YORK, NY - August 4, 2014 - Actinium Pharmaceuticals, Inc. (NYSE MKT: ATNM) ("Actinium" or "the Company"),
a biopharmaceutical company developing innovative targeted payload immunotherapeutics for the treatment of advanced cancers, today
provided a Mid-Year Corporate Update to new and existing shareholders. The highlights below underscore the significant progress

Achievements in 2014
team wishes to thank our existing shareholders for their faith in Actinium this year." stated Kaushik J. Dave, Ph.D., President
and Chief Executive Officer. "As can be clearly seen from the highlights of our achievements listed above and elucidated
below, we have made great progress since our shareholder update in December 2013. However, we are acutely aware that delivering
on our primary objectives of bringing Iomab -B to market in 2017 and establishing the clinical validity of Actimab-A for
the treatment of Acute Myeloid Leukemia (AML), requires us to meet nearer-term milestones on time. I assure you that our entire
team is energized and completely focused on meeting our corporate objectives".
AND HIGHLIGHTS FOR 2014 YTD
successfully uplisted from the OTC bulletin board to the NYSE-MKT, a national exchange, in March 2014. This action enables a broader
base of potential investors to invest in our strong future. We were privileged to join the broad-market Russell 3000 Index
as well as the Russell 2000 , Russell Global and Russell Microcap on June 27, 2014. These exchange and index inclusions
coupled with our investor outreach efforts have resulted in greater than 12x improvement in liquidity (3-month average daily trading
volume) since the last shareholder update in December 2013. Additional equity research coverage was initiated in July 2014
by Canaccord Genuity and featured a favorable rating and outlook for Actinium along the same line as the views of the existing
Laidlaw analyst. We continue to extend our outreach efforts to buy and sell-side research analysts and portfolio managers in order
to gain greater visibility and research coverage. We believe that our efforts should result in greater liquidity for our existing
shareholders as appreciation of Actinium's prospects with a wider audience takes hold and investor purchases increase.
completed an underwritten secondary offering in June of 2014 which provided us $13.7 million and sufficient additional capital
to fund our accelerated development activities with Iomab -B and expand our clinical trial of Actimab-A for which we expect
to release interim results by year-end. The strengthened balance sheet leaves the company with sufficient capital resources
to meet our major near-term milestones which is of great comfort. Equally important, the potential inherent in our technology
platform and core Iomab -B and Actimab-A programs is further validated by our ability to attract top caliber, senior executives,
each with more than 20-years of experience and prior success in the healthcare industry. The Team will play a critical role in
ensuring that we meet or exceed our objectives across all key areas including Clinical Operations, Regulatory and Quality, Development,
Investor and Public Relations, and Business Development.
the Company's lead radioimmunotherapy asset, is on the cusp of entering a Pivotal Phase 3 trial to potentially address the
significant unmet medical need for older patients who require less toxic conditioning prior to a bone marrow transplant. Since
the last shareholder update, we have executed an agreement with ACT Oncology, a full-service, oncology focused, clinical research
organization, to help us prepare and execute the Phase 3 clinical trial of Iomab -B. We have started preparations for the
trial, including centers recruitment feasibility study and outreach. In addition, we have worked diligently to put in place strong
partners to ensure the highest quality manufacturing, labeling, and distribution of Iomab -B to support both the clinical
trial and potential commercialization. The necessary scale-up and validation for both the mAb and Iomab -B finished drug
product are currently at an advanced stage. Iomab -B is a complex program and therefore we are making sure that we address
all the requirements for not only a successful pivotal clinical study but also to ensure rapid regulatory approval and support
are pleased to report to our shareholders that the proof of concept data for Iomab -B and the significant medical advance
this drug candidate represents has attracted tremendous support from the thought leaders in bone marrow transplant. We are very
pleased to be able to showcase their enthusiastic endorsement of Iomab -B and our plans in a short three minute video we
have posted on our web site entitled "Highlights from NY BIO Panel Discussion". Please
do take a look. We are humbled that we have been provided with the fantastic opportunity to be part of the development process
that will bring such a lifesaving drug to patients who currently have no treatment options. In doing so, we will be well advised
and supported by our recently constituted Iomab -B Scientific Advisory Board which includes luminaries from some of the
most prestigious cancer and transplant centers including: the Fred Hutchinson Cancer Research Center, Memorial Sloan Kettering
Cancer Center, Case Western Reserve University, the Colorado Blood Cancer Institute, and Baylor Research Institute. This high-profile
visibility and support is expected to significantly influence the medical community and enable Actinium to develop Iomab -B
to the fullest extent of its potential in AML and in several other blood cancers where it has shown promise.
continue to march forward with the Actimab-A Phase 1/2 trial and are on target to reveal interim results in December by
the annual meeting of the American Society of Hematology, the preeminent scientific society for blood cancer research. We recently
added Baylor Charles A. Sammons Cancer Center, one of the largest oncology centers in the nation treating over 55,000 cancer patients
every year, as a clinical trial site. They join several top US cancer centers including Memorial Sloan Kettering Cancer Center,
MD Anderson Cancer Center, Fred Hutchinson Cancer Research Center, Johns Hopkins Medicine and University of Pennsylvania Health
System. The addition of Baylor and other leading cancer centers with which we are in active discussions to join in the near future
will support the ongoing enrolment in our Phase 1/2 study. Separately, we recently announced the development of another antibody-actinium-225
labeled construct to support a third clinical program at Memorial Sloan Kettering Cancer Center and will look to advance select
additional programs where we already have a significant amount of both clinical and preclinical data.
plainly demonstrated above, we have been extremely busy this year executing on our plans to deliver on the business plan for both
the near-term and longer-term", stated Dr. Dave, "In the near-term, we expect to release interim results on the Actimab-A
trial in December and to begin the Iomab -B trial in the first half of 2015. Longer-term, we expect to deliver on our primary
objectives of bringing Iomab -B to market in 2017 and establishing the clinical validity of Actimab-A, as we seek to build
an advanced, world-class oncology company that can address challenges of many types of cancer. We are confident our technologies
can provide us with many potentially first-in-class drugs to address unmet medical needs".
conclusion," stated Dr. Dave, "we are proud to report to our shareholders that Team Actinium has made material progress
on all fronts to date in 2014 including: pipeline advances, a much improved stock market profile, a stronger balance sheet, a
fortified executive team and high-profile support from prominent scientific leaders. This progress, dear shareholders, leaves
your company well-positioned to capitalize on the promise of its product candidates to deliver value. We thank-you once again
for your support and hope that you will be with us to share our future successes."
