1.1 million tonnes grading 16.8
 g/t gold at Doris in the inferred mineral resource category. In addition to
 these higher-grade mineral resources, there are significant additional lower
 grade resources at Boston and Madrid. Details of mineral resource estimates
 were reported in a news release dated November 21, 2000 and are available on
 the Miramar or Hope Bay Gold websites at http://www.miramarmining.com/ or
 http://www.hbgold.com/ along with all joint venture results for the 2000 work
 program.
 
     Quality Assurance/Quality Control
     ---------------------------------
     The work program being conducted at Hope Bay and the results contained
 herein are reported under an extensive quality control program supervised by
 Dean McDonald, P.Geo. Ph.D., Exploration Manager with Miramar Mining
 Corporation, who is an appropriately qualified person as defined by National
 Instrument 43-101. To further ensure the integrity of exploration results, the
 Hope Bay Joint Venture had Roscoe Postle & Associates independently audit
 quality control and quality assurance ("QA/QC") programs in place at the Hope
 Bay project. See News Release 00-06 dated April 11, 2000 for details on the
 program. This QA/QC program includes on site control of core samples and a
 program of duplicate, check, and blank assaying, including check assaying at a
 separate laboratory. Roscoe Postle found that the quality of these QA/QC
 programs exceeded industry standards. Dr. McDonald has corroborated the data,
 including sampling, analytical and test data, on which the above information
 is based.
     All samples are assayed at TSL Laboratories in Saskatoon using standard
 sample preparation and fire assay procedures with a gravimetric finish. All
 samples assaying over 20 g/t are re-assayed with a standard metallics
 procedure.
     All resource estimates have been prepared by independent resource
 consultant Geostat Systems Inc. of Montreal with the assistance of the Hope
 Bay Joint Venture staff in accordance with the standards set out in National
 Instrument 43-101 and reviewed by Dean McDonald, P. Geo. Ph.D., Exploration
 Manager with Miramar Mining Corporation, who is an appropriately qualified
 person as defined by National Instrument 43-101. Mineral resources that are
 not mineral reserves do not have demonstrated economic viability.

 Miramar Mining's President and CEO. "These areas could provide additional,
 relatively shallow resources that could be accessed by extending the existing

 contains a measured and indicated resource of 651,000 oz from 1.3 million
 tonnes averaging 15.2 g/t gold, plus a significant inferred resource, as
 reported in a news release dated November 21, 2000.
     "These initial holes confirm our opinion that the Boston deposit has

     Boston South
     ------------
     During the latter part of 2000, the Hope Bay Joint Venture drilled
 several holes from surface to test for possible extensions to the B2 Zone,
 south of the ramp at the Boston deposit. Several narrow but high grade
 intercepts were encountered, including hole S239 that intercepted 2.9 oz/t
 gold over a true width of 9.5 feet, hole S242 that intercepted 9.1 oz/t gold
 over a true width of 1.8 feet, and hole S243 that intercepted 5.0 oz/t gold
 over a true width of 2.4 feet, as reported in a news release dated November 8,
 2000. The initial step out drilling program of 12 holes has been completed and
 has indicated potential for additional resources south of the main Boston
 deposit and, as a result, the drill program was expanded to a total of 27
 holes, 25 of which have been completed and assays have been received for 19.
 The remaining holes are targeting the interpreted higher-grade trends.
     This drilling has indicated the presence of up to three possible lenses
 that plunge steeply to the south, at a slightly shallower angle than similar
 shoots identified in the main Boston deposit. The southern most mineralized
 lens has been defined approximately 100m down plunge and is open to depth. Two
 additional lenses are also indicated and are also open at depth. Drilling is
 continuing, and the remaining results are expected to be available within
 three to four weeks(x).
 
     Boston B3 Zone
     --------------
     Several of the drill holes targeting the B2 Zone at Boston were designed
 to test the B3 Zone as well, while others passed through less prospective
 portions of the B3 on the way to the B2 Zone. Results received to date are
 attached and suggest that, in the area tested, the B3 Zone has limited
 potential for hosting significant resources. No additional work is planned on
 the B3 Zone, except for B2 Zone holes that pass through the B3 Zone on the way
 down(x).
 
     Reverse Circulation Drilling
     ----------------------------
     The Hope Bay Joint Venture has commenced an extensive reverse circulation
 ("RC") drill program designed to provide preliminary tests of several gold
 targets identified on the Hope Bay belt during 2000. This program is well
 underway and is proving to be a cost effective exploration tool for covered
 areas on the belt. The principal areas targeted are Miksa, Domani and Chicago.
 
     Miksa
     The Miksa target, located approximately 1-2km south of Boston, covers an
 area where the shear structures at Boston and Domani are speculated to
 converge, creating a favourable setting for gold mineralization(x). 48 shallow
 RC holes have delineated two areas of anomalous gold and arsenic geochemistry
 coincident with iron carbonate alteration, quartz veining and sulphides. These
 anomalies are based on sampling of bedrock and of the immediately overlying
 basal till, and have been traced over an area 800m by 500m. The strength of
 these anomalies is comparable to that defined in an orientation survey drilled
 over the main Boston deposit. Based on these positive results, a seven hole,
 1,000m core drilling program is planned to test the most favourable parts of
 the Miksa trend for possible new gold deposits(x).
 
     Domani
     Ten angled RC holes have been completed in four separate areas of the
 Domani trend, which lies 4-6km south of the Boston deposit. Six of the drill
 holes at the southern and central portion of the 2.6km long Domani trend
 intersected wide zones (in excess of 15m) of moderate to strong dolomite-
 sericite altered basalts, a combination favourable for hosting gold
 mineralization. In the southern holes, the altered zones also contained quartz
 veining (up to 30%) and localized zones with pyrite. Assay results from this
 program are pending.
 
     Chicago
     The RC drill rig has now moved to the Chicago target, located 11km
 southwest of the Boston deposit, where it will be used to test the potential
 for volcanogenic massive sulphide (VMS) gold-silver mineralization hosted in
 felsic volcanics(x). Drilling is planned to test an area where surface
 sampling in 2000 returned significant gold values ranging up to 45g/t and very
 high silver values ranging up to 3,000-6,000 g/t, as reported in a news
 release dated October 10, 2000. Fifteen RC drill holes are planned to test
 continuity of this mineralization and to see if the outcropping mineralization
 is indicative of a buried gold and silver-rich VMS target in a setting perhaps
 analogous to the Bousquet mine in Quebec(x). This area also has yielded base
 metal anomalies that could develop into polymetallic targets(x).
 
     2001 Work Program Progress
     --------------------------
     In addition to the continuing work discussed above, drilling was recently
 completed at Doris Connector and is continuing on the Naartok-Matrim trend. At
 Doris Connector, seven holes totalling approximately 1,400m were completed and
 assay results are pending. On the Naartok-Matrim-Patch trend, approximately
 8,700m of drilling in 45 holes over a strike length of 1,400m has been
 completed. Since assays are pending on numerous holes, the drilling activity
 has been reduced from three to one drill until assaying catches up and any
 required follow-up drilling can be properly planned. Results for the Doris
 Connector and Naartok-Matrim-Patch trend will be released once sufficient
 results are available(x).
 
     Hope Bay Project
     ----------------
     Miramar Mining Corporation, through its wholly owned subsidiary Miramar
 Hope Bay Ltd., and Hope Bay Gold Corporation Inc. are in a 50-50 joint venture
 at Hope Bay and control virtually the entire 80km long Hope Bay Archean
 greenstone belt. There are 1.3 million oz of near surface, high-grade measured
 and indicated mineral resources in 2.5 million tonnes grading 16.9 g/t gold at
 Boston and Doris and a further 579,000 oz in 1.1 million tonnes grading 16.8
 g/t gold at Doris in the inferred mineral resource category. In addition to
 these higher-grade mineral resources, there are significant additional lower
 grade resources at Boston and Madrid. Details of mineral resource estimates
 were reported in a news release dated November 21, 2000 and are available on
 the Miramar or Hope Bay Gold websites at http://www.miramarmining.com/ or
 http://www.hbgold.com/ along with all joint venture results for the 2000 work
 program.
 
     Quality Assurance/Quality Control
     ---------------------------------
     The work program being conducted at Hope Bay and the results contained
 herein are reported under an extensive quality control program supervised by
 Dean McDonald, P.Geo. Ph.D., Exploration Manager with Miramar Mining
 Corporation, who is an appropriately qualified person as defined by National
 Instrument 43-101. To further ensure the integrity of exploration results, the
 Hope Bay Joint Venture had Roscoe Postle & Associates independently audit
 quality control and quality assurance ("QA/QC") programs in place at the Hope
 Bay project. See News Release 00-06 dated April 11, 2000 for details on the
 program. This QA/QC program includes on site control of core samples and a
 program of duplicate, check, and blank assaying, including check assaying at a
 separate laboratory. Roscoe Postle found that the quality of these QA/QC
 programs exceeded industry standards. Dr. McDonald has corroborated the data,
 including sampling, analytical and test data, on which the above information
 is based.
     All samples are assayed at TSL Laboratories in Saskatoon using standard
 sample preparation and fire assay procedures with a gravimetric finish. All
 samples assaying over 20 g/t are re-assayed with a standard metallics
 procedure.
     All resource estimates have been prepared by independent resource
 consultant Geostat Systems Inc. of Montreal with the assistance of the Hope
 Bay Joint Venture staff in accordance with the standards set out in National
 Instrument 43-101 and reviewed by Dean McDonald, P. Geo. Ph.D., Exploration
 Manager with Miramar Mining Corporation, who is an appropriately qualified
 person as defined by National Instrument 43-101. Mineral resources that are
 not mineral reserves do not have demonstrated economic viability.
